Solution to use Airprint across subnets wired/wireless

A lot of companies are trying to figure out how to setup airprint to print
in the workplace, wired+wireless across subnets.
We finally figured it out with some DNS magic and a CUPS server.
I have documented the solution at a live document hosted at

Hopefully it helps a few folks.

You will want to make sure your APs can route from where ever you install them to the WLC managment address.
How APs find the controller can happen a few different ways:
1) DNS A record
2) Layer 2 broadcast (which you seen already)
3) IP Route Forward
4) DHCP Option 43
5) Manual Prime the AP
Most folks lead with option 43.

if you check the config guide you will explain the other processes.

NetBoot across subnets with a bootpd relay

Hello Apple Community!
I've got 4 subnets at my school, each with various Macs around campus. I have a Mavericks server on each subnet currently, each with their own NetBoot images. It's a pain to keep everything updated. I can get a single client Mac (pre-2011) to boot across subnets using the bless command, but that's not really a viable solution for us to run a bless command on each client every single time we want to netboot. So far, the solution has been just to have dedicated netboot servers on each subnet, but I know there has to be a better way.
This article (OS X Server: How to use NetBoot across subnets - Apple Support) describes three different methods for netbooting across subnets, but two of them are not really viable for us. Those involve reconfiguring the network to allow BootP data to pass across subnets or configuring one server with multiple network connections, one for each subnet. However, option #2 describes configuring a bootpd relay. Based on my reading, this sounds like exactly what I need. However, I can't find any good documentation to walk me through setting it up.
I've thoroughly read the bootpd man page, which has had me editing the /etc/bootpd.plist on multiple servers. This hasn't gotten me very far. My clients still don't see the remote NetBoot server. It seems like the relay is supposed to redirect broadcasts from the remote Netboot server, through a local NetBoot server to the client. But I have no idea how to make this work.
Could someone please give me more guidance on what I'm supposed to be doing here? I'd like to host a single NetBoot server and have any client on any subnet be able to option-boot to see the NetBoot startup options (I have multiple NetBoot images, from Apple Service Toolkit to DeployStudio and Mavericks/Yosemite installers in between). Even if I could get it to just netboot to one default source (AST), I could deal with that. I'm also happy to host multiple NetBoot servers, but with all my NetBoot images in one location. I'm stumped in this multiple subnet environment and I need help. Please help.

Thanks again for your feedback. I had forgotten I left the "tftp://" on the IP address. Though, I've tried that multiple ways, starting with IP only. Also, per the bootpd man page (https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/ man8/bootpd.8.html), <allow/> and <deny/> are lists for MAC address allowances and when nothing is defined everything goes through. These are there by default, though I will remove them and see what happens. Also, according to the man page, bootp_enabled enables on all connections when a boolean is set rather than an array. Though I will still change this also and see what happens. The array that comes after the netboot_disabled key is auto-generated by NetInstall when you turn the service on in Server.app.
Essentially, that plist comes from a fresh activation of NetInstall. I deleted the previous .plist, rebooted the server and when I turned on NetInstall, that's what was created, plus my bootp modifications.
All that said, you said that you assumed I started the relay with the 'debug & logging' options enabled. I haven't started the relay in any active sense. So far, I've just been modifying this .plist, and rebooting a bunch of times, but that's where I seem to get lost. Is there a way to actively "start" the relay? I'd love to look at these 'debug & logging' options. As for the 'Startup Disk' prefs on the client Mac, they do not show any significant change. Basically, they just don't see the remote server as a startup option. I have not gleaned any pertinent info from console, though I'm not sure I know what I'm looking for.
On a side note, I had a wild hair to try something different. I set my local subnet's server to look at a NetBootSP0 folder that was actually a symlink to a NetBootSP0 folder that was mounted as a file share from the remote NetBoot server. This really looked like it might work. When you boot the client, it saw the startup volumes from the remote server. However, upon boot, it doesn't seem to make the connection and winds up booting back to the internal hard drive. It was worth a try...

Airprint in the Enterprise across subnets [Solution]

This is a message to help folks figure out how to setup
Airprint across wired/wireless subnets. Hopefully it will help a few people.
Airprint was designed to work with Bonjour on a local subnet/broadcast domain.
To print in the enterprise where we have wired/wireless infrastructure,
we need to use a DNS server to find the printer resources
Assumptions:
Our internal domain is: foocompany.com
We create a new subdomain: bonjour.foocompany.com
Creating a new subdomain allows up to apply DNS views so we can show print/bonjour services in
close proximity of the user.
You have a CUPS printer server (linux/apple) running at printserver.bonjour.foocompany.com
1. Setup a DNS server
If you setting up a test domain server, you can setup forwarding to your primary production server.
This way all DNS queries continue to work
In your named.conf file setup forwarding
options {
forwarders { YOURTOPNAMESERVER_IPADDR; YOURTOPNAMESERVER_IPADDR2; };
forward first;
allow-query-cache { any; }; // Allow client queries from other subnet to query from cache
Create a new zone, "bonjour.foocompany.com"
zone "bonjour.foocompany.com." { type master; file "/etc/bind/db.home"; };
zone "foocompany.com" { type forward; forward only; forwarders { YOURTOPNAMESERVER_IPADDR; YOURTOPNAMESERVER_IPADDR2; }; };
Create the following entries to support bonjour browsing

Update for ios 8:
With ios 8 it appears that _printer and _ipp are no longer equivalent. For this to work it looks like you have to use _ipp._tcp
Also - the underscore characters are important and they are missing from the example above.
Last - you can use the "note" field to add a second line that is displayed in smaller text below the printer name in ios 8.
Here is an updated template:

Can you use AirPrint to print to hard wired printer via your WiFi network?

Recently I bought an Officejet 6700 Premium e-All-in-One to serve all my PCs in the house and to use the AirPrint functionality for all the iPhones & iPads.
The printer is located in the basement office where there is poor wireless reception, and therefore connected with a wire (ethernet) to a wireless router one level up on the ground floor. The wireless router covers & connects everything (PCs, iPhones & iPads) in rest of the house.
I do not seem to be able to set up AirPrint when the printer is connected through the ethernet to the local network. Only when I unplug the ethernet cable and connect the printer wirelessly (with poor reception) to the wireless network, I get AirPrint to work ...... As soon as I plug in the Ethernet cable the WiFi of the printer shuts off and AirPrint does not function anymore.
Is there anyway for me to keep the printer "ethernet connected" through the wire and use AirPrint ??
I underdstand ther is a lot AirPrint is wireless, but why can it not be wireless from the iPhone/iPad to the wireless router and then through the ethernet cable to hard wired printer ? It's all on the same network with proper IP addresses etc. Do not understand why the printer also needs to connect wirelessly to the router to enable AirPrint.......
thanks for helping out,

I came across this discussion when looking for a solution to a similar problem. We have an AirPrint certified printer that does not have built-in Wi-Fi. Using a USB cable it worked well with our iMac, but we also wanted to use AirPrint with our iOS devices. In our situation, we cannot run an Ethernet cable from our router (a 4th generation Airport Extreme) to either our iMac or printer. With help from Apple Support, here is what became our solution.
Using an Ethernet cable, we connected an AirPort Express router (2012 model) to the printer to provide a Wi-Fi capability to the printer. AirPrint apparently will not work with a USB cable. Because the AirPort Express was being repurposed, we reset it using what Apple refers to as a “Factory” or “Default Settings reset.” With the reset completed, the Express became visible within Airport Utility, showing a connection to the Extreme. Within Airport Utility, click on the Airport Express to open its status window; click on the Edit button, then the Wireless tab, and then select “Join a wireless network” within the Network Mode options. This made the Express into a “wireless bridge” between the printer and the Extreme, allowing our iOS devices to see the AirPrint printer. Our iMac also connects wirelessly to the printer.
Within Airport Utility, we could have selected “Extend a wireless network” as the Network Mode, however because we rely on a wireless connection between the Extreme and Express, doing so has the potential of reducing throughput among Wi-Fi devices because of the resulting network overhead. We had been using Printopia to allow our iOS devices to work with an earlier non-AirPrint printer. To avoid conflicts we turned Printopia off, accessing it within the iMac’s System Preferences. AirPrint is easier to use and provides better printer output than did Printopia.
When our HP printer sleeps, the iMac computer wakes it up as needed, however the sleeping printer becomes invisible to the iOS devices. We hope to fix this weakness, possibly by resetting the printer's sleep setting.

I am using an Airport Extreme for wireless and a Netgear VPN Switch for wired connections. How do I get the two networks to connect?

I am using an Airport Extreme for wireless and also have a Netgear VPN Switch (FV5318) for internal wired ethernet connections. How do I get the two networks to connect to each other?

Tesserax, I would like to keep the Airport Extreme in nplace before the Netgear FVS318 switch because I am using all of the 8 ethernet outputs distributed to 8 differerent locationsl This way I can just use one of the LAN outputs from the Airport to feed the FVS318. Here is what I think I am hearing you say:
Tne reason why the wired and wireless devices are not communicating is because the FVS318G is also a DHCP server and in conflict with the AEBS.
To remedy the situastion here is probably what I need to do in order:
1. Change the LAN IP Address of the Netgear FVS318G to be the same subnet of the Airport Extreme.
2. Then, disable the Netgear FVS318G as a DHCP server.
3. Make sure the ethernet cable from the LAN port of the Airport Extreme connectis to the LAN port of the Netgear FVS318G.
4. Restart everything.
Can you provide me the steps I need to take to get the right IP addresses from the Airport Extreme to put into the Netgear to fix the conflict? I have the Airport Utility. I also have two airport express hot spots, and two Apple TVs in addition to computers attached to the 8 ethernet lines.
Thank you.
Steve

Why would you need to connect an AirPort Express to a printer to print wirelessly when you could just use AirPrint?

What is the point of connecting an AirPort Express to a printer when you could just use AirPrint from an iPhone?

All you guys are mistaking the Airprint system. Wireless printing is a Misnomer. Nothing prints wirelessly. Both the printer and the computer, or i or android device have to be all connected to the same LAN. They can be connected by a wire or a WiFi signal but they all must be on the same LAN.
Airprint is a Driverless printing system where No Specific Printer drivers have to be installed on the computer or other device. Even with the Airprint system both the printer and the device you are printing from have to be on the same LAN.

Not able to use Apple tv across subnet

Hi Guys,
I have made a test setup which contain an cisco 2600 router, apple tv and Macbook pro with 10.9.2 OSX. Its pretty simple setup. One interface(Fa0/0) of the cisco router is connected to apple TV via ethernet cable in an network 10.0.1.0/24 and another interface (Fa0/1) is connected to Macbook pro in network 10.0.2.0/24 via ethernet cable. Apple TV network ip is 10.0.1.2 whereas macook ip is 10.0.2.2. I am able to succesfully ping from macbook to apple tv, but not able to discover apple tv at all on my macbook. I tried every method, allowed udp port 5353 on router for bonjour discovery , but still no luck. Can any gentleman help me on this?

Yes, we can mirror it across subnet. Thats what I am trying to figure out. People had done this eariler.

CUPS printer sharing across subnets?

I am trying to set up my local network printer so that everyone in the house can print from it. However I have two subnets in the house and I don't see how to connect to the Linux server through a Windows 7 client.
My network is like so:
Upstairs: [Modem] <=eth0=> [Router 1] Subnet of 192.168.0.*
[Router 1] <=wlan0 client mode=> Downstairs: [Router 2 with dd-wrt firmware] Subnet of 192.168.1.*
[Router 2] <=eth0=> CUPS server/PC with USB printer attached IP address of 192.168.1.1XX
This works: [Router 2] <=ath0.1 virtual wireless ESSID=> Windows 7 Laptop
This doesn't: [Router 1] <=wlan0=> Windows 7 Laptop
I tried
sudo cupsctl --share-printers --remote-any && sudo systemctl restart cups
on the host PC, but the W7 clients can't connect across subnets. Is there anyway to set it up so it can? They can easily connect to the ath0.1 network and then print, but it's inconvenient for them. The Windows users spend most of the time upstairs, and not downstairs, so they are usually connected to the wlan0 network.
I have the option of putting [Router 2] into client bridged mode so it shares the same subnet of [Router 1], however I can't seem to set it up properly and I run into problems. It is important to have the ath0.1 network downstairs, and I am unsure that client (bridged) mode will allow for the virtual interface.
I do not have Samba installed but I am considering trying that, but a simpler solution would be appreciated.
*Edited for further clarification & error fixing.

if I can share a printer between an XP system and a Win 7 system?
Before I enter all the system data, I just wondered if someone already knew the answer to this one. I was successsfully sharing a non network printer plugged into an XP machine via USB and printing to it via Network Magic from my Vista machine, but since I upgraded Vista to Win 7, I cannot. Everytime I try to install the remote printer or access it in any way from my Win 7 machine, I get the Windows message: " Windows cannot connect to the printer". This also occurs form within the Network Magic Map if I try to Complete Printer Setup. It shows up on my Win 7 machine when I want to ADD a Printer, but I cannot install it. It shows as Shared on the XP machine.
Thanks for any assistance!

Hi S.,
You need to use Network and Sharing Center and open up your computer. You need to use the Public Profile and turn on Network Discovery. Not sitting in front of Windows 7 at the moment.
Otherwise, you need a Wireless Printer or All-In One Machine or a Printer that plugs into the Router using an Ethernet Port.

Airprint across VLANs

I have a WLC 5508 controller in my environment. I'm trying to use AirPrint to attach and print to a Xerox device on a different subnet. If I statically assign an IP address to the Xerox device on my WiFi subnet, I can print to it. How should I configure the WLC and/or my Catalyst 4500/6500 switches to allow AirPrint across VLANs?

Intermittent NW problems wired/wireless

Hi,
My iMac experiences some intermittent NW problems.
Configuration:
iMac is connected (wired) to a USR router which is on its turn connected to my ADSL modem/router.
Symptoms:
Every now and then (couple of time per day) I'm not able to access the Internet. The internal NW is still OK: I can access both of my routers. When this happens I see that iStat Pro shows that the External IP is being updated. Which is strange, because my laptop which is connected to the same USR router is still able to continue to access the Internet at the same time. So no problem with the external IP address. I checked the modem/router at the time of the drop-out, but that was fine.
I tried using the same UTP cable to connect my laptop iso iMac, still no problem. I tried it connecting the iMac wireless to my router, still the same issue.
I returned the iMac to the service center for having it analyzed, but as expected they didn't experience any issue.
Is there anybody else with the same problem? At first I thought it would be a faulty NW i/f or driver, but as it happens with both the wired/wireless i/f I should think of something else.
Thanks.

Hi Gringeiro,
Are you using WEP or WPA wireless security on your router? I would recommend WPA2 with AES, well, if you want to connect it wirelessly. Also, it will help if you set a static IP address on the printer. You can do this by typing the printer's IP address into the address bar of your browser. Select the Network tab, then look for IPV4 under the Wired or Wireless section, depending upon how you have it connected. There should be an option to "Suggest Manual IP". If not, type IPCONFIG from the command prompt (Start/Run cmd) to get your Subnet and Gateway addresses.
If I have solved your issue, please feel free to provide kudos and make sure you mark this thread as solution provided.

Remote can't find iTunes on mix wired/wireless network

I am trying to control music from a iMac running iTunes using the iPhone Remote app. I've previously done this successfully with a wireless only network (using the Airport Express wifi to join my existing wifi network etc).
However, since introducing D-Link Homeplugs into my network, I am unable to 'see' the iTunes library from the Remote app when I connect wirelessly to the airport express.
My hardware is configured as follows:-
*Netgear Router (wireless disabled) -> Homeplug power network -> iMac running iTunes*
And elsewhere on the Homeplug network, I have:
H*omeplug power network -> Airport Express [set up as wireless access point]*.
If I connect the Express to the iTunes machine directly - leaving the wireless access details the same - it all works fine. If I move the Airport Express and reconnect over the Homeplug network, the Remote fails to 'see' the library, although I can still send music over the network (using the iTunes interface on the iMac) to the remote speakers.
My network uses the router as a DHCP (range 192.168.0.x mask 255.255.255.0), Airport Express is connected to Homeplug ethernet with a static IP (in the same range) and provides wireless access (unsecured for now while i get this working). The iMac has a static IP (in the same range). If I swap the iMac for a PC (XP - using DHCP from the router for IP), I get the same result. If I use an iPhone network application to view the network (connected by the wifi access point on the AX) then I can see all the machines on my network as I would expect.
To reiterate, if I cable this network directly (either AX->iMac or AX->hub->iMac) then it works. As soon as I go AX->Homeplug power network->iMac then the Remote app loses sight of the library.
I wouldn't expect any firewall on the wired->wireless networks on my router (a Sky branded Netgear 934g). I also didn't think that the Homeplugs would block.
So does anyone have any ideas why the Remote application loses sight of my iTunes library when connecting via Airport Express cabled into a Homeplug ethernet network ?
Thanks for any help because I miss my music
cheers,
Tim

Can you use a roaming network and wireless extender at same time?

Greetings community - I've been struggling with an attempt to extend my wireless network for some time now. Please forgive my ignorance on the topic - I realize how 'simple' this is for many of you. Let me summarize:
What I have functioning:
1. Comcast telephony modem
2. 5th gen Airport Extreme as main wireless router connected to modem via Ethernet (corner of floor 3)
3. 2nd gen Airport Express as wireless extender (hooked to a stereo on floor 2)
What I want to accomplish:
1. I have poor wireless signal on my sun porch (corner of floor 1 opposite side of building as modem)
Extra equipment I have:
1. Another 5th gen Airport Extreme
2. Another 2nd gen Airport Express
What I have tried (and failed at):
1. Initially I set up the second Airport Extreme as a second wireless extender and placed it at a further point away than my first wireless extender. I quickly realized that set up does not function appropriately and one cannot connect to the further extender (I read about that on the apple forums).
2. I tried placing the second Airport Extreme in a different part of the house at equal distance from the main router as the first wireless extender. It's capability to extend was minimal if any.
3. I tried connecting the Airport Extreme to the main router via an Ethernet cable with the hopes of creating a roaming network (which I read about on the apple forums). I would have to come up with a way to run the Ethernet through the house but I'm willing to cross that bridge later. Once I got that set up, the 2nd gen Airport Express which was previously set up as a wireless extender is no longer recognized. Argh!!
Questions/Theories/Suggestions:
1. Is it possible to have a wired extender (via Ethernet) function at the same time as a separate wireless extender all connected to the same router? If so how do I do it?
2. I thought about keeping Airport Extreme #1 wireless connected to Airport Express #1 and call that Network 1. Then plug Airport Extreme #2 directly into the modem to create Network #2 and use Airport Express #2 as wireless extender. When I tried plugging both Airport Extremes into the modem, they both stopped functioning.
3. Do I get a second modem to put somewhere else in the house and use Airport Extreme #2 and Airport Express #2 in that fashion? My guess is Comcast will try to charge me a separate internet access fee to do that (boo!!).
I know there are a lot of brilliant folks out there. I'm sure someone can read this and see the 'obvious errors' in my ideas and attempts. I'm certainly open to new suggestions as well.
Thank you in advance for your time and advice.

Is is possible to rename the AEx 2 a different network name from the AEx1 and AE 1 (even though they are all connected to each other)? And say it is possible, would that potentially preventing the jumping?
No, in extend wireless the names must be the same..
However since you are creating a network on AE2 which is extended by AEx2 then you can indeed use a different name.. but it must be both,, AE2 and AEx2.
2. Even more crazy - if I did (could) give the AEx 2 a different network name, could I use my AE 2 as a wireless extension to that second network? Or is this just getting out of hand now?
You have lost me now.. there are ways and means.. but let me recommend a better solution.
Use EOP (homeplug in US) adapters if you cannot run ethernet. Multi-storey houses where you have heavy concrete construction are never going to work well with wireless alone. You are much better getting ethernet properly installed (which is the only 100% guaranteed method).. or buy a set of EOP adapters and give them a try.. they work in some cases and not others.. but better than wireless when they do work.
Otherwise I think you need higher power wireless routers.. but I can suggest you do the setup in a more controlled manner.
In other words do not use auto as per the airport utility.. use very short wireless names, different for both bands.. and fixed wireless channels.. then test which band works better.. Then you can do a link.. which will be slow but might give you better performance.
So..
Link1 Main AE1---- AEx1 This is wireless extend.
Link2 AEx1--ethernet--AE2. AE2 is in bridge mode and is also set to create a wireless network. (Use different wireless name here to prevent confusion).
Link3 AE2-----AEx2 Second wireless extend.
This overcomes the Apple limitation on multiple extends. It is not great setup but might get wireless to where you need it.. And better speed than you can get now.
NOTE>. I would personally never do this.. I will run ethernet forevermore.. having tried and tried in various places and using all kinds of equipment.. my conclusion is.. wireless is not suitable.. unless you can get enough signal in from one AP.. everything behind it must be ethernet.
It is much more expensive in some cases.. but ethernet works.. nothing else can be guaranteed to work.

FAX server in 10.5 server and across subnets

We can use 10.5 Server as a FAX server. Since I got this working a while ago, it has run reliably.
This is how we are doing it. Hopefully this will help others get it working too.
Our server: 10.5.2, Pro Intel 2x2.8 quad with a USB Apple faxmodem attached to the front USB port plugged into a standard phone line. Print service is set up and running and happens to be serving printers for us. Once the FAX seemed to get confused and not receive or send. I unplugged the USB fax, plugged it back in and it was fine again.
At the server I opened a text edit document and told the server to fax from Print > PDF > Fax PDF. A fax printer was automatically created on the server. While the fax was printing I told the printer in the Dock to "keep in dock." Opened that fax printer, choose "info" icon in top of window and renamed the fax from "external modem" to a new name so that it would be easy for our staff to use and find it. The server now has a fax on it. As anyone who has tried this has found you CANNOT edit the FAX from ServerAdmin. You can now see it as a queue with the new name it was given but editing it not possible from SA.
At the server still in System Preferences > Fax and print > the new fax appears in the bottom of the printers list under "Faxes." Select the fax. Select "receive options" and set up how the fax is to receive and place received faxes. Ours go in to a folder in a share point which is available and automounted to everyone on our network so anyone, anywhere can get the incoming faxes. The next point assumes that you will do the same.
In 10.4 and once in 10.5 I had to delete the fax manually from System Preferences and recreate it as above when everything seemed to stop working and unplugging the modem and rebooting the server did not fix the stall. As long as everything is named exactly the same when you recreate the fax, no other changes or repeat of what is described below was needed.
For each of the users in our OD:
Tell them each to do the following: Open Applications > Applescript > Folder actions setup. Check off "enable folder actions," hit the + under the left box and select the folder in the share where the faxes are being received. Now select the fax folder in the left and hit the + under the right box and choose "add - new item alert." Save as necessary. The users who do this will now get notification when a new fax arrives and is deposited by the server in the Fax folder.
Now to get the fax to the clients to fax out on. The following will also get all of your shared printers onto any off server's subnet clients. For us the fax did not even show up in local subnet clients as printers usually do. So I kept working and eventually came up with the following:
Our network:
Main location 192.168.1.* server is here.
Remote locations connected via Verizon T1 and routers with no firewalling
192.168.2.*
192.168.3.*
Our client machines :
Intel white iMacs all running 10.5.2 with no special software for faxing. Our clients are bound to and controlled by our server.
I have been trying to get our server to serve the FAX across our 2 remote subnets since 10.3. With the newer CUPS coming with 10.5 and Apple now owning it I hoped that there would be an easy solution to get non local subnet computers the ability to see shared faxes and printers. Sent a forum question and got the following which was great news

The simplest way is to change the "Allow from @LOCAL" lines to be
"Allow from all". You can also use the web interface and check the
"Allow printing from the Internet", which does the same. If you
don't want to open up that much, just add "Allow from" lines for
each subnet.
Once you make this change, *do not* toggle the printer sharing box,
or you'll have to make the changes all over again.

Michael,
Thanks for the reply, sounds like you have my solution. Small problem, upon selecting "allow printing from internet" in the web interface and committing the changes, the server restarts and the check box is empty again. In quick tests, the other options can be turned on and off as you would expect. Is there something particular to the Apple 10.5.1 install that would not permit internet printing or not permit this change?
I think the check box state in the web interface is a known bug in
CUPS 1.3.4.
I used the web interface for cups on the server and manually added the networks as described by Michael above. I don't know if it is required but I restarted the server. Open > Safari > browse to localhost:631 and you will get the CUPS web interface. The CUPS web interface is available on servers and clients. You can also browse to an IP or FDQN:631 to get the web interface from a receptive other machine.
The server was now supposedly ready to accept "browsepoll" requests from clients. I had played with this before so I was somewhat familiar with what to do next. Essentially each client needs to be told to contact the server and ask it for its printers. That is what browsepoll does in CUPS.
At the client, be logged in as an admin user OF THE CLIENT. Using Terminal and a text editor, edit as root /etc/cups/cupsd.conf
A few lines down look for:
# Show shared printers on the local network.
Browsing On
BrowseOrder allow,deny
BrowseAllow all
After that we added :
#*added by Erich*
BrowseProtocols all
BrowseRemoteProtocols all
BrowsePoll yourserver:631
BrowsePort 631
#*added by Erich*
where "yourserver" is either the IP address or FDQN of your server as seen by the client machine.
Save the file. Reboot the client. The CUPS system on the client will now ask your server CUPS system for its printers directly and repeatedly until it gets them. If it does not get any you will not be notified in anyway other than log messages on the client, see Console > /var/log > cups to review them, and the fact that you don't get your server's printers being available on the client.
This last piece came from a discussion started by Alessandro Dellavedova : check the starting post
http://discussions.apple.com/thread.jspa?messageID=5702731&#5702731
If you go to Safari > Localhost:631 on the client, CUPS should now see both the printers and the fax which are being hosted by your server.
Here's the fun part for me, with no additional playing I was now able to see the fax we created long ago in the print dialog printer list. You do not have to go to Print > PDF > Fax PDF, you can but do not have to. Just select the fax from the printer list and the dialog changes to fax appropriate options. Now we were able to print any document to the fax directly.
Odd behavior I have yet to figure out. I do not see the fax in the System Preferences > print and fax pane on the client machines. However, I can now fax through our server from all of our clients no matter what subnet they are on.
Making the same additions to the cupsd.conf file on remote machines which VPN via the internet to your network will get them the printers and fax in the same way. I do this with a powerbook and Imac from home so i can print at and fax from work.
This is what I did to get it working for us. Hope this helps.

This is Great! Thanks a lot, this was exactly what I was looking for!

Sharing across Subnets

Hi there,
I work for a company where we have a wired lan and a wireless lan.
The wired lan is 192.168.97.* and the wireless is 192.168.98.*
When connected to the wired LAN, we are able to see all shared machine who are also on the .97 subnet.
When connected to the wireless LAN, we are able to see all shared machines who are on the .98 subnet.
When on the wireless, we are able to ping all .97 addresses on the wired LAN no problem.
However, I need the .97 shared machines to show up under 'shared' within finder when users are connected to the .98 network (wireless)
Can anyone point me in the right direction as to how I can do this ?

Buy more expensive routers :-)
If you are using consumer routers, you are limited in what you can do.
The easy thing would be to stop using the 192.168.98.* subnet, tell the WiFi router to become a "Bridge" and share the 192.168.97.* subnet. Depending on the router, this is done by an explicit "Bridge" mode setting (Apple Airport Extreme), or in some cases it is disabling DHCP server on the router, or some routers require you to disable DHCP and NAT servers. But once you do that, it disables routing and turns the device into a "Bridge" that shares the ethernet subnet with WiFi devices.
Of course if your company is so big that you have more than 200'ish devices including routers, networked printers, mobile devices, computers, etc.... just using a single subnet driven by a consumer router may be an issue.
Also if you have that many devices a consumer router may have issues moving all that data.
There are consumer routers that allow you to replace the firmware with an open source router firmware that would give you more flexibility in configuring your subnet, such as changing the router's subnet mask from 255.255.255.0 to something that allows more devices, such as 255.255.0.0, but again, now your router needs to have the horse power to handle all the devices.

I-Series chipsets netbooting across subnets

Hello all,
Is anyone having issues attaching to tftp served netinstall images across subnet's with i-series hardware? Here's the situation, the netinstall.dmg was created form a factory build core i7 macbook pro mid 2012. Imaging on the same subnet as the server works fine for all hardware type. Older hardware, for example core2duo or xenon's, can image iacrros subnet's and on the servers subnet without issue. The problem only appears to occur when imaging an i-series device across subnet's. Anyone have any ideas? Could really use some help here.
Thanks

Hi Steve,
While in most sites I have them in the same subnet there is a site where they are in 2 subnets. I was hoping to be able to make the roam seamless. If you have to disable and enable the wireless or perform an ipconfig /renew it takes away from the seamlessness :-).
Any suggestions would be welcome. However, I can understand what Scott is saying also as that is how it currently works.
The environment consists of all Anonymous AP various Aironent 1200 series, i.e. 100, 1250, etc.
