Wireless printer networking

I love the printer but lately it decides that it is going to be my network and overrides my inhouse wi fi.  Sometimes its not discoverable by my tablet. 

Who is your internet service provider?  So you say that your printing is intermittent? it goes on and off

  • Wireless printer network

    My cell phone and tablet sometimes lock onto the wireless printer network instead of the Internet wireless network in my home. This occurs randomly and it has nothing to do with printing. I have to manually chose the correct network. Any suggestions to configure the printer so the phone doesn't pick that nerwork automatically? The phone is a LG G3 from Verizon.

    You need to disable Wireless Direct in the printer.

  • Wireless Printing/Network Issues

    Here is our dillemma.   We have an iMac running on OS 10.6.8, a Lexmark X4650 wireless printer and a PC.  The iMac, PC and work computers and ipads as well as the printer all connect to our network.  I can print from the PC but I can't from the iMac.  I have reset the printers on the iMac.  I have unplugged and plugged back in the modem and router. I have pinged the printer from the iMac, and have found all of the ip addresses, on all devices the first three sets of numbers are all the same, and the last 3 digits are different on each device (printer, pc, imac).  When trying to print from the mac, I get the "unable to connect to printer", "device is busy", or "printer is off line". 
    Any help of information on solutions would be grateful.
    Thanks!

  • Wireless printing - network host is busy/unreachable?

    Hi everyone,
    We installed a wireless (Lexmark X9350) network printer on our Airport network (behind ADSL + router with DHCP functions enabled).
    The printer software installation finished successfully but gave a warning that the printer had not been added to the printer list and could/should be added manually. After having done this, wireless printing to the X9350 doesn't seem to be working: error: Network host is busy, unreachable, .... The same occurs on 10.4 (Tiger) and 10.3.
    However, wireless printing from 2 PCs (WindowsXP) on the same wireless network works ok. Printing test page with USB cable attached to the Mac seems to be working as well. Any tips how we can get this wireless printing working for the Macs?
    Thanks,
    Guy

    I meant specifically, after clicking ADD and then clicking More Printers, is there a Lexmark proprietary protocol choice that you used - something like "Lexmark network inkjet?" That will be the only way to add the printer - not IP printing.

  • Wireless printer network w/o wireless internet?

    I got a new printer and have it wired to my iMac and want to wirelessly connect it to the Mac Pro. The printer is capable of wireless, but it asks for an SSID. Can I set this up with only my two computers without involving wireless internet? (Does my computer have an SSID, or is that exclusive to wireless ISP networks?)
    Thanks for any info!
    -Doug

    Hi
    SSID (Service Set Identifier) is the name of your network/WLAN. You don't need to have an internet connection, you just need to have a wireless network.
    You can create an ad-hoc network using your Mac, but I don't know how your printer would go connecting to that, seeing as its mainly used as a computer-to-computer network.
    You may be best to keep it connected via USB to one Mac, and use Printer Sharing (System Preferences -> Sharing) to share the printer over the network, but again, you will need a wireless (or wired for that matter) network connection for this to work.

  • Help me enable a wireless print network!

    How can I connect my (2007)airport extreme to Netgear N300 router that is connected to modem? I want to do this bc my cannon MP460 printer will then print wirelessly.  I had this setup at my house but recently moved in my parents duplex and want to have my own network.

    Connect an Ethernet cable from a LAN <--> port on the Netgear router to the WAN "O" port on the AirPort Extreme and configure the Extreme to "create a wireless network".

  • Will a late '09 Imac support a wireless print network with a 16/600 laser writer laserwriter?

    I had a wireless network set up with a Quicksilver and a Macbook Pro with a 16/600 ps laserwriter with a transponder plugged  into an airport extreme. The Macbook pro would only print when the Quicksilver was on. We replaced the Quicksilver with a late '09 imac 3.6 G and 21.5" screen. We used migtation assistant. Why can't I print!
    Harold

    Appletalk support has be dropped in OS X as of Snow Leopard. However if you can get the IP address of the printer then you should be able to add it as an IP printer. Because the printer is so old I would have no idea how to get it's IP address however  you can look in the printers utilities to see if it can print a status or configuration page.

  • Wired & Wireless Printing & Networking

    I have an iMac G5 , a Powermac G5, an iMac G3 and 2 Powerbooks in my house, all connected to the internet.
    The 2 imacs are connected to a 3rd party router via ethernet, and the Powermac G5 & the laptops are connected via airport express which is connected to the 3rd party router.
    The laptops and the powermac are all on one network, and can share files, music and printers, but the 2 imacs seem to be on thier own seperate network, and can't 'see' the wireless computers. is there any way that i can get all of them onto one network and share printers,music and files between all of them? any replies appreciated, thanks. All computers are on Tiger apart from the G3 imac which is on 10.3.

    Your problem is that your computers are on two logical networks. The ones connected to the router directly are receiving their TCP/IP configuration from the router and the ones connected to the Airport Express are receiving their configuration from the Express.
    What you need to do is stop the Airport Express from acting as a DHCP server so that all computers receive their configuration from the router. To do this login to the Airport Express using the "Apple Airport Admin Utility" now disable the "Distribute IP addresses" option. Once you have done that you may need to reboot the two computers connected via Airport to ensure they receive the new TCP/IP configuration from the router.

  • Brand new Mac user, needs help getting Mac onto Wireless Print Server

    Ladies & Gents,
    After much struggle with PCs in the last two weeks I finally broke down and bought a MacBook. I'm very happy with it, but I am having issues getting hooked into my office's wireless printing network.
    The printer is an HP Color Laserjet 3600n and we're set up with a D-Link DPR 1260 router. I've tried just about everything I know, and even our much-more-qualified-than-I resident Mac user is unsure how to make this work.
    I will continue to search the forum, but I would appreciate any help. I should be off and on throughout most of the day. Thanks!

  • Wireless printing with airport express/extreme?

    i'm trying to figure out how to use either an express or an extreme (I have both) as a wireless print network of sorts. In the past I hooked up my modem to the extreme along with my printers, and was able to connect wirelessly to my computer; thus, wireless printing. i have since changed to google fiber (including that just in case that's part of the issue), and my modem/router is on a different level of the house than the rest of my computer setup, and i don't think it can be moved. All the solutions i've found require a computer to be directly connected to the modem/express for the initial setup, which isn't possible in this case as i don't have a laptop, just a desktop. Any suggestions would be much appreciated!

    It helps if you use specifics.
    Are you talking about a USB printer?
    What is the google modem router??
    How and where do you hope to place the airport and printer? ie will it be plugged into the main router by ethernet?
    There is no problems doing the setup over wireless.. as long as wireless reaches the computer. There is also no problem manually setting up the airport router in total isolation from the network.. once  setup you can place it back into the network.
    Typical method of manual backup.
    Airport Utility shows "unexpected error - please try again" when connecting to Time Capsule

  • Using the D-Link Router DIR-655 in order to set up wireless printing

    Hi, I have a newly purchased D-Link Router, DIR-655, and it had a USB port which enables NAS. However, I was wondering if I would be able to set up my printer, an HP P1005, in order to print wirelessly. I plugged in the printer's usb cable into the router and I refreshed my airport. It found a "printer server" and I connected to it. However I'm now oblivious to the next step I must take in order to set up this wireless printer network.
    Any help/advice would be awesome
    Thanks.

    That is of course possible. One hears that D-Link do not always play well with Macs, although my ADSL modem/router is fine. I connect my HP printer using Apple's Airport Express (that has a USB port) and maybe that is part of the installation of that device.
    Have you turned on the printer sharing features in System Preferences >Sharing or even the Windows Printer.
    You mention the Port number: is the firewall allowing access to that port?

  • Wireless and network printing transcript for Meet the Experts

    On March 16th, HP hosted its first online chat event on wireless and network printing. Below is a transcript of that session.
    I am in the process of planning the next chat event. I would love to hear what topics would interest you, what day of the week and time is best for you, and if you think an hour is too long.
    So, if you get a minute, please let me know.
    Here's the transcript:
    SiobhanF-HP: Welcome! Cameron, Craig, David, and Jim are ready to tackle your questions.
    SiobhanF-HP: Just to remind you if you want to ask a question, you must be a member of the HP Support Forums. If you want to join, go here https://passport2.hp.com/hppcf/createuser.do
    nc256: Do I need a wireless router to hook up my wireless printer?
    CameronL-HP: No, but most people will want to do it this way. You can use a feature called an ad hoc connection to avoid using a router, but it is only covered under an older standard that is slower and less secure. Also, without something to route traffic between the local network and the internet, you cannot get an internet connection. Using a wireless router makes setting up a wireless network easier, and it will generally make the network work better too.
    jest1: I've seen some hardware in stores for a "print server" hardware device that attaches to a network. Is this something that I need in order to run a printer over a network?
    CraigB--HP: Not if you have a printer that has a network connection built in. Many models of HP computers are ready to be connected directly to your wired or wireless network.
    katiepage: How can I print when I am using a VPN?
    DavidH-HP: VPN connections generally hide the rest of your home network to increase the security of the VPN connection. A printer on the network isn’t a security threat but the VPN doesn’t know that. It just hides everything just to be sure. That means that when a VPN is active you need some way to connect to the printer other than your home network. Bluetooth, USB, and even printing to a thumb drive and plugging that into the printer are all ways of getting your print job to the printer that don’t go through your home network.
    SiobhanF-HP: If you have specific product questions, the more information you give us the better we will be able to help you. Getting your exact model number; any error messages; a description of your wireless network including what kind of security you have, what wireless-devices are connected to your network, and your IP address will go a long way to helping us answer your question.
    MelissaP: Why would I want a wireless printer?
    CraigB--HP: The main advantage of a wireless printer is the ability to place the printer somewhere in your home or office even if this is not near your router or computer.
    Deltan: What is the maximum distance I can have between my router and my printer?
    CameronL-HP: It does depend on your environment. Without interference about 25 feet. Walls and floors and other objects can reduce this. The types of walls are important. For example, mirrors and outdoor walls will greatly reduce the indoor range.
     jest1: Is there a preferred wireless router type or brand for wireless printing compatibility? We are using a Linksys 802.11g router in my home.
     JimB-HP: In general, any wireless-router from a name brand manufacturer that has been Wi-Fi certified is compatible with our printers (look for the Wi-Fi logo). We use Linksys in our lab with great success.
     nc256: Are there any digital cameras that can send directly to an HP wireless printer for photo printing?
     DavidH-HP: Many printers support a feature called Pictbridge. If the camera and printer both supports this feature, the camera can be plugged directly into the printer to print photos. Or are you asking about printing over a network connection?
     KevinW: I keep hearing that you shouldn’t use default settings for a network. Why?
     CraigB--HP: There are three reasons not use default settings: First, wireless-routers do not have any wireless security enabled by default. Second, you will be using a common network name in which case you may connect accidentally to your neighbor’s network. Third, your wireless-router is accessible by inadvertent guests who may change the configuration of your wireless-router without your knowledge or use your internet connection without your permission.
    Bodie08: I have an HP Lan attached printer and Windows XP on my home network. Is there a known setting (Firewall/port/other) or patch to address the issue of hpqtra08.exe hanging on Windows XP Shutdown? A number of us in the forum have identified this issue. Thanks!
    DavidH-HP: This problem has been seen in the past but there were attempts to address it. Have you checked to see if there is a later release of software available on the web? (hp.com)
    ZhuLee3: How old is wireless printing technology? I noticed all the experts have around 20 years of experience with it, was there wireless 20 years ago?
    JimB-HP: Wireless printing first appeared with the introduction of the 802.11 standard in late 1990's. HP has been making wireless printers since 2003.
    lpeterson123: What makes wireless so flaky at times?
    CameronL-HP: There are lots of reasons. Wireless signals are affected by distance, walls, metal objects, and other wireless devices like cordless phones. However, most of the problems seem to be from how the network or how security software is configured, and these can also cause things to fail only occasionally or in certain situations. Having a good wireless connection between a PC and printer involves several hardware devices and lots of software made by different companies that all have to work together; if something is not quite right in any of these things then the whole solution looks flaky.
    Bowman16: I use a Mac, are there any features that would not work if I was to set it up for wireless use
    DavidH-HP: All the features will work on a Mac if you install the full HP software solution.
    jest1: Thanks for the answer on the router question. The next question, then, is to ask what would be a recommended consumer-grade wireless-enabled printer (or series) just so I can start my research.
    JimB-HP: Any of our Photosmart or Officejet wireless printers will work with Wi-Fi certified wireless-routers. Our price points really have more to do with how much printing you do. In general, our more expensive printers cost less per page than our less expensive models.
    Bodie08: Why would I choose "spooling" on my PC over "direct connect”?
    CraigB--HP: In general, spooling allows you to use your program sooner than printing directly.
    ZhuLee3: Jim: What is it like to be an "HP Printing Expert"? What kind of stuff do you get to work on, on a day to day basis?
    JimB-HP: I really like my job -- I've always been a radio enthusiast so working on 802.11 technology is really a dream job for me. I'm also fortunate to work with a great team here in Vancouver, WA. More importantly, I like designing equipment that people use in their everyday lives.
    TEACHER1: Recently I changed routers, now I am unable to print wirelessly, even though the SES and wireless network light are steady on my Deskjet 6980 printer. What is the solution? Thanks.
    DavidH-HP: The wireless light indicates that the radio is on but does not indicate that the printer is connected to the network. First check that the printer is connected to the network by printing a network configuration page from the printer.
    AgentRed: I get my internet with a Verizon wireless broadband card. Someone told me that wouldn't work with a wireless printer. Is that true?
    CameronL-HP: Our wireless printers use the 802.11 b, g or n standard which is not compatible with the wireless cellular standard. It would be like trying to connect to a wireless network using Bluetooth. They are different wireless technologies.
    DavidH-HP: Regarding the Verizon card, it is true that you cannot connect the printer over the Verizon connection, but as long as your laptop has Wife you can print to the printer over WiFi at the same time that the Verizon connection is active. This should not be a problem.
    jest1: Is there a "minimum" internet connection that is recommended for wireless printing? We live a bit far from the DSL CO so our connection is sometimes flaky. I would guess that incoming speed shouldn't affect my local wireless LAN but I want to ask it anyway
    CameronL-HP: There are 2 parts to your home network. 1 is your wireless router which manages your local network equipment, then your network connection to the world wide web which your DSL provider gives you. The connection speed of your local network is not affected by your internet connection speed.
    Bowman16: Are any HP printers 802.11n? I do not want to add an 802.11b,g to my network and cause it to slow down.
    JimB-HP: Currently, our printers comply with the 802.11g standard. We are investigation the emerging 802.11n standard.
    ZhuLee3: Will there be a transcript of all the questions and answers from this chat available for viewing after the session? I think I missed some questions at the start.
    SiobhanF-HP: The chat event begins when you joined. Sorry that you can't see what was said before you joined. I hope to have transcript posted tomorrow or on Wednesday at the latest.
    nc256: Where is the future of printers headed? Does HP have any interesting plans with printing technology? And what’s your opinion on whether or not color laser printing will ever approachthe photo realism of ink jet color?
    JimB-HP: The future of HP printing will be characterized by wireless connectivity to not only computers but to mobile internet devices. In fact, as mobile devices become smaller (think phone or netbooks), the need to print from your mobile device might become more relevant.
    jest1: Am I able to print from my iphone to a wireless printer?
    CraigB--HP: You can print photos from your iPhone to HP wireless printers and it works great in my experience. Go to http://www.hp.com/go/iprintphoto to get the details.
    TEACHER1: Thank you. I printed a page. It shows that wireless is disconnected.
    DavidH-HP: Then you just need to input the wireless settings from your new router into the printer. If your printer does not let you input the settings from the front panel, you can use the CD that came with the printer or downloaded from hp.com to configure the printer again ( look for the option to "add a device" ).
    ZhuLee3: Question about security... if I get a wireless printer, what’s to prevent other people within range of my printer, from adding it and printing documents? How is this configured on the actual printer?
    JimB-HP: The simplest way to secure your printer is to enable WPA-PSK security for your wireless network and to use a security pass-phrase that is at least 12 characters long. This configuration is very safe from intruders for the foreseeable future.
    CameronL-HP: It' is also a good idea to use a unique network name, also called an SSID.
    carolj: I have a photosmart C7180 and I have it hooked up to my laptop (windows vista) when the setup completed the printer was put in networking instead of printers and I cannot access it or move it out of there. What do you suggest?
    CraigB--HP: You might need to uninstall and reinstall. Before doing this, make sure your get the latest driver from the HP support at: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=1153754&lc=en&cc=us&dlc=en&lang=en&cc=us This is also where you can get a copy of the instruction book.
    wizll: Hi, I haven't done much research in wireless printing, but I'm interested as I currently have my printer set up the old fashioned way where it's connected to a networked PC, but if the PC is off I can no longer print, which is obviously inconvenient. Do hp wireless printers have a web gui you can connect to once it's on the home network, or is it simply all done from the printer's interface. I've seen some old wired network printers that only use the printer's ui and that seems like a clunky use.
    DavidH-HP: Yes, the HP printers which have networking built-in have what we call an "embedded" web server which allow you to configure settings, check status, and have many other features; on some models you can even scan using the embedded web server.
    nc256: Jim: Will color laser printing ever reach ink jet quality for photos?
    JimB-HP: While never is a long time, inkjet printers will, for the near future, output higher quality photos.
    katiepage: If I'm at home, connected to my office network via VPN, can I access my office networked printers?
    CraigB--HP: Yes, when you are connected to the office VPN, you can print to your office printers. However, you will not be able to print to your home networked printers while you are connected to the VPN.
    jest1: If a friend comes over to my house with their laptop and needs to print something, are they able to do this just by authenticating with my wireless LAN (assuming I have a wireless printer set up)?
    CraigB--HP: In addition to authenticating to your network, you friend will also need to install the printer driver for your printer.
    jpszambelan: Is there a wireless USB device of some kind I can connect to my printer if there is no network connection already built in?
    JimB-HP: HP sells an accessory that adds Wi-Fi capability to your USB printer (see http://www.shopping.hp.com/product/printer/inkjet/wireless/4/accessories/Q6236A%2523A2L) Also, many higher-end wireless-routers allows USB printers to be connected to them to allow sharing of the printer from the network. Note that this solution often limits you to just printing and not scanning from the network.
    rockwoodchev: It seems that my computer can find my printer, but my printer can't find the computer, so that "Scan to computer" won't work. What do I need to do in order to fix that?
    DavidH-HP: This can be blocked by security software running on the PC (such as a personal firewall). Make sure that your firewall is configured to allow communication on your local network. You can also unblock specific ports, but the easiest way is often just to allow communication on the local home network. The specific setting varies from firewall to firewall.
    SiobhanF-HP: We are nearing the end of our chat session. We only have time for 3 more questions. If we did not get to your question, please post it on the Networking and Wireless board in the Printers and All-in-Ones forum. http://h30434.www3.hp.com/psg/board?board.id=Networking
    SSPatrick: Is it possible to print wirelessly to the same HP printer using both a PC and a Mac?
    JimB-HP: Yes -- I do this in my home. I have both Macs and PCs on my network without any trouble.
    Bowman16: Any plans to do this again?
    SiobhanF-HP: Yes we are.
    ZhuLee3: Do all of the experts hang out on the HP community? Will we see you posting there after this?
    DavidH-HP: Oh yes, whenever time permits. In addition to trying to help people, I learn things too.
    JimB-HP: I'm known as Wi-Fi-Guy on the support forums. I hang out there often helping where I can. It helps me be a better designer.
    CraigB--HP: I monitor the forums looking for problems to take back to the development lab for investigation. To date, I have only posted one reply.
    CameronL-HP: I haven't been involved in the past but expect to be more involved in the future.
    SiobhanF-HP: We only have time for one more question. If we did not get to your question, please post it on the Networking and Wireless board in the Printers and All-in-Ones forum. http://h30434.www3.hp.com/psg/board?board.id=Networking
    ZhuLee3: Thanks for setting this up!
    SiobhanF-HP: The transcript will be posted on http://h30434.www3.hp.com/psg/board?board.id=Networking
    TEACHER1: Thank you all for conducting this session !!!!
    jest1: Is there an OS limitation to print wirelessly?
    JimB-HP: All the OS versions supported by the printer as supported wirelessly. In general, we are compatible with Macs, Windows and Linux.
    SiobhanF-HP: We are ending the chat event. Thank you for coming. We hope you found it worthwhile. I will be posting a transcript of the event in the Networking and Wireless board in the Printers and All-in-Ones forum. We will be hosting future Meet the Experts chat sessions on a variety of topics, so please tell us what you thought of the event and how it could be improved. http://h30434.www3.hp.com/psg/board/message?board.id=Feedback&thread.id=525

  • Wireless printer disconnecting from network

    Hello all,
    Here is my problem.  I have a new HP 3510 set up as a wireless printer on my home network.  I have three computers, two wired and one wireless.  I have a netgear router for 3G air card.  I can connect my printer to the network initially.  I can print from any computer, initially.  I can even use ePrint.  The trouble is that the next day, when I fire up any of my computers that printer is no longer on the network.  I have upgraded the router firmware, and the trouble seems to be there.  When I power cycle the router, everything is connected once more.  I have set a static IP on the printer.  Furthermore, and have tried setting the printer as a static IP within the router.  I am now at a loss.  I have read about setting the DHCP range on my router outside the printer IP.  Would this even make a difference?  Since I am not sure what is happening, I do not know if this will help any.  It acts like either the router or the printer are going into a sleep mode or something, however, my phone is also connected on the network, and when I get home it immediately connects.
    Thank you in advance for the help.
    FYI: the two wired computers are XP and Win7.  the wireless is Vista
    I have wpa-psk + wpa2-psk set for my router security.  Have not tampered with the router firewall, but since the printer connects initially, not sure if that would be the cause.  I have set the printer IP well above anything that has been used by any other networked hardware.

    Hi, unless you reserve the static IP in DHCP it is best to assign a static IP outside the DHCP range.

  • Can I connect a wireless printer to two wireless networks

    I searched and couldn't find an answer to this exact situation. The answers to similar questions didn't seem to work.
    Can we share a wireless printer over two wireless networks without adding hardware or changing the wiring or doing complicated software modifications?
    Here is my set-up:
    Cable Modem> Linksys Wireless Router “N” on the first floor > older AirPort Extreme “G” via ethernet cable on second floor > Laser Printer via USB Cable on the second floor, plus an AirPort Express to extend the area on the second floor. We have 2 MacBooks and 1 MacBookPro that connect to the internet via either of 2 wireless networks. Generally, for better connection, you choose “N” if you are on the first floor and “G” for the second floor.
    Currently, if you want to print to the USB Printer, you just select it in the print dialog box. It does not matter if you are on Network “N” or Network “G.”
    We just added a new wireless Printer that’s on the first floor. (No, I didn't read the directions, the printer screen said if there is a W?? button on your router, press it. I did and it automatically connected to the “N” network. It also has its own email address for printing without a computer, but that still doesn't solve this question.)
    If you want to print to this printer, you must first change the computer’s AirPort setting to join the “N” network. If you don't, you still get the print dialog box, but eventually you will notice that nothing happens. The document just sits in the Printer’s queue.
    Is there a way to get a computer on the “G” network to find the wireless printer on the “N” network without first changing networks?
    Remember, it automatically finds the USB printer that is plugged into the “G” network router.

    It used to be that if you wanted to wirelessly extend the range of a network, you'd have to set up a WDS. (WDS = Wireless Distribution System.) There was no "Extend a wireless network" option and no "Allow this network to be extended" checkbox—you'd have to fill out lots of WDS information yourself. It was sort of a pain.
    Then, with the 802.11n AirPorts, Apple introduced the "Extend a wireless network" option, greatly simplifying the setup process. It accomplishes the same thing as a WDS, but it's easier to set up and has less overhead. However, it can only be used if every AirPort in the wireless network supports 802.11n.
    Your Express may support 802.11n, but your Extreme is older and does not. So "Extend a wireless network" won't work for your network. That's why you got errors when you set the Express's "Wireless Mode" option to "Extend a wireless network." Instead, you'll have to do things the old-fashioned way* and configure the Extreme and the Express to be part of a WDS. Your network will still work as desired: the Express will rebroadcast the signal from the Extreme, and clients will connect to whichever station has the stronger signal. It's just that you'll be using the older WDS technology instead of the newer "Extend a wireless network" feature.
    "Join a wireless network" is something different entirely. You'd use it if you wanted to connect to a network but not rebroadcast it. This could be useful when, for instance, your main router isn't an AirPort but you want to use AirTunes. In your case, however, this option wouldn't be very useful.

    *Actually, the old-fashioned way would be to use modems. Or to forget about the internet and send snail mail instead.
