Spooler.exe tries to communicate with shared printer on TCP:47546 port

Hi,
We have:
1. AD
2. Win7 Pro Workstations
3. Symantec Endpoint Protection - allowed only SMB ports (135,137,138,139,445), denied all other communications incl broadcast.
4. WS2 - computer with shared printer
Issue: As I can see in WS1 SEP Logs spooler.exe tries to communicate with WS2 on the TCP:47546 port. SEP blocks those communications and shared printer stays "grayed". The solution I found is to restart spooler. Sometimes it helps
Why does it happen? What should I do to force spooler to comunicate on standard SMB ports?
UPD: Printer shared and as \\WS2\Printer and as \\IP\printer - in both cases the issue persists

Hi,
I am Chetan Savade from Symantec Technical Support Team.
You can either add printer to excluded host.
To add the printer to "Excluded Hosts":
1. Open your Intrusion Prevention Policy.
2. Choose to Settings on the left.
3. Check the box for Enable excluded hosts and then click the
Excluded Hosts... button.
4. Add the IP address of your printer and choose Okay.
Can refer the following article to create remote port exception.

How can I make my macbook to communicate with my printer?

Hi everybody!
I recently bought a printer(Epson PX820 FWD)and I`ve tryed to instal the drivers on the Macbook.All good but when the Macbook tries to communicate with the printer I have a message saying that there is no printer found.
Can somebody help me? I`ve fallowed the instructions precised

It would help to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report if you’re running 10.7 Lion or 10.8 Mountain Lion). When System Profiler comes up check the Model Identifier and post it back here.

Help needed to communicate with networked printer

I have a iMac G5 with Airport card. I am trying to communicate with an HP7660 printer attached to a WinXP machine with a USB cable. I can communicate bidirectionally fine with shared files between the Mac and the PC. I have turned on the file sharing on the printer itself. In the Mac, in System Preferences/Print & Fax, I set up the printer in the Printer Browser window with the following:
Protocol: Line Printer Daemon - LPD
Address: I used the IP address of the PC
Queue: left blank
Name: hp7660 (same as I gave it on the PC)
Location: I used the IP address of the PC
Print Using: Generic Postscript Printer (this was the default since this model was not shown in the printer list.
In the Print & Fax, under Sharing, it shows the hp7660 checked.
In Printer Setup, "Printer model" shows Generic Postscript Printer.
In Printer Setup, "Name & Location" shows correct for both. The Queue is shown as hp7660 and the driver version is 10.4 (the Mac version).
Now, when I open a Word file and click on "File/Print", the "Printer" is hp7660. When I click Print, I get an error message that says
"Network host "IP address" is busy, down or unreachable; will retry in 30 seconds..."
This same thing happens regardless of the Protocol option that I choose: Line Printer Daemon, Internet Printing Protocol, or HP Jet Direct.
During this time, I get no error message on the PC and there is no other work going on at the PC. As I said, I can easily communicate between both machines, except for the printing.
If all of the configuration settings are correct, does anyone have any ideas that I might have overlooked?
Thanks
Herschel

Henry,
Thanks for being so patient with my problem.
When I follow the efelix directions for setting up the PC, it says that when you press the "Add" button on the Mac, a drop down menu will appear so that one can choose "Window Printing". This is not what happens for me. When I push the "Add" button, a "Printer Browser" window opens.
This Printer Browser window (in the first box) gives me only 3 options: the LPD, IPP and Socket options. After manually entering the Address (IP address of PC), Name (same as shown on the PC), and Location (IP address of PC), the default in "Print Using" shows up as "Generic Postscript Printer". I then click on the "Print Using" using option to choose the HP Photosmart 7660 printer from the list rather than the Generic Postscript Printer.
Now, when I click on "Add", the "Windows Printing/Workgroup" comes up in a Printer Browser window. It has only one item under the "Name" column which is my name and under the "Comment" column it had the Mac ID listed. I then choose "Network Neighborhood" as suggested in the efelix website. What appears now is a single choice called "WORKGROUP" under both the "Name" and "Comment" columns. I should have had 2 choices (as efelix shows), one being "WORKGROUP" and the other being a workgroup that contains my remote PC.
This procedure, according the efelix procedure broke down at the very beginning when he suggests clicking on Add immediatly after setting up the PC. I did not get the drop down window he shows in order to choose "Windows Printing". Rather, this choice did not appear until I went through the configuration procedure of manually choosing the "HP Photosmart 760 Foomatic/hpijs" from the printer list. I don't know whether this may be due to a difference in Panther or Tiger (which I have), but the way I did it does not allow me to make the connection.
So, in summary, it requires that I take a different path to get to the same conditions that efelix shows. Obviously, it is not getting the results needed. I sometimes wonder whether deleting the "hpijs" and 'ghostscript" and just using the HP upgrade might work? What do you think? Or is there some other way to get the "Add" window to give me the drop down window?
I know this may be confusing, but I am trying to give you the step by step procedure that is happening.
Thanks
Herschel

Communication Failure: The computer is no longer able to communicate with your printer.

Hello, I have a HP Officejet J6480 All-in-One printer. When I try to print, I receive this error message:
"Communication Failure: The computer is no longer able to communicate with your printer. Turn the printer off, check your printer connections and check for printer errors, and turn the printer back on."
I am using a Mac PowerBook G4, OS v10.5.7. I have tried the following:
-- rebooted my Mac
-- turned printer off/on
-- rebooted wireless router
-- tried to print using USB cable.
I continue to receive the same error message. Helllllllllllllllp!!!!
A couple of other things I need to mention: I bought this printer in June and have been able to print just fine since purchasing
this printer. As recently as Friday, July 3, I was able to print and printed 6 or 7 pages then. This is CRAZY!!!!
Thanks.

Macbook on longer connects with shared printer

Whenever I try to print from my Macbook using a shared printer I see this error message :
can't open `/private/var/spool/cups/tmp/50d23352019a8'.
The shared printer is attached to a PowerMac G5. The G5 printer sharing is on, and the correct printer is selected.
This problem just recently started.
In the Macbook's Systems Prefs Print&Fax pane it shows the G5 shared printer by name and its location.
I believe something is wrong with my Sharing Pane in my Macbook's System Prefs.
This pane shows the printer's name and the G5's location, the Printer sharing box is checked and the Printer Sharing green light button is on
However the two rectangular boxes marked Printer and Users are both empty, and the + - signs are both grayed out.
They used to contain the printers name in the Printer box and everybody in the users box.
Any suggestions as to how to fix this? Do I need to make a change in CUPS?
Thanks,
Walter

Try Add a Printer.
In System Preferences / Print and Fax, the padlock has to be unlocked to get access to + and -.
Remove the old printer name etc. (the - sign), then click on the + sign to add the same one back again.

A network error occurred while trying to communicate with the server.

Hello All,
I am getting some new error messages when opening the server app on my Mac Mini server running OS X 10.8.2 and Server 2.2.1. First I get a message that says "A network error occurred while trying to communicate with the server." and then after trying to open some of the service panes, I get additional errors that say "Multiple errors occurred on the server while processing commands." The services don't load and I just see "Error Reading Settings" in the server app.
I started to get these errors when I added a new website to the server. All the services are working fine but I cannot access them in the server app.
In console I'm seeing these errors when I try to access various services:
2/24/13 8:02:12.692 PM Server[956]: Error: The server '10.0.1.150' reported an error while processing a command of type: 'readSettings' in plug-in: 'servermgr_dns'.

I have already restarted the server and used terminal to stop and start postgres. Any more thoughts on how to repair this?

Just as I had suspected, the whole GUI crashed because of certificate problems. After two and a half hours with enterprise support, it turns out the com.apple.servermgrd certificate in the server keychain had become corrupt.
We determined this by typing https://127.0.0.1:311 into Safari and we could see all the server modules and interact with them through the web interface. All the services were working properly as well so we knew that it was just the Server.app GUI that simply couldn't read settings that was causing the problem.
So, first we closed the server app. Went into /var/servermgrd and deleted all the files from this folder. Then, in Keychain, deleted the com.apple.servermgrd certificate. Did a search for com.apple.servermgrd in Keychain and deleted everything else that came up for it.
Then restarted the server. Now the server app was able to properly connect to the services in the background and read them properly. This was the jist of the troubleshooting that solved the problem. It also seems like DNS is causing problems because that is the only service that will not read right but is functioning properly in the background.
I will post an update once Apple figures out what is wrong with DNS. Hope this helps anybody else having these problems.

An error occurred while trying to communicate with the web browser.

I have opened a PDF in the Acrobat reader V 8.2.4. It has live links.
Only the FF browser is open.
When I click a link in the PDF, I successfully get the message 'The document is trying to connect to...' which I allow and then successfully hyperlink to the web page displayed in FF.
When I click an image in the PDF, which has a url attached to it, I get the message 'An error occurred while trying to communicate with the web browser.'
[Sorry to say in IE7 when I click the image, I hyperlink to the web page like I do when I click the link.]
Question is: What setting or other step do I need to take with FF so when I click the image in the PDF I link to a web page like I do when I click the link in the PDF?
Thank you!

6500 E710 unable to communicate with the printer

I have an HP Officejet 6500A Plus E710n-z. It has in the past but it no longer connects (through wireless) to my computer (Apple OSX 10.8.4). It has become intermittent over the last month, and then did not respond at all. I had a growing list of items to print.
I have followed each of the steps on - http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02205477&cc=au&dlc=en&lang=en&lc=en&product=408... .
Wifi to each is not a problem.
The printer has been disconnected (deleted) as the computer printer. I have been able to add back in the 'scanner' part of the printer, but cannot add in the printer - it has the message 'unable to communicate with the printer'.
What do I do next?
This question was solved.
View Solution.

I would recommend that you do a hard reset on the printer. To do that, use the following steps.
1. Press the Power button to turn on the product.
2. With the product turned on, disconnect the power cord from the rear of the product.
3. Unplug the power cord from the wall outlet.
4. Wait at least 15 seconds.
5. Plug the power cord back into the wall outlet.
6. Reconnect the power cord to the rear of the product.
7. If the product does not turn on by itself, press the power button to turn it on.
Try that and let me know if it helps!
Best of luck,
Kyle

Trying to Communicate with WinAmp

Hi,
I am trying to communicate with WinAmp (MP3 player) through the sendmessage function in User32.dll
So far I can send commands like play, stop, forward, play next etc. but sending a filename to play gives no result.
This is the structure of the command:
#define IPC_ENQUEUEFILE 100
/* This is sent as a WM_COPYDATA with IPC_PLAYFILE as the dwData member and the string
** of the file / playlist to be enqueued into the playlist editor as the lpData member.
** This will just enqueue the file or files since you can use this to enqueue a playlist.
** It will not clear the current playlist or change the playback state.
** COPYDATASTRUCT cds = {0};
**   cds.dwData = IPC_ENQUEUEFILE;
**   cds.lpData = (void*)"c:\\test\\folder\\test.mp3";
**   cds.cbData = lstrlen((char*)cds.lpData)+1; // include space for null char
**   SendMessage(hwnd_winamp,WM_COPYDATA,0,(LPARAM)&cds);
WM_COPYDATA = 0x4A
In the VI you can see what I did. Before running the VI WinAmp must be already started. The led "windowfound" should be on.
I tried several things but no luck so far.
Can someone help me out with this problem ?

Thank you for your priory information. I need to communicate with a C++ program using WM_COPYDATA. Since I need to send as well as receive data, I tried to write codes that send and receive WM_COPYDATA in LabVIEW. I think I succeeded to send WM_COPYDATA by following your example. However, I could not succeed in retrieving received COPYSTURCTURE data. Since I receive pointer I think I need to retrieve the data from the memory. I tried to use Moveblock, however, I failed. I am attaching my example codes. Please take a look and give me comments.

VISA unable to communicate with or see RS232 serial com port

I have a Dell Optiplex GX260 which has recently had Windows XP (Service Pack 2) re-installed on it. National Instruments VISA is unable to communicate with the single RS232 serial com port on the computer. Neither the "VISA Resource Name" control in LabVIEW 8.5 nor the "Measurement and Automation Explorer" can see the serial port. Refreshing the list does not help. "HyperTerminal"is able to both see and communicate with instruments connected to the serial port. In Windows "Device Manager, the serialport appear in the list of hardware without any warnings.
Can anyone please help with suggestions as to how I may be able to get VISA in LabVIEW to 8.5 to see and communicate with the serial port?

First, there is a plethora of messages on this forum and a plethora of information in the NI KnowledgeBase. If someone doesn't make the simple effort to take 5 minutes to perform a search what does that say? The issue being raised has come up, literally, dozens of times. Do you like answering the same question over and over and over and over and over again?
Second, my feelings are not unique. You will find that the irritation of people not bothering to do a simple search is shared by most of the regulars here. Why do you think search engines are available? Just so that ads can be sold?
Third, posting the SAME question in multiple threads is self-defeating. People who try to answer don't know what's already been suggested, and end up wasting their time as well as the poster's time in providing the SAME answer and/or suggestions that were provided in the other thread.
Fourth, simple forum netiquette. In both threads the poster essentially hijacked someone else's thread. This is frowned upon in just about every forum that I've ever seen.

Problem with shared printer after upgrade to Maverick

Hi Guys,
I have one iMac and two windows PC which connect to the same WiFi router.
The iMac has a HP LaserJet CP2025 attached to its USB port and shared with other windows PCs with no problem.
Until I upgrade my iMac to Maverick recently, now those PCs cannot see the shared printer anymore.
Do you have any ideas what configuration is changed in the Maverick which could cause this please?
I have been searching through Apple communities and other tech forums and have tried many solution, but still cannot solve this. (I have also tried setting up LDP, but no luck so far)
PS ... Shared files seems to work fine. I can access (read/write) the shared files/folders from windows with no problem (SMB and AFP enable).
Any ideas, pointers or links would be appreciated.
Cheers,
ChaaPru

Error message when trying to set up shared printer

I can't seem to add my ancient agfa imagesetter to my list of printers. The rip software is running on an old mac running system 9. I've tried typing in the printer's IP address, but that doesn't work either.
So I thought I could work around that by sharing the printer from my G5 which is running system 10.4. So Mountain Lion now sees my agfa in the shared printer list, but when I go to add it, the error message is "Unable to download the software from the server at this time."
My best guess would be an issue with sharing permissions, but I am open for suggestions. I can't add any of the printers from the shared printer list, so it is not my agfa that is the problem with my workaround solution, it is a "sharing" problem with my G5.
Ideally, I'd like to print directly to my old rip, but if I can't, if anyone can help me solve the "sharing" puzzle, I would greatly appreciate it!!

If you are using LELA delete it from your computer. It is not needed. Connect viw your wired computer to 192.168.1.1 username blank password admin (or whatever you made it) and configure your router manually.

Powerbook Printing to a WinXP PC with Shared printer issue

I've recently made the switch for my laptop to a Powerbook G4 and am very very happy with it. There is only one thing that I cannot seem to get working though.
I have a Canon i950 Photo Printer hooked up to my desktop XP machine via USB and have it shared for network use. When I try to print to it over the network with my Powerbook, no matter what I try the text is always comicly small to the point that it is unreadable... picture a full page of text printed into the top corner of the page, scaled down.
When I connect the i950 directly to the powerbook with USB, it prints perfectly and I've got no issues. It appears that it uses a different driver for local printing as opposed to network printing.
Does anyone know of anything I can try to resolve this?

I dont have an airport express, but the thought did
cross my mind to pick one of those up. I'm not
familiar though how an XP machine would connect to
the Airport Express though.
