I cannot print from Firefox, keep getting "an unknown error occurred while printing."

Whenever I attempt to print something from Firefox (email, receipt, and so on), printing fails and I get the message "an unknown error occurred while printing." Printing from Internet Explorer works without any problem.

I came across the same problem today, also using a 2600N. Window updated the drivers through a Windows update yesterday, so I suspect that's what caused the problem since it was working fine before.
I tried the reset in about:config and that didn't do jack, but I was able to solve it by removing the printer with device manager and then disconnecting it from my PC, plugging it back in, and letting Windows reconfigure it automatically. It works now.
Good luck

  • Unable to print anything under the Firefox browser. I get "An unknown error occurred while printing" each time I try. What Can I do?

    I can, however, print when using Internet Explorer. I uninstalled Firefox and reinstalled it to see if that would clear up the problem.....it didn't. Not sure what to do now.

    With the latest updates FF 19 BETA and Acrobat X. The new one with the black PDF screen), I'm having difficulty too printing to Adobe PDF. System Win 7 x 64.
    Printing to physical printers not an issue.
    No errors, but (Not Responding either in FF or Acrobat.) Printing to the PDF printer directly sometimes works. Using the work-around fast enough, it seems to always work.
    I found a work-around:
    Goto Print Preview
    Select Print
    Type in your file name
    IMMEDIATELY press OK and Minimize Firefox.
    All of the progress boxes/windows are getting confused otherwise. With FF opened as a normal page, there are too many different progress boxes.
    Acrobat has one, the windows print driver has one, FF seems to have one and they all can't be on top.
    They will if FF is minimized.
    Incidentally if FF is killed, the "Creating Adobe PDF" shows its face from being hidden.
    I did reset Firefox.
    This is seriously messed up now. It used to work fine until the last round of updates from M$, Adobe and FF.

  • I cannot print, get error 'An unknown error occurred while printing."

    I can see that hundreds of other people also have this problem and I can't understand why Mozilla don't fix it.
    When I go to print an email or a receipt, whether by printer or by PDF, I *sometimes* get the error, 'An unknown error occurred while printing.'
    It is very frustrating as the problem is intermittent. Sometimes it works, sometimes it doesn't... even with the same page being printed. Incidentally, that page can be printed in both Chrome and Internet Explorer without a problem.
    I have tried other "solutions" in similar, now closed, threads. However, 'reset' is not working for me. Closing Firefox and reopening doesn't work either. I have the latest version of Firefox: 14.0.1 and have Windows x64. There is enough available space in the cache...
    I'm just at my wits end with this.

  • An unknown error occured while printing (from Firefox)

    When I try to print from web page I get a dialogue box "An unknown error occurred while printing". The printer works on websites when I use Internet Explorer. Also, if I copy the web page and paste it into a WordPerfect document, I can print a copy. This issue just started 2 or 3 weeks ago; I have not encountered this problem prior to this week. Please advise.

    @sklein65
    I thank you for your reply. My problem occurred when trying to print to the XPS printer, I found, that, if I disabled the UAC, the problem went away. You may want to give this a try. You can access you UAC by entering 'UAC' in the Window's Search Box. I had an additional problem with my 'Pinned' websites becoming unusable, I traced this down to Firefox version 24 (beta channel). I reverted back to v23.0 and I never had the problem, again. Note, that, all versions of v23.0 worked, the problem occurred when v24 was installed. I disabled all auto updating in Firefox.

  • FF 5.0.1 on OS X 10.6.8: An unknown error occurred while printing.

    Two iMacs. Both new. Both running 10.6.8. Both have same software installed.Both have same printers installed. An HP laserjet and a Xerox Phaser 3635MFC.
    FF will not print to Xerox on one it does on the other. Erased hard drive and reinstalled OS X on problem Mac. Same problem. Uninstalled and reinstalled printers. Performed the about:config printer preference reset on all printer preferences.
    After clicking Print on print dialog box, it closes and then drop down from FF title bar displays: Printer Error An Unknown error occurred while printing.
    Here are relevant log entries from Console:

    You are seeing the message because the new AirPort Extreme has some specific System Requirements:
    http://www.apple.com/airport-extreme/specs/
    Setup and Administration
    iPhone, iPad, or iPod touch with iOS 5 or later and AirPort Utility 1.3
    Mac with OS X Lion v10.7.5 or later and AirPort Utility 6.3
    AirPort Utility 5.6.1 in Snow Leopard may or may not work correctly with the new Extreme for all functions. As long as things are working OK for now, you can probably leave them "as is" and wait for another Mavericks update to fix some issues before you "upgrade".
    If you have an iPhone or iPad, you could use that to administer any settings changes on the new Extreme.

  • An Unknown error occurred while printing

    Product Name and Number:  3052A -=All-in-One Printer J611g 
    Windows Vista 32-bit
    An Unknown error occurred while printing
    No changes made to the system. 2 other HP printers hooked up to computer just fine, no issues, but the printers were not working due to age, etc.
    I just bought this printer last night, and cannot believe the issues I am having trying to hook it up, and getting it running. I have been doing everything suggested to me, and things still keep happening that I cannot print yet!!
    "An Unknown error occurred while printing" is the message I am getting when trying to print an invoice. I have uninstalled the printer, and reinstalled it, and at that time it showed everything to be working.....CD downloaded good, and the USB cable was connected correctly. I have run a HP Diagnostic, and all of it showed green check marks by everything. I have done HP updates, have done window updates, and I have NEVER had this kind of an issue with hooking up a HP Printer. Is it because it is for wireless also, and I do not have that hooked up at this time? Do I need to return/exchange this one for another HP Printer? I am really confused, need to get these invoices printed for customers, and what am I suppose to do? I really don't have time to sit around too long, and wait for solutions to this issue.

  • 1018"an unknown error occurred while printing"

    HP1018
    Windows 7 64-bit
    Print test works ok, prints from OpenOffice and some other applications.
    However, from Adobe Reader X 10.1.6 nothing happens after clicking on the print dialog button. I have also tried "Print as Image," and there is no response from that either.
    Firefox 18.02 returned "Printer Error: An unknown error occurred while printing."
    I have also updated the driver to "lj1018_1020_1022-HB-pnp-win64-en.exe" which installed identifying itself as a "1020 Series".
    That install appeared to install correctly, and the above applications which _could_ print before can still print ok, but the same problem occurs with Adobe Reader X 10.1.6, with not repsonse after successfully using print dialog, both regular and "print as image", and same error, "Printer Error: An unknown error occurred while printing," is returned from Firefox 19.0

    It sounds like there's a compatibility problem.  You might try a different reader.  Here's a link to a PDF reader that is similar to Adobe.  Click Here  You might try another browser such as Chrome.

  • Can't print from Firefox - "Printer Error- An unknown error occured while printing"

    I am unable to print anything from Firefox! I am using Firefox 19.0.2.
    I performed a "Reset To Default State" for Firefox yesterday to fix some performance issues. Those issues are resolved, but now I can't print!
    I am able to print to 'Microsoft XPS Document Writer' and save as an .xps file. But I am unable to actually print to my HP LaserJet printer.
    Here are the steps I have taken trying to resolve the printing issue-
    I opened the prefs.js file in WordPad and removed all entries beginning with 'print'.
    (When it did not resolve the issue, I restored the prefs.js file with a backup)
    I downloaded and installed the latest driver for my printer from HP.
    Still unable to print from Firefox after taking those steps. Note that I am able to print from any program other than Firefox.
    What steps can I take to fix this issue?

  • "An Unknown Error Occured While Printing" in Firefox 15 for Mac

    This is the newest version of Firefox. I've tried solutions from previous threads, and nothing seems to be working. It looks to be a system issue as it happens in all user accounts. When I went to about:config and searched for print.print_printer that preference does not come up. Tried deleting Firefox entirely (including application support and preferences) and reinstalled. Still doing the same thing. Can print from other browsers fine.

  • I keep getting an unknown error occurred (-50) when trying to download

    I just bought: episode 1 of season 1 of Lost Girl (Standard Definition).  It offered to start playing it.  When it did it, almost immediately, showed the above error.  Whenever I try to re-download the file, I get the same error.  I have run the network connectivity test and it says everything is fine.

    Fingers crossed. But if you still run into trouble, perhaps try the "Error -50," "-5000," "8003," "8008," or "-42023" section in the Specific Conditions and Alert Messages: (Mac OS X / Windows) section of the following document:

    Hi Shelly,
    Are you trying to log in to ExportPDF from Reader? If so, please make sure that you have the most current version by choosing Help > Check for Updates in Reader. You should be using version 11.0.07 (Mac OS) or 11.0.08 (Windows)--earlier versions caused this sign-in error that you're seeing.
