Firefox Community Forum

I recently started to have a printing problem in Firefox on Windows 11. My Brother DCP-T720DW works fine with other applications like Word and Notepad, but when I try to print from Firefox, sometimes I get a "Printer not available" message or the print dialog incorrectly shows the printer. For troubleshooting, I uninstalled and then reinstalled the printer driver following the official Brother download page: https://support.brother.com/g/b/downloadtop.aspx?c=us_ot&lang=en&prod=dcpt720dw_all Since that didn't fix the issue, I also downloaded and reinstalled the driver from: https://printerdrivers.com/brother-dcp-t720dw-driver/ Windows detects the printer and is able to print test pages, so it looks like the problem is only with Firefox. Here are the things I have tried: Restarting both Firefox and Windows Uninstalling and reinstalling the printer Resetting Firefox settings Running Firefox in Troubleshoot Mode Making Brother printer the default one

Has anyone else had the same issue in which Firefox refuses to detect a printer that works correctly in other applications? Is there a print setting or preference in Firefox that might cause this? Thanks in advance for any advice.

Hey all, I'm hoping someone can help me. I have found no answers online to date.

I cannot print from the Firefox browser. When I click the print button, my printer spits out a blank page.

I can print from any other browser, Word, Excel, PDF files, anything except for Firefox. This may not be as much of an issue if Firefox wasn't my primary browser, so when I start doing work on it and find I need to print something at the end, it's a problem.

My printer software is up-to-date, I tried resetting the printing preference to default (assuming I did this correctly), and I even uninstalled and re-installed Firefox (which was a disaster). None of this helped.

Is there one of you who may be able to provide me with the help I need?

I appreciate your effort greatly.

'Running ver 137 and now cannot print to my system default printer. Tried the Troubleshoot fix and same result - defaults to PDF. Is there any entry in about:config to ensure system printer is selected. I have checked all system settings and brother printer is the default.
