Find print.always_print_silent, right-click on it, and choose "Toggle" to set its value to "False". This will revert Firefox back to its native printing system.Ģ. Find the print.printer_PostScript/default.print_command again, right-click on it, and choose "Modify". If you've already closed about:config, open it up again.ġ. If you ever want to disable these options or revert back to the defaults, simply do the following. You can also customize your Toolbar and add a button for about:config.

How to change default printer in firefox install#
* There's an alternative way to get to about:config in Thunderbird - install the about:config extension. This will also make Thunderbird print to kprinter automatically. Once the about:config window is open, follow steps 3-6 above for Firefox. Click on the "Config Editor." button to open the about:config window.ģ. Go to "Edit -> Preferences", click on "Advanced", then click on the "General" tab.
Just as with Firefox, you first need to print something to PostScript in order for the entry you need to modify to be present.Ģ. The procedure for Thunderbird is exactly like it is for Firefox, but with one difference: there's no URL bar to get to about:config.*ġ. There you can choose all your printers, including PDF, PostScript, and any CUPS installed printers :). And since you've changed the output of that to kprinter, you'll see a "processing" dialog for a split second when you print, after which kprinter will open up. That will disable CUPS printing in Firefox, and it will default to the "PostScript/default" printer. Once again, right-click and choose "New -> Boolean". But if you installed a printer through CUPS, it complicates things as Firefox will want to use that as a default and all your prints will go there without prompting you! So even if you don't have a local printer, it's a good idea to add the following line in case you add one later.Ħ. If "PostScript/default" is the only printer you have and there are no local / network printers, it works great and you can stop here. This will force Firefox to print to the default printer without prompting you. Right-click anywhere in the white space, then click on "New -> Boolean" to add a new Boolean entry. This will make Firefox print to kprinter any time you select the "PostScript/default" printer.ĥ.
Right-click on the line, click on "Modify", and change the entry to say This should filter everything out but that line.Ĥ. Print.printer_PostScript/default.print_command
Once you have done this and it prints, it'll add the PostScript entry you need to edit. Open any web page and go to:įile -> Print -> choose PostScript/default (it should be the default if you haven't installed any printers yet) -> click "Print" This will be done automatically the first time you print. First, if you haven't done so, you need to print to PostScript in order for the needed entry in prefs.js to be populated. So here are the steps I took to get Firefox and Thunderbird to print to kprinter automatically once you click "Print".ġ.
How to change default printer in firefox how to#
Well I know there are a few threads out there on how to integrate Firefox into KDE and how to get Firefox to print to kprinter, but there was nothing that I could find on how to do it automatically and seamlessly (instead of selecting "PostScript/default" manually every time) and not much info on Thunderbird.
