I have Firefox 11.0 installed, as well as Google Chrome 17.0.963.65, Opera, and of course, Epiphany on my Debian testing machine. I use cups for printing over the network to my hp printer. Chrome, Opera, Epiphany all recognize all the installed printers on my network, but Firefox does not see any of them. I don't even have the print to file option that most posts on the subject talk about. When I look in firefox's about:config at all the print* settings, the printer is there, but it does not show up in the print dialog and I cannot print from firefox.
Anyone else have this problem, and know how to solve it?
Thanks,

A) Have you logged into Cups to see if there is an error?
Yes, I have looked at the cups error logs as well as the admin portal. There are no errors from firefox, since it never sees any of the printers. All other applications (browsers, libreoffice, etc.) print without errors.
B) What does system-config-printer say? http://cyberelk.net/tim/software/system-config-printer/
Is it not postscript? See D - below related to firefox and postscript
Just curious - why would I use system-config-printer when I have the cups web interface? According to the system-config-printer info on debian.org - "In terms of features, it (i.e. system-config-printer) aims to be as complete as the CUPS web administration tool, while being integrated to the desktop."
C) If this is a "permissions issue", you might have to add the Firefox invoking user to the group file:
sudo usermod -a -G lpadmin tomfirefox is running under user mark, and I am in the lpadmin group
D) Are you using a postscript printer? Do you have kprinter installed?
I use gnome, not kde, so no kprinter. gtklp runs and finds all the printers.
Also, why would the type of printer make a difference? If cups can print to that printer, why would firefox care, unless firefox doesn't use cups?
Firefox:
1. 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. This will be done automatically the first time you print. Open any web page and go to:
File --> Print --> choose PostScript/default (it should be the default if you haven't installed any printers yet) --> click "Print"
The problem is that there are no printers int he File --> Print dialog, so nothing to print to.
Once you have done this and it prints, it'll add the PostScript entry you need to edit.
2. In the URL bar, type
about:config to open the config page.
3. In the "Filter" bar, type
print.printer_PostScript/default.print_command
This should filter everything out but that line.
4. Right-click on the line, click on "Modify", and change the entry to say
kprinter then click OK. This will make Firefox print to kprinter any time you select the "PostScript/default" printer.
5. Right-click anywhere in the white space, then click on "New --> Boolean" to add a new Boolean entry. Type
print.always_print_silent
and set its value to "true". This will force Firefox to print to the default printer without prompting you. If "PostScript/default" is the only printer you have and there are no local / network printers, it works great and you can stop here. 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.
6. Once again, right-click and choose "New --> Boolean". Type
print.postscript.cups.enabled
and set its value to "false". That will disable CUPS printing in Firefox, and it will default to the "PostScript/default" printer. 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. There you can choose all your printers, including PDF, PostScript, and any CUPS installed printers :) .
Did you verify the GTK?
Did you check for the gtkrc file?
You didn't give us your exact distro (there are many debian testing versions) so I could not be sure this was not the Firefox gtk bug:
E. If you have an older version of debian (known gtk bug issues) you might try (verify) this:
1. From the terminal change into the gtk-2.0 directory...
cd /etc/gtk-2.0 [if you have a different version,check for the gtkrc file as in 2.]
2. Use sudo and a text editor (my editor of choice is "vi") to create the gtkrc file in the /etc/gtk-2.0 directory...
sudo vi gtkrc
3. Add the following to your newly-created gtkrc file...
gtk-print-backends="lpr,file"
4. Exit the text editor and save your newly-created gtkrc file.
5. Re-start your computer to incorporate the changes. [Not sure why they suggest this step, but it's in all the posts...]
6. Re-open firefox and you should be able to print to "lpr" from it!
Set the default printer:
lpoptions -d printer-nameThe ‘d’ option sets the default printer.
If your shell is bash (which is the most common), you’d use the syntax in your ~/.bashrc file:
export PRINTER=printer-name
I can print from the command line with lpr with no problem. If I go to about:config in firefox, my printer is there with all its different options. But the line print.printer_list is empty. The print.print_command has lpr ${MOZ_PRINTER_NAME:+-P"$MOZ_PRINTER_NAME"}, so I know it is trying to use lpr (same as the print.postscrip.print_command). But lpr works from the command line.
It seems to be that firefox is not finding the list of printers from wherever it is supposed to find them, and so it cannot print.
Right....let's reset the printer:
As a first step, reset the selected printer in your Firefox preferences:
- Type about:config in the Location Bar and press Enter. A list of preferences will appear.
- Find the preference print.print_printer (Note: this preference is missing in Firefox profiles where you've never used the printer.)
- Right-click (context-click) that preference and select Reset. (Some users may need to reset all the print.printer preferences for a particular printer, if resetting this one master preference doesn't solve the problem.)
- Restart Firefox and see if the problem is resolved.
Note: If you get the warning dialog, "Printing failed when starting the document" and if the print.print_printer preference has no printer shown, either you don't have a printer selected, or Firefox doesn't know it is installed on your system.
Follow this instruction to reset by double clicking on print.print_printer and setting your default: http://www.linuxquestions.org/questions/linux-newbie-8/firefox-not-seeing-cups-printers-869422/
[edit]Does not print to paper at all:
If you are having a problem with Firefox not printing to paper at all, and you don't receive a warning dialog:
- Press {Ctrl + P} on the keyboard and make sure that you don't have Print to file selected under Printer > Comment:
- Make sure that your correct printer is selected at Printer > Name:.

Respond with logs and test output with exact versions please?
What is:
# uname -a
Do you have a 64bit distro?
If so, Firefox cannot use the 64bit GTK (another bug); just install the 32 bit.
Exact versions of what? In my original post I had:
"Firefox 11.0 installed, as well as Google Chrome 17.0.963.65, Opera, and of course, Epiphany on my Debian testing"
Missing the uname -a kernel version, (relevant to known bugs, libraries and fixes).
But just manually adding or resetting your Firefox printer (if everything else is normal) (after upgrade) should fix it.
