Is there a way to call kprinter instead of the gtk printing dialog to work around this crash?

Comment 2

[Gustavo Homem]

It doesn't crash if

print.always_print_silent is set to true. 

But even with the folowing preferences set:

print.always_print_silent;true 
print.postscript.cups.enabled;false
print.postscript.enabled;true
print.postscript.print_command;kprinter 
print.printer_PostScript/default.print_command;kprinter

Firefox 3 still connects directly to the CUPS server.

I tried removing /usr/bin/lp* and it is clear that "Firefox 3" doesn't use any of them. I could see with netstat that it connects directly to localhost:631.

*QUESTION*

How can one force the postscript module to be used, so that Firefox submits postscript via "lpr" or other custom command?

Thanks you very much

Comment 3

[Gustavo Homem]

Additional info:

- if cups is down and print.always_print_silent==false, firefox 3 shows the Gtk print dialog with only the "print to file" option available (doesn't crash)
- the print.printer_list preference is ignored, the list of printers stays empty regardless of this preference

The following messages appear on the terminal:


** (Gecko:4675): WARNING **: Error result: Too many failed attempts

** (Gecko:4675): WARNING **: Error getting printer list: Too many failed attempts

[Daniel Holbert [:dholbert]]

See bug 422916 comment 28 -- this crash is a bug in the GTK2 library, fixed at some point between 2.10.6-* and 2.10.13-*.

[Gustavo Homem]

Thanks Daniel.

It would important how to bypass gtk and let firefox print postscript via a custom command.

Comment 6

[timeless]

it becomes less important over time. we're unlikely to fix it, but it's a different bug.

do you mean not being able to print via postscript/lpr/custom command is a bug? or has the procedure just changed?

If it is a bug, it is a regression from Firefox 2, where we could do that.
