Affects Firefox versions 4 to 17, while printing to PDF.
For some reason I have never been able to print a borderless (zero margin) page in Firefox on Linux. Even when creating a custom page size and explicitly setting all margins to zero the prints would contain a margin.
This frustrated me for a while untill i discovered this workaround:
- type ‘about:config’ into address bar
- search for ‘margin_’ in the filter area.
- change the “printer_Print_to_File.print_unwriteable_margin_” keys to zero.
I hope this helps others that run into a similar issue.
