Unwritable Margin Bottom changing back to default

more options

I'm using an HP LaserJet P2035 to print documents from firefox. The footers are cut off, so I need to edit: print.printer_Hewlett-Packard_HP_LaserJet_P2035.print_unwriteable_margin_bottom However, when I change it from it's default of 17 and print, it changes itself back to 17.

Is Firefox increasing the value or decreasing it?

Firefox may be updating the "unwriteable" preferences based on information derived from its reading of the Windows printer driver data. Could you try setting this alternate preference and see whether it sticks:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button accepting the risk.

(2) In the search box above the list, type or paste edge and pause while the list is filtered

(3) Double-click the print.printer_BrandX.print_edge_bottom preference and enter your desired distance in hundreds of an inch (assuming you use inch measurements). For example:

  • 10 => 1/10 inch
  • 25 => 1/4 inch

In a different tab, use print preview to test that there is now that amount of space between the bottom edge of the paper and the page footer.

Any difference?
