Brother MFC-9320CW Printing For Arch Linux pt2

Despite writing my prior post only after months of satisfactory and dimensionally correct printing, I have nonetheless jinxed myself by writing it, and shortly after my printer suddenly started eating the margins of my content again.

After re-installing any packages I could see as possibly relevant (cups, AUR brother drivers, SANE scanning, etc.), following my own steps from the previous blog post, and editing PPD files manually, I was still unable to get output consistent across all applications.

Here’s the magic trick

Run: brprintconf_mfc9320cw

You’ll see an output like this:

function list : /opt/brother/Printers/mfc9320cw/inf/brmfc9320cwfunc
resource file : /opt/brother/Printers/mfc9320cw/inf/brmfc9320cwrc

When I looked inside of the file /opt/brother/Printers/mfc9320cw/inf/brmfc9320cwrc I saw:

[MFC9320CW]
MediaType=Plain
PageSize=A4
InputSlot=AutoSelect
BRResolution=Normal

Note the unwelcome PageSize=A4. I am a hamburger american who already set my printer default dimensions in the CUPS gui to letter sized, so this looks like our culprit.

Run this command:

sudo brprintconf_mfc9320cw -pt Letter

Now the inside of file /opt/brother/Printers/mfc9320cw/inf/brmfc9320cwrc shows:

[MFC9320CW]
MediaType=Plain
PageSize=Letter
InputSlot=AutoSelect
BRResolution=Normal

And now all of a sudden chrome, firefox, zathura, etc’s print options all output with proper margins. For some reason I can’t get printing in black and white to work via the system dialog in a browser, the output remains in color. But I’ve driven myself insane enough for now. Good luck to everyone printing in the new year!
