Tried creating a custom paper size with zero margins and QTR set the margins to their default values. I then tried setting up the page in Print Tool using the Epson Driver which has borderless options available, but that did the same thing.
I opened the PPD file for our Quad9880 printer out of curiosity and it seems like custom paper dimensions could be added in which the margins are set to the very edges of the paper, thus creating system supported borderless printing options.
If I have time this week, I'll see if I can try futzing with that. Seems like it could be FUN.
Cheers!
