I installed qtr for my P7000 (using the p800 drivers - using the InstallP7000=... command - and it works quite well for making prints.
When I try to make a digital negative on Pictorico, however, I get some pretty nasty pizza wheel marks. I can deal with them with I print through Photoshop (by making tweaks to media thickness and other settings), but I don't know if there is a way to make these sorts of tweaks from within the qtr printer driver. Any suggestions?
