Hi, I just installed an Epson Stylus Color 800 printer on Mandrake 6.1 2.2.13-7mdk. I set up the printer with printtool, choosing the Epson Stylus Color (UP) filter and the stc800pl (360 x 360 dpi) color depth. It's working fine, but what is the command for printing at higher resolution? I was reading the ghostscript documentation on the uniprint driver. It says that to select higher resolution, the command is gs @{select}.upp -sOutputFile=/dev/lp{*} file.ps -c -quit If I select a higher resolution upp file, like stc800p.upp for 720 x 720 dpi, I get a screen of errors, like this [kim@weaver kim]$ gs @stc800p.upp -sOutputFile=/dev/lp0 /sigourney/kim/avant.ps -c quit GNU Ghostscript 5.10 (1998-12-17) Copyright (C) 1997 Aladdin Enterprises, Menlo Park, CA.

I can print at higher resolution by going into printtool and changing the color depth, but that's a pain. How can I change print resolution from the command line? Thanks, Hidong
