Description

I got myself a new Epson 9-pin LX-350 today which claims it supports up to 240x144dpi, however by default found that I couldn't get CUPS to print above 120x72dpi. After some tinkering I found that if I manually added

*Resolution 240x72dpi/240x72 dpi: "%% FoomaticRIPOptionSetting: Resolution=240x72dpi"
*FoomaticRIPOptionSetting Resolution=240x72dpi: " -r240x72"

To my PPD and tested it I was able to get the printout in much higher resolution. It sort of looks this change would go in ibmpro-Resolution.xml but I'm unsure if this would break anything else as I'm totally new to this
