Re: [Gimp-print-devel] Gutenprint and Epson Pro 7900

[Ronald J. <ro...@vo...>]

I am using the Gutenprint PPD that shows as an option when I add the printer in System Preferences.

I tried editing the "escp2/model/base/pro_ultrachrome_k3v10.xml”, which is supposedly the correct file for the Pro 7900 and I tried rebooting and reconfiguring. 

I also tried the same with the other versions A and B of that same XML file.
