I'm back...
Got everything working right in GIMP, followed Online Manual.
Now running app PhotoPrint. Set up the same way as GIMP (PPD, Command, etc). Something goes to printer, get a few blinks, but no output. Running Photprint from terminal I can see it puts -oraw in the command line. In the setup it is not there. Don't know where it is coming from, suspect that is the problem.
has anyone sen this? Thanks.
