Works for me, OS X 10.13.4 on 20180518. Copied gzip directly to /Library/Printers/PPDs/Contents/Resources and renamed to ‘HP DesignJet 755cm.gz’
Selected with JetDirect card & protocol. After print completed (looks good, color from Fusion360 demo sheet size B), there was about a ‘C’ sized drawings worth of blank, followed by text indicating “Error Undefined, OFFENDING COMMAND: Stack”
Thanks, would like to improve it too…tried with Windows drivers and Parallels multiple times. You’ve saved my DesignJet Thanks.
Thanks for posting this. I’ve been searching for this PPD for quite a while. Did you did it out of an Adobe set per chance?
Yep, I ran into the same issue last week. There is an open ticket to track it: https://bugs.launchpad.net/qemu/+bug/1336794
