If you have an old HP plotter, you will find that the Mac OS X drivers available from HP’s support site can not be installed because they are in an old VISE .hqx format installer.

If you go and get a generic PPD for the printer, and stick it gzipped in /Library/Printers/PPDs/Contents/Resources then you will be able to select it as a printer type when you add the printer.

Attached is the one I found and used. It needs more work, I am getting postscript errors at the end of prints which can use a lot of paper. But it is working.

Update: It looks like you can disable postscript error printing with…

defaults write com.apple.print DoPostScriptErrorHandler NO

…and re-enable it with…

defaults delete com.apple.print DoPostScriptErrorHandler

Update2: The defaults thing does not appear to work.

Update3: Using HP JetDirect as the protocol instead of LPR seems to have fixed the PostScript error problem.

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?
