Have you tried AutoDesk's DWG TrueView Software?? Its a viewer/markup program that has a lot of plotter drivers including some for HPGL plotters like the 7475A and one for the Draftmaster 2 HPGL.
Its free and comes in versions for WinXP 32/64 bit and Win7 32/64 bit. I don't work for them, I just use the software for drawing review, but I did notice the plotter setup tab included HP plotters. I believe it handles dwg and dfx files but there may be some font incompatibilites.

Thank you for that link.

A perfect HP 7550A output file at the touch of a mouse button.

Well, I did need to set up a "save to file" location.

Progress with an old machine!

Should work just fine with the OP application.

Best regards

Glad to be of some assistance. What, if I may ask, are you using for a cutter/holder, assuming you are cutting vinyl?? I made up a holder on my mini-lathe for an exacto swivel knife out of delrin that works ok but I am thinking there might be something better. The knife is a tight fit in the delrin and height adjustment is by friction. I also made up a Sharpie finepoint penholder out of delrin that works quite well and allows you to substitute any of the colors they have available if doing artwork on paper, pcbs, etc. I did have to trim the case to allow access to the carousel of the 7475a.

Next mod is to fit a hispeed spindle to allow engraving/milling of pcb directly. Probably won't be able to do tight spacings or tiny pads but basic boards should be possible.....

Just something about these old plotters just clicking and whirring away that a modern inkjet printer just doesn't have.
