I haven't seen a recent (less than 10 years old) discussion on Postscript vs. HPGL2 Plotting for large format (24x36) plotting, so I thought I would see if anything has changed.

We are needing a new plotter as our HP DesignJet T1100 is now throwing some alarming maintenance error codes. Requiring Postscript removes quite a few models from our selection. We do a lot of plotting from PDF's and I am wondering if the Postscript is still a necessity?
