The HP7475 will not work with HPGL/2 it needs HPGL/1 -- period!
I am also looking for a HPGL/1 driver for Win2000.
I have surfed a few forums and the stock answer is usually 'get a new plotter' or use HPGL/2! The problem in my case, and I expect many others, is where a program uses the HP7475 as a virtual plotter to plot to file, for some sort of post processing.
The HPGL/1 code is character based and easy to process.
Most CAD/ graphics programs will directly import HPGL/1 but not HPGL/2. :sad:
The only option I have found (not tried) is to spend $200 :-( on a propriety driver from
