Here is what I use to send HPGL jobs to an HP 1055 plotter. The PJL
commands set the job name (so the jobname appears on the printer's LCD
screen) and switch the printer into HPGL mode. It has been a while but
I seem to remember that I needed to have the switch to HPGL mode even
though the "copy file lpt1" style worked. Perhaps you will need
something similar?

import win32print, os

UEL= "\x1b" "%-12345X"   # control code to get to PJL
p= win32print.OpenPrinter(r"\\server\design10")
filename= "blah.000"
jobname= os.path.splitext(os.path.split(filename)[1])[0]
j= win32print.StartDocPrinter(p, 1, (jobname, None, None))
f= open(filename, "rb")
buffer_size= 100000
t= f.read(buffer_size)
win32print.WritePrinter(p, UEL + "@PJL JOB NAME = \"" + jobname +
"\"\n at PJL ENTER LANGUAGE = HPGL2\n")
while t:
  win32print.WritePrinter(p, t)
  t= f.read(buffer_size)
f.close()
win32print.WritePrinter(p, UEL + "@PJL EOJ \"" + jobname + "\"\n" +
UEL)
win32print.EndDocPrinter(p)
win32print.ClosePrinter(p)
