IDL generates PS file that prints slow [message #3304]

Dear IDL-programmers,

I am frustrated with IDL because it generates PostScript files that
prints out very slow. Are there anybody having the same experience?

A very simple code to test this problem:
set_plot, 'ps'
x = randomu(s, 20000)
y = randomu(s, 20000)
PLOT, x, y, PSYM=1
device, /close
spawn, 'lpr idl.ps'
This script will generate a PS file of about 200KB, but it will take
more than 30 minutes to print it out in a Sparc Printer. Normally,
the Sparc printer will take only 2 minutes to print out a file of 200 KB.

Can any one tell me what could be the problem? Could it be that IDL
generates low effeciency PostScript files?

Thanks a lot, and Merry Christmas!
