What if my printer can't do postscript?
Do you have access to an HP plotter or printer? You can get your
graphics output into a hpgl file.
Or you can print to DCRT's IBM/370 printer,
which can handle postscript. Then walk over to Bldg 12 to
pick up your output.
Or you can use one of the printers at CIT's
Scientific Computing Resource
Center. Call them at 4-DCRT or visit their web page for details.
My printer prints black-and-white but I need color output.
If you need color printouts on an occasional or irregular basis,

Scientific Computing Resource
Center. They have Macs, PC's, scanners, black-and-white and
color printers available free to NIH personnel. Walk-in use is
provided, but appointments are recommended. See their web page
for details, or call them at (301) 594-DCRT.

If you have your networked Laserwriter registered on helix (see
Can I print from helix to an AppleTalk printer?
, then you can get GCG to print directly to your printer. If
the PRINTER environment variable is not set, type
| lpr -Pprintername
in response to the question. This tells
GCG to pipe the output to the Unix lpr command, and it should
then go directly to your printer.
You can set the PRINTER environment variable by typing
