Finally, you are happy with the way your graph looks, so you want to print it out on paper. Many types of hardcopy devices are supported within plotdata, and the one you will be using is the postscript type. PostScript is the name of a ``page description language'' that is understood by many high-quality printers out there, including the ones at Brock. The printers are known to plotdata by their Unix names, and the ones you need to know about are:
Once you know the name of the printer you want to use, get the hardcopy output by following this example:
PLOTDATA: hardcopy
HPL HP Laserjet
PS PostScript
Enter: device code >> ps
Device=PostScript
HARDCOPY COMMANDS
P queue | print
S file | save file
Enter: hardcopy command >> print bj-physics
The only things you have to type here are hardcopy, the command; ps, the printer type; and print bj-physics, the command to print to a given printer, bj-physics in this example. The rest of the text shown above is supplied by plotdata to prompt you.
As you can tell, you could also save the output to a file for printing later or for including it in your lab report, by typing save file.ps at the last prompt.
