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:
With the exception of bj-physics, the printed output costs $0.10 per page,
which is collected when you pick up your output.
the printer of choice, this is the BubbleJet printer in B203.
Your output is available for pickup whenever B203 is open, which is most
of the time. At the moment, Department of Physics is subsidizing the cost
of course-related printing on this printer; please, do not abuse this
privilege as this will result in an immediate termination of this policy.
this is the central printer
of the University's Computing Services. It is
located in F301 and your output is available for pickup during the
normal working hours.
the same printer! - except when addressed by this name, the multipage
output sent to it gets printed
in duplex mode, i.e. on both sides of the page.
this is the printer in the Physics Office. Prior to printing there,
please obtain secretary's permission so that your print jobs do not interfere
with her work. Again, locked after hours.
as the name suggests, this printer is located in F316, and is only
convenient when you are next door, in F317. Since some
evening classes use those rooms, there
usually is a TA on duty to give you your output.
Once you know the name of the printer you want to use, get the hardcopy
output by following this example:
HPL HP Laserjet
Enter: device code >> ps
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.
