Policy
The Department of Computer Science is one of the few departments on campus to provide their students with free printing resources. Use of the Department's printers is monitored on a daily basis. Excessive and unwarranted printing will result in a warning email and possible restriction of future printing privileges.
Department printers are to be used for the sole purpose of completing course related assignments. Work on private correspondence, coursework for non-CSc classes, or flyers is strictly prohibited! Students found to be printing unauthorized work may have their printing privileges suspended. Depending on the severity of the abuse, the student could lose access to the labs or have their account suspended.
Devices and Locations
Printing within the Department is highly decentralized. Most offices and
labs are equipped with their own printing devices. Although it may be possible
for an individual to spool to any number of printers on our network, only the
following printers are designated for public use: lw0, lw7, lw11, lw12,
lw13, lw14, lw22, lw23, lw26, and lw27.
Queue | Location | Type |
---|---|---|
clj1 lw0 lw7 lw11 lw12 lw13 lw14 lw22 lw23 lw27 |
GS713 GS713 GS930 GS710 GS749 GS228 GS718 GS725 GS228 GS930 |
HP CP4025 HP P4014DN HP P4014DN HP 4050N HP 4050N HP P4014DN Brother HL-5250DN HP 2200D HP P4014DN HP P4014DN |
Some offices have individual printers connected directly to faculty and staff workstations. Support for these printers (as well as other non-ethernetted printers) is limited.
What are the default printers in labs under Ubuntu Linux?
There are two printers in each of the student labs, lw13 & lw23 in
GS228, and lw7 & lw27 in GS930. In GS930, the default printer
is lw27. In GS228, the default printer is lw23.
To change the default printer,
go to
System > Administration > Printing
The system wide default printer on that machine is noted with a check mark. To
change your personal default printer, right click on the icon for the
printer you want to make default, and click "Set as default" (the
fourth choice in the second section from the top). A menu asking
'Do you want to set this as the system wide default printer?' will
come up. Click on 'Set as my personal default printer'. Click OK.
That printer will then be noted with a star.
Hung printers
On the Linux systems:
Most public access printers driven by the system printer.cs.arizona.edu
(ibis).
These printers are resettable via a web interface.

Paper Saving suggestions:
Paper and toner are our largest costs with regard to printing. Since most
printing constitutes rough draft rather than finished product, a
little thought and consideration will go a long way towards reducing our
overall printing expenses.
Duplex printing:
Persons with newer printers (lw0, lw7, lw13, lw23, lw27) can use the
double sided print option by simply directing their print jobs to the
duplex (e.g. lw#d) print queue. If the double sided job
results in an upside-down reverse page then this can be corrected by using the
duplex-tumble(e.g. lw#dt) print queue.
lpr -Plw0d file
enscript -2r -dlw0dt
file
Two-up printing:
Other savings come from printing (ASCII files, not PostScript) two or more
pages per side of paper. For example, on Unix systems the command:
enscript -2r -Plw0 file
or
enscript -2r -dlw0 file (on Solaris systems)
will print two pages of output per one sheet of paper (in landscape
mode).
enscript -2r -Plw0 -fCourier8 file
will print two pages of output per sheet of paper, with slightly larger
type.
For listings of programs or other text files, what matters most is clarity; the
output need not mimic what you would get from a lineprinter. Use two columns of
8-point Helvetica in portrait orientation. When that's too tiny, use two
columns of 9-point Helvetica in landscape orientation. If you only need
something for occasional reference, use 7 point portrait. Here is a family of
aliases you might find useful:
set hv=Helvetica
# normal (portrait orientation) listings
alias lw6 "enscript -2 -T7 -f$6 -F$-Bold10"
alias lw7 "enscript -2 -T7 -f$7 -F$-Bold10"
alias lw8 "enscript -2 -T6 -f$8 -F$-Bold10"
alias lw9 "enscript -T7 -f$9 -F$-Bold9"
alias lw10 "enscript -T7 -f$10 -F$-Bold10"
# rotated (landscape mode) listings
alias lw6r "enscript -rv3 -T7 -f$6 -F$-Bold10"
alias lw7r "enscript -rv3 -T5 -f$7 -F$-Bold10"
alias lw8r "enscript -rv2 -T7 -f$8 -F$-Bold10"
alias lw9r "enscript -rv2 -T7 -f$9 -F$-Bold9"
alias lw10r "enscript -rv2 -T5 -f$10 -F$-Bold10"
The aliases for the modes mentioned above are lw8, lw9r, and lw7.
If layout matters, as when previewing or printing a PostScript file,
there is "psnup".
Note also that "pslpr" can extract a range of pages from within a
PostScript document if you don't need the whole thing.
Color Printing:
Color printing is relatively expensive and therefore most color devices are
restricted to faculty and staff use.
Students may print color output on the HP Color LaserJet CP4025 (clj1)
printer located in GS713, if sponsored by a faculty member.
