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 shall result in an electronic warning message 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! Users caught doing such unauthorized work will have their printing authority suspended, may be asked to surrender their electronic lab access card, and may have their accounts on Department machines closed.
Department printers are not to be used to produce copies of the online man pages except in the instance of a few often used commands. Attempts to print off large numbers of man pages or other documentation will result in a restriction of future printing privileges and possible termination of account access.
For laser printers the definition of excessive printing is currently set at about 400 pages per month.
If a job is inadvertently submitted to the printer then it can be stopped by
the user with the lprm and/or cancel command (see the man
pages for more information).
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, lw1, lw7, lw11, lw12,
lw13, lw14, lw22, lw23, lw26, and lw27.
| Unix Queue |
Location | Type | dpi | Mem | Post Script Level (Emulation) |
|---|---|---|---|---|---|

clj1 lw0 lw22 lw23 lw27 |

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.
How to add a printer under Windows.
When Windows machines are built, drivers are installed for printers based on
the original location of the machine and the person to whom it is assigned. As
machines get moved from one location to another and/or are assigned to new
users, this may become outdated. We have attempted to install and share all
public printers on the server rockwell, and you can access them from
there.
To add a printer to your desktop machine, go to
Start > Printers and Faxes
Double click on Add Printer. Select A network printer, or a printer
attached to another computer; click Next. Choose Find a printer
in the directory; click Next. Click Find Now on the Find
Printers window.
Highlight the printer you want to add and click OK. Choose to make
this your default printer, if you wish; click Next, then
Finish.
If there is a printer you wish to add, but you cannot find it through this
method, send email to lab.
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.
See: www.cs.arizona.edu/computing/services
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, lw1, 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 4550 (clj1)
printer located in GS732, if sponsored by a faculty member.
Common mistakes in color and black & white printing:
1) Failure to understand the operation of printer and applicable software so
that limitations are discovered before publication deadlines must be
met. The Lab staff are by no means guru's in the area of color printing. The
number of systems involved means no single staff member can help in all
situations.
2) Failure to load the right supplies (paper, toner, etc.) in the right
printer. Caution, this can destroy the printer! Especially the pulling of jammed paper from rollers, which can break the cogs off of the gears. Operation of the printers
should only occur up to your level of understanding and training.
3) Failure to notify the Lab staff of large jobs, whether impending or just
finished. Printer supplies have limited lifespans and are expensive. We
therefore stock only a limited quantity of materials. If you use the printer
for a large run, there is no assurance that we will notice supplies have become
dangerously low. Most supplies come from out of town and take a week to two
weeks to arrive--if we rush the order!
