You may print files by typing
your_machine> lpr filename
You must tell UNIX which printer to send the job to, either by setting an environment variable, or by inserting the -P flag. Thus, to have the file myprint.ps print at the printer on the third floor, type
your_machine> lpr -Phpr3 myprint.ps
There are several printers in the department to which you may send your output, as described in the table below.
Printer Name Description Location
hpr0 HP Laserjet IVsi1 Terminal room (3)
hpcolor0 HP Deskjet 1200C Terminal room (3)
lp4 HP Laserjet IVsi Newton Lab (101W)
hpr1 HP Laserjet III 1st floor printer
hpr2 HP Laserjet III 2nd floor printer
hpr3 HP Laserjet III 3rd floor printer
To check on the status of your print job, use the lpq command. for example, to check on the status of jobs on the color printer, type
your_machine> lpq -Phpcolor0
Occasionally, after a job is sent to the printer you will realize that it was a mistake. To delete the job from the queue, first find its job number by using lpq. Next, use lprm to delete it. To delete job number 23 from the color printer queue, type
your_machine> lprm -Phpcolor0 23
If you cannot find the job number using lpq, then it is too late to delete it - it is already coming out of the printer.
