If a print queue is excessively long, or the printer keeps reaching the
79 error after rebooting, the queue may need to be trimmed. If your
own job is causing problems, please remove it with the command lprm
(or
lprm -Pprintername
). Otherwise, you can
contact the Athena printer administrators with the commands:
athena% zctl sub message printadm \*
athena% zwrite -i printadm
Send a message indicating which printer is stuck and why jobs actually
need to be removed. Frequently, the output of lpq
will claim a printer has "stalled" for several minutes
(especially for large pdfs), when it is simply
in the process of printing that job and nothing is wrong.
athena% add consult
athena% attach-usb
You'll be prompted for the cluster root password. We can't print it
here, but you can find it by typing the command tellme root
.
Once you attach the drive, it's available in the directory
/mnt/usb/
. If you want to access it from the GUI, you can
click on the Computer icon on the desktop, select
Filesystem, mnt, and usb.
When you're done with the drive, type detach-usb
before removing
it.
Writing to optical media is easy on Linux computers (it is much harder to burn CDs from the purple Sun computers). Click on the Computer icon on the desktop, and select Places | CD Creator. You can then drag and drop files from your home directory to the blank window that appears. When you're ready to burn the CD, click File | Write to Disc.
If you have an ISO file you want to burn, you can do so by
right-clicking on it and selecting Write to Disc. (Note that when you're
downloading large files such as ISO files, if there isn't enough room in
your home directory, you can save them to /tmp/
, which is
temporary storage space on the current computer.)
alsamixer
. This will bring up a menu that you can
manipulate with the arrow keys. Bring "Master Mono" — the
built-in speakers — all the way down,
and "Headphones" to the volume you like. If you still don't hear sound
through the headphones, make sure that the other channels such as Master
and PCM are up and unmuted. You can mute and unmute with "m". When
you're done with alsamixer, hit "q".
On Sun machines, you can use the command
sdtaudiocontrol
to send audio to your headphones
instead of the built-in speakers.
The New Media Center in 26-139 is a cluster of Athena-compatible Macintosh workstations that has a color scanner. The NMC also has a laser printer, and computer hookups for various video formats, including DVD, VHS, and MiniDV, and a variety of Macintosh photo and video editing software.
The SIPB office, next door to the Student Center cluster, also has two color scanners with document feeders. Feel free to drop by whenever we're open to use our scanners. You may want to call ahead (3-7788) to check whether the office is open.
If you'd like to print in color, you can use the printer "w20color" in CopyTech in the Student Center, or "echo" in 37-312.
