The computer pool has color and black and white printers for students. You have a monthly budget of 6€ for printing with these printers. Black and white pages cost 5ct each and colored pages cost 10ct per page. Thesis can also be printed via the Poolmanagers outside of this budget. Contact them some time in advance to print your thesis.
You can print remotely or directly from the computer in the pool. The printed pages have to be retrieved by you in both cases. In the following we will show how you can print a document from you own computer.
- Copy the document to your pool account with
scp
. - Login to the pool with and then on to a physical machine with
ssh
. - Print the document with
lpr
.
These 3 steps could then look like this:
# Copy the document to your pool account
scp @login.informatik.uni-freiburg.de:~
# SSH to the pool login server
ssh @login.informatik.uni-freiburg.de
# SSH to a physcial machine from the login server.
# The physical machines go from 01 to 63. You might need to try some until you find one that is on.
ssh tfpool
# Print the document. is the name of the printer from the table below.
lpr -P
or as a oneliner:
cat .pdf | ssh @login.informatik.uni-freiburg.de "bash -c 'ssh tfpool lpr -P tfppr1'"
