The lab is on a separate network hub already. The time to print images, as well as the quality of the print, is an art. Other traffic on the network. That example has many of the steps in the printing process that need to be checked. Assignment time lines and sessions should reflect that reality, if non-example printing is desired.
Many classes have assignments turned in electronically.
We have a unix turn in program, and often have set up one-way drop folders for mac users. If the print presentation of electronic images is the problem, then maybe collecting the electronic image is a better answer. We are more than glad to work with instructors on issues like this. Ok, This really needs some solving. They are stuck with two terrible choices.
