Printers
To install the NTNU printers is usually only necessary once. Information about the student allowance for printing and prices for printing and copying for students can be found here. Tutorials are provided by NTNU Innsida.
Your nearest printer can be found via MazeMap. Find the building you are in and search for "Åpen tilgjengelig skriver" and you will see which printers are located nearby.
Recover overwritten/changed/deleted files from your home directory
The IT helpdesk has made an article on how to recover old files (up to 10 weeks) from your storage area at NTNU. This is a really nice feature, and can save you a lot of work if you are unlucky.
