You can print from the library computers by logging into your Schoology account or by email as a PDF to your Gonzaga Prep email account. There is one printer in the Tech-Center shared by all students and teachers. This is heavily used during the morning break, so plan accordingly and try to print before school or during lunch. The default is to print two-sided. If you need to print one sided then click off two-sided in the print window.
Make sure you log off when you leave the computer. Otherwise, the next person that sits down to that computer will be in your account.
