Printing issue is solved. Helpdesk knows the solution, in the process of making instructions that can be posted at printers/distributed to teachers.
Last year, a high impact vulnerability was discovered with Windows that allowed attackers to take over an organization's entire infrastructure using the organization's print server. In response, Microsoft has tightened down printing considerably , requiring elevated rights to install printers. This is a huge pain for our students, because that means to print they have to have a printer installed by someone in their building with admin rights.
Solution:
We're at working trying to make the primary printers at each school self-installable by students. We've had some successful proof-of-concepts, but our attempts so far haven't worked with PaperCut, our printer management software. This would prevent students from having printing limits, and they would be able to print anonymously.
Status:
We're actively at work on this problem
