Printers in departmental computer labs may be unavailable
Who: Printers in departmental computer labs and instructional spaces

Timeframe: on-going from the start of the semester

Status: In progress

Over the course of the pandemic, printers in computer labs across the college were infrequently used and many are in need of repairs, supplies and replacement parts, or other attention. Engineering IT Instructional Services is experiencing a high volume of requests this semester and it will take several weeks to return the many printers to working condition.

Additionally, the security vulnerability known as PrintNightmare was recently patched by Microsoft, which frequently results in limited or broken printing ability. Even printers in working condition and computers needing to print may require direct attention before full printing capability can be restored. The campus security team has released a statement about PrintNightmare.

Thank you for your patience during this time.

Alternative Solutions: Print to another known working printer, like EWS printers or department administrative printers until the in-lab printer is working For specific issues or concerns, please report them to engrit-help@illinois.edu
