Academic lab printing disruption: Friday, April 29, 2016

Posted on April 29, 2016 by Casey Carvalho

At approximately 8:50am on Friday, April 29,  academic lab printing started experiencing slowness when downloading a required print  driver at user login time. The issue manifests itself via  a pop-up message indicating that the Windows Printer Installation is Looking for a driver…  If the pop-up is not closed, the driver eventually installs after a few minutes.   If it is closed by the user, the driver download is interrupted and printing will not function afterwards.

Technical staff are investigating the problem and will provide and update once the problem is fixed.

Update – April 29, 4:45pm: The networking group is still investigating the problem.

Update – May 3, 4:30pm: After extensive trouble shooting by technical staff, the root cause of the problem has been narrowed down to an automatic update to the anti-virus software.  The anti-virus software vendor has been engaged and we expect to have a resolution shortly.

Update – May 11:  An update released by the anti-virus software on Friday May 6th resolved the issue.

We apologize for the inconvenience.
