Not sure if this is related but we have also been seeing strange things with printers for the last week or so.
Printers that have been working fine for a long time are now coming up with messages that it cannot find the driver. After reconnecting to the driver it will print a page and then stop again. Some have required that we remove the printer, driver, and port and then reinstall. The timelines don't seem to match with any patches we pushed with LANDesk. A few of the machines did have a click2run update run from Office 2013 just before the errors started but haven't been able determine if that is a possible cause.
