We have several shared printers on our windows server 2012R2. It was working fine so far but recently since last few weeks all of a sudden, all printers appear offline on the user's computers. We have windows 7/8/8.1 and 10. All the printers show offline on all the computers (200+).
Tried installing all the available updates on the server but the issue still persisted.
On some users computers, we installed the printers manually and some were installed with Group policy. The problem affects all the users and all the printers. We are using Ricoh Universal print driver, HP Plotter driver and Xerox model specific driver.
The only solution so far is to restart the spooler service on the server, after which all the printers appear online.
Right now a windows task scheduler has been created to restart the service every 30 mins but the issue is still sometimes encountered just after 10 minutes of service restart. Attaching the installed updated on the server.
Requesting assistance if anyone has encountered anything similar.
