The majority of our users are experiencing an issue with our Network Printers. Throughout the day, users will have to restart their Printer Spooler service to bring the Printers back online on their machines. It doesn't happen to everyone at the same time, it is an individual problem. The actual printers appear Online and show no signs of errors in Event Viewer. We have multiple brands of printers: HP, Samsung, Canon, Kip, Savin, Ricoh... all with updated drivers. Even the "Adobe PDF" print driver becomes offline when this happens. The users are currently running Windows 7 Enterprise x64. The print servers are online and report no signs of issues. All three of our offices (different print servers running 2008 R2) experience this issue. All with the same image. There was a post to add a registry file to resolve the issue. After this fix, the problem still occurs, just not as often: 1. Click Start, click Run, type regedit , and then click OK . 2. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print 3. On the Edit menu, point to New, and then click DWORD Value. 4. Type SNMPLegacy, and then press ENTER. 5. Right-click SNMPLegacy, and then click Modify. 6. In the Value data box, type 1, and then click OK. Note:This hotfix does not work if the SNMPLegacy registry entry is set to 0. If this registry entry is set to 1, the print queue status is displayed as "Ready" instead of as "Offline" when a printer device does not respond to SNMP commands. 7. Exit Registry Editor. This fix only helped for a few days. After this registry file was applied, two days later people reported the problem again. We have other users running Windows 8 Enterprise x64 and have reported no issues. And guidance would be appreciated.
