Operation could not be completed Error 0x000006ba restarting Print Spooler

Using your office printer to print something is usually a regular task, but only if everything goes correct. If even a single thing goes wrong, the pages won’t be printed and you will see this error message “Operation could not be completed (error 0x000006ba). Please restart the spooler on the server or restart the server machine.” The best solution for this issue is stated directly in the error message.

Workarounds –

1. You should restart the system once and retry the printing operation.

2. If you are using an Office printer, ensure no other printing process is happening. That may stall your work and show you the error message.
