These issues with local and network printing is now causing major issues with local printing too?
Printing directly to local printer without a print server has become unstable. My resolve is to uninstall print drivers and re-install printers by IP
Shared printers across my network are still non-responsive and cast errors on the connecting local PC's with both updates KB5006670 & KB5005565 installed .
Appling this fix to the shared network printer PC
regedit
=KEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print
