Hello Steve Bump
Welcome to Microsoft Community.
I can provide two steps for you to follow to put your computer to sleep mode again, and wake it up and see if it will print again (we recommend repeating this twice to make sure it is completely gone)
- Win+R and type services.msc, find "print spooler" in the list of services, right click on it - properties, set the startup type to "Automatic", then click OK to close it.
- WIN + S search control panel, open the device and printer, select printer properties - device settings - installable options, disable the "printer status notification", for different brands of printers and driver versions of this portal interface may be different.
if you can not find the portal, you need to contact the manufacturer of the brand to obtain the portal, only need to follow up to confirm that you can find Just make sure that you can find the "Printer Status Notification" function and disable it.
If anything is unclear, please do not hesitate to let me know.
