I have a Win 7 Professional 64-bit laptop that I use i three different offices with three different printers. I have installed all the windows updates and made sure all the drivers are up to date.
Indepndent of what I do or where I am, the Windows print spooler stops. I can restart it and restore the ability to print. I can go for days without a stop, or it can stop every five minutes.
I've tried several 'cures' from the internet but the problem always returns.
