Last week I upgraded from Windows 8.0 to Windows 8.1.
Yesterday I wanted to print something and the Print button was disabled on my printer. I checked some other printers and some of them had also the print button disabled.
net stop spooler
net start spooler
restarting the spooler did not help. The only way I could get it working again is by reinstalling the (virtual) printer(s).
(I didn't have this problem when I upgraded from Windows 7 to Windows 8.0.)
In the event viewer I could not find any errors related to some printers not working.
Now my question: What is changed in Windows 8.1 that makes that some printers got the print button disabled (forcing me to reinstall them)? (Does Windows 8.1 introduce new checks? Does Windows 8.1 require specific configuration settings? Does it overwrite specific files?)
Windows 8.0
andWindows 8.1
I have found that the drivers are basically not compatible with one another. I know this is at least true for the video drivers because of DX 11.1 not sure what changes Windows 8.1 made to printers. Make sure you only use drivers that specfically state they support Windows 8.1
