I am using OneCare printer sharing. The computer that has the printer attached to it is not the laptop. This is the configuration:
Laptop w/Vista Home Premium: OneCare Hub, prints blank page on Lexmark printer attached to PC1
PC1 w/XP Home: has Lexmark printer attached
PC2 w/XP Home: no printer, no driver installed for Lexmark printer, but prints fine via OneCare printer sharing
I didn't think the driver would need to be installed on a computer sharing the printer via OneCare. But I'll give it a try.
