I am running Windows 7 beta, testing to see if the product is right for a client. The client has an Epson 3800 photo printer and uses the print preview function. I have installed the latest printer driver for Windows 7, the latest NVidia driver available (ver. 8.17) and the system blacks out, and sometimes recovers, but usually reboots. I get and problem report for the Epson print preview on occasion, but not always. The last reboot did not report any error for me to figure this out. Is anyone having this issue and have you found a solution? I am going to try printing without preview. FYI: Printing works if print preview is not used. Anybody have a clue as to the cause of this?
