Amazing, I had no problems getting this printer hooked up with the Beta or RC, but now with the RTM it just won't work. I can install the driver from the MS catalogue, and get a pretty icon in the Devices & Printers panel. If I right click on it I see all the relevant settings for this printer in properties. But when I try to print a test page I just get a popup telling me I have an 0x0000007A error. Unlike other reports I have seen associated with this error, it does not result in a BSOD. So, not sure who is to blame here. HP for a duff driver, or MS for a bug in the OS. I checked the event logs and could see no entry for it any of them, so I can't tell what the additional parms are that go with this error to help diagnose it. The printer is connected to the network via an ethernet cable to the router. There are three other computers attached to the network that happily print to the same printer, two are running XP, the third Vista. It is only the W7 PC that can't use it. Anyone got any ideas? TIA.
