This was my first thought as well... I'm having the same problem as the OP. My file/print server is running XP, and I can print to it from my desktop and my wife's laptop (both running Vista) with no problem. When I try to connect from my laptop with Win 7 (x86 Build 7000) I can see the printer when I click Add Printer->Network, but when I actually try to connect to the printer it fails with error 0x000046a.
I tried connecting the printer to the laptop via USB directly, and that worked fine after I installed the driver from Canon (MF4150 multi-function printer) for Vista x86. I don't know if all the functions worked, but printing was fine. However, as soon as I try to connect via the network, I get the error as described above.
All the computers are on the same workgroup, the Win 7 laptop is configured as being on a Home network, and I am able to browse/copy/write shared files on the same XP file/print server. I'm stumped... Of course the OS is beta, so it's not the end of the world. :)
