Windows Ultimate 7 SP1 breaks printer sharing with Vista

[rconfused]

I am running Windows 7 Ultimate and sharing a printer to other laptops running in the household using Vista and XP. I installed sp1 last weekend and then laptops stopped being able to print. Spent 3 hours on it yesterday and finally rolled back and things are now working again.

I did notice that after sp1 my home group had been changed back to the "MSHOME" default. After changing it back to the exiting name, I could see the network printer and also edit files on any of the machines I had set access for. I also could set the print on the Vista release and my desktop with 7 would work just fine so no network issues. When I moved the printer back to 7, the Vista laptop would get an error while trying to load the drivers.
Let me know if there has been another patch to fix this problem or if someone got it to work after installing sp1.

I have Win7 with SP1, Vista and XP on the same network, sharing two printers. I used the printer install disc on the machines, so that they had the necessary drivers. I share through 'workstation'. By trial and error, I was able to share the Win7 printer with Vista by turning on Windows firewall
