I have tested this on 10.6.8 server and 10.8.X server.
HP printers are fine.
All my Xerox printers (5790s, 5335s, 7855s, etc) don't work when adding the driver, sharing them out, and then a client tries to print with a 64bit application. I tested this in Google Chrome on my machine (Mac OS X 10.7.5) and it prints just fine, then when I try and do anything in Mail or Textedit it hangs, then tries to print two ghost "Printer Status" reports before my job, ultimately not printing at all.
Xerox phone support had no answer for me, and I've tried the latest drivers 2.94.3. (I've since downgraded to 2.84.0 for testing). My mac gets the correct driver and information from my print server but then goes nowhere. Has anyone ever heard of something like this?!
Typical procedure is as follows:
Download driver for printer.
Install driver.
Cancel the automatic discovery in the driver.
Open up System Prefs -> Print and Fax
Add LPD printer based on printer's IP address and share it out.
Client then connects to the printer "@ server name"
Client's computer sees the correct driver
Client cannot print
Clients are a blend of 10.6.X, 10.7.X, 10.8.X
Thanks
Console logs look "okay" from the user perspective. I've attached an image of what comes up in the printer queue on the client machines as soon as the print dialogue box is brought up.

I should also add that printing locally FROM the server from 64bit apps works just fine. Something happens when sharing the printers though, from every version of Mac OS X Server I have.
