I have had an issue where I have been unable to install 32b drivers on a windows 2008 64b server. I have log on to the suppliers website download all version of there drivers and none of them works. This stop me rolling out printer using scripts or preference to 32b clients.
Finally I had a conversation with a Brother printer tech and we solved the problem in Minutes, after working through the problem over a few days.
The issue is with the 64b drivers. What happen is that when you install the printer it downloads and installs the Windows drivers for the printer rather than the manufactures drivers. There is a mismatch in the settings that stop the server recongnising the 32b drivers.
