Just to drop down how I get a 10 years old printer server installed on Windows Server 2008 R2.
PCI Fast Ethernet PrintServer Mini300plus
The driver is too old and cause error during installation on Windows Server 2008 R2.
After checked the manual carefully, it is found that the printer server actually support LPR (Line Printer Remote). Just to add the feature LPR Port Monitor on the server, follows the manual to create a LPR port during addition of the printer to the server and done.
