Printing from MicroStation printer.pltcfg set up with the path to the print server (on Windows Server 2008) only works from half our workstations. We are all using Windows 7 64bit Operating Systems. If the printer is set up as a local printer and the MicroStation .pltcfg adjusted to the local path it will print to it 100% of the time.
Make sure Windows 7 64bit Service Pack 1 is installed on all the machines where MicroStation SS2 is installed
