Remote printing and print server printing requires the printer port be 
interrupt driven.  Some manufacturers of I/O cards have taken shortcuts
and not made the port interrupt driven because DOS polls the parallel port
and does not use interrupts.  If you experience slowdown when printing to
a remote or printserver port, change the configuration to not use interrupts.
This will match the software with the hardware and should improve performance.
If this doesn't work, try swapping the I/O card for one that uses interrupts,
and switch the software back.
