USB printers install to their own port. THe HP LaserJet 1200 installs on the port DOT4_001. If the USB printer is shared in Win2000, the computer connecting to that share uses the same port. If you change the port ont he WS accessing the share, it will change the port on the WS that shares the printer, as well.
You can connect to the printer by browsing to the correct WS in My Network Places, right-clicking on the shared printer and choosing CONNECT. In Win2000, that’s all that’s needed.
