Need help installing a network printer

Hi --

I'm trying to install a QMS 2060 printer as a network printer. The printer
is of pre-plug & play vintage. Prior to acquiring this computer, the
printer was connected via parallel port but the new computer doesn't have a
parallel port connection.

I have current Vista-compatible drivers installed and the printer is
connected to the switch. Another printer does print correctly using this
setup.

My problem may be that I need a specific, pingable IP address for the QMS.
I had one for the other printer that works because the vendor talked me
through the configuration years ago and I had written down that IP number.
How do I get or assign one for the QMS and what must I do afterward?

Have been to the QMS site but either the info there is insufficient or I am
not understanding it.

Thanks for any hints.
