How well do USB -> parallel adapters work for printers?

[Bill Moran]

This will be FreeBSD 5.4 machine.

I need to hook a printer to a server (actually, it's a "plotter", an HP
inkjet plotter).  The server doesn't have a parallel port, and the printer
doesn't have a USB port.

The guy who provides our hardware recommended a USB -> parallel adapter,
but I've got no experience with these.  I've been warned about USB ->
serial adapaters and how the translation isn't always 100%, so I'm
trying to gather some information before I go forward with this plan.

Anyone use one of these?  How well do they work in general?  How well
do they work under FreeBSD?
