I haven't seen any need for it yet.
The Postscript print driver allows the selection of lpr.device directly, so I didn't bother with any port redirection. It seems to be working well enough, though I have not had a lot of testing time yet.

I don't have any classic systems to test the printer with.
Lyle, I have PageStream and I believe it expects the PAR port, as does Final Writer. The others use the OS PostScript driver.
Mike, I have used up to 3 different networked printers with my Classic 4KT under OS3.9, but she sits in her box awaiting setup while I crank away on my X1000; I need more desk space.
My old HP 2605dn worked best with my Amy, but pushed out color duplex at a noisy 6 to 8 pages per minute (10 - 12 in B & W). I gave it way ;<(
