I had the same problem as the author with my HP 1020 LaserJet, except it was using it with a Mac ;) First I upgraded my AirPort Express and I lost the ability to print via WiFi. Then I upgraded to Leopard/i386 and making the printer work was akin to voodoo — I had to go through some tedious process of first installing the PPC drivers, setup the printer, and then overwrite the drivers with i386 versions. This got weirder and weirder, and eventually I gave the printer away and bought a Canon.
