If you happen to have an older Mac with RJ-45 ethernet at hand, you could connect it to the iMac using a crossover cable and connect the HP printer to the older Mac by LocalTalk cabling. On this Mac you also install LaserWriter Bridge (current version 2.1, available at Apple for download). LaserWriter Bridge is unsupported software, but for me it works fine.
