I think it is 15 feet (~5 meters) for parallel. To go the distance you would need a parallel repeater or you could go serial with a drop in throughput. The HPLJII does not resovle device contention on its ports however, so you have to configure it for one port or the other (you can't have some jobs comming in on serial and others on parallel and have the printer switch automatically). To stick with parallel on the printer end you could use a serial-to-parallel converter (cost ~$60 (US)). This plus an auto parallel switch (cost ~$60 (US)) should do the trick and serial cable is cheap. The throughput would be limited to 19200 bits/second however. To get parallel throughput (230000 BYTES/second) you would have to buy more expensive cable and a line extender (a.k.a. repeater)(cost ~$90 (US)). The external ethernet lpd servers start at around $250 (US). The throughput is 10 million bits/second to the server (shared across all devices on the segment), but from the server to the printer it is a regular parallel connection. Ethernet is probably the most flexible in terms or wiring the system as well. _____________________________________________________________________ Don Gaffney (http://www.emba.uvm.edu/~gaffney) Engineering, Mathematics & Business Administration Computer Facility University of Vermont - 237 Votey Building - Burlington, VT 05405 (802) 656-8490 - Fax: (802) 656-8802
