as stated, set the printer up as remote. be sure to name the print queue on HP the same as the print queue on the emulex. You can telnet to the emulex, or serial attach an ascii terminal to it and log in. Then do a "show queue" to see the current queue names on the print server. These are configurable, so you can change them. The documentation on the Emulex web site is quite thorough, I've used it at a previous job with good results.
Good luck,

the future will be a lot like now, only later
