We've switched to LPRng/ifhp for most of our campus printing. It's mostly working (aside from some hard-to-fix duplex problems). Most of our printers are HP8??0 printers with at least 32MB of memory.
We've seen a significant increase in printing time. That is, it takes a lot longer to print most documents. We're also seeing a lot of the 79 errors that others on this list have mentioned. I can understand delays between jobs: we're using ifhp to get page counts, so the printer doesn't receive the next job until the current one is finished (e.g. no multiple-job caching). What confuses me are the delays during jobs. It seems like the printer only receives a page at a time. A page is ejected, the data light blinks for a bit (10 seconds to a minute), another page is ejected, etc. Our old system was stupid, but it kept the buffers full and the printers busy, even when the pages had a lot of graphics. Is it possible that some part of the printing system is trying to "protect" the printer by only sending data a page at a time? Could the switching between Postscript (for the print jobs) and PCL (for the page counting, etc.) be causing problems (I suspect that this switching is accounting for some of the 79 errors, but I don't have enough data to prove it)? Might ifhp be attempting to get status information during the job? -willie -- "I can't give you a brain, so I'll give you a diploma" - The Great Oz ----------------------------------------------------------------------------- YOU MUST BE A LIST MEMBER IN ORDER TO POST TO THE LPRNG MAILING LIST The address you post from MUST be your subscription address If you need help, send email to [EMAIL PROTECTED] (or lprng-requests or lprng-digest-requests) with the word 'help' in the body.
