We also just installed a Lanier LP 020c color printer...no such delays with. Everything we print goes to a RedHat 9/LPRng print server, which processes jobs and sends them out to the appropriate printer using port 9100/appsocket. (Our Tektronix Phaser 850DP met an early demise when some well-meaning users tried to unjam the printer and proceeded to break one of the paper-path sensors.) We do all our printer status and pagecounts via SNMP. I've all but given up on doing it any other way. Jobs go off to the printers, they print, then we do a page count query, calculate the number of jobs printed and finish. (Why would we take on such a massive replacement?

If it's on the Win2k clients (all SP4), let me know where the reg setting is. Jim, There is no way to change the behavior of Microsoft's LPR implementation. Imagine how bad it was when the buffer size was 4K instead of 30K. I can't find anything about BSD and the push bit delay. Here's an excerpt from some Linux source (I couldn't find anything else): + * LSB of 4-bit field is TCP PUSH bit (a worthless anachronism) and + * is logically part of the 4-bit changes field that follows. To determine whether this is the problem, you should use tcpdump on your BSD box and look at the timestamps on the packets. You may find that after a packet with a push bit, there is a delay before the BSD box responds with an ACK. 200ms may not seem like a long time, but at 10Mb it is. At 100Mb it's an eternity. If this turns out to be your problem and you can't find a way to tune the delay on a BSD box, then your only solution is to stop using LPR protocol from your Windows box. You will have to use Samba and SMB protocol. This is a good solution unless you are blocking SMB protocol to protect your Windows boxes. I suppose we should know better than to use a non-Microsoft protocol on a Windows box. Wait! I have another idea. You can use a third-party LPR implementation for Windows. There are several available. I'll bet they don't have this problem. Finally, if anyone knows how Linux (Red Hat, in particular) handles the push bit delay issue, I would appreciate knowing. -Rick -- |Rick Cochran phone: 607-255-7618| |Cornell CIT - Systems Operations - Net-Print FAX: 607-255-8521| |730 Rhodes Hall, Ithaca, N.Y. 14853email: [EMAIL PROTECTED]| - 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.

Re: LPRng: SLOW spooling of Word file containing 225 pgs of scann ed docs
Jim, Here's a note I posted to this list a while ago. Perhaps it is relevant to your problem. I ended up changing the push bit timeout from 200ms to 50ms on my AIX server. That sped up job transfer by a factor of four. -Rick Rick Cochran wrote: Here's a good one. Due to a performance problem with Samba, I encouraged all my users to switch to Microsoft's WinXP LPR, only to find that it was taking a factor of five longer to send print jobs to the server. Here's what's happening: An LPR transfer from Linux consists of a steady stream of packets with 1460 data bytes each. An LPR transfer from WinXP LPR consists of groups of 21 packets with 1460 bytes followed by a packet of 1340 bytes with the push bit set (total bytes = 30,000). The server responds to the push bit by waiting .2 seconds before sending an ack. All these waits slow the transfer down by a factor of 5 (on a 10Mb net). This is covered in http://support.microsoft.com/?kbid=816627 (ie. Be happy, it used to be worse). I would like a high quality alternative to Microsoft's LPR. Since our out-of-band Kerberos authentication method is likely to go away soon (because of NATs), I would _really_ like to have Kerberized LPR.

I have the following setup: Lanier 2138 RPCS Color Laser (same as Ricoh 3800CMF) Win2k SP4 RPCS driver v 2.67 (most current) Print via Standard TCP/IP Port OpenBSD 3.2/LPRng 3.8.21 OpenBSD 3.4/LPRng 3.8.26 Printcap entries (tried Friday) for the 2138, which seem to work fine for all other print jobs: :[EMAIL PROTECTED]:lpd_bounce :rm=xxx.xxx.xx.xx:rp=lp :lp=xxx.xxx.xx.xx%9100 :lp=xxx.xxx.xx.xx%9100:lpd_bounce=true If I use the above settings, printing the Word 2000 file through either OpenBSD box takes FOREVER to spool the temp file; I can ls the /var/spool/lpd/2138 directory and watch the file dribble in. I tried a 40-page chunk, which resulted in a 56MB job, with NO improvement in speed. It never got to the point where the job actually started to print. It was taking so long, I knew something was amiss and killed the job. I ended up setting up a Standard TCP/IP port directly to the Lanier, to see if it behaved similarly. NOT!!! The job started spitting out as soon as I clicked on the Ok button in the Word print dialogue. It finished printing the 40 pages almost before I got to the printer. My lpd.conf is all defaults on both OpenBSD boxes. All other print jobs seem to print at full speed. What gives? Hi, When creating large/complicated print jobs (i.e. including bitmap graphics) there may be long time intervalls between data packets sent from PC to the server, timeouts can happen. To avoid these timeouts create the entire print job first before connecting to the print server. In the printer properties go into the spool settings and turn Start spooling after last page is finished on. The exact text may vary, I have a german Windows on my PC. I tried that, and Print directly to the Printer with the same results. Make sure the format for the queue is literal (binary) so the print server does not run filters on the print job. No filtering is being done, and the Print Processor is set to raw on the Win2k box. If these hints do not help we need to find out whether the problem is related to transfering the print job from the PC to the server or to sending from server to printer. It's from the Win2k PC to the server; it never finished spooling, so it never went to the printer. Sending it directly to the printer's own lpd, with the PC set to the default of Start Printing Immediately did exactly that. The only changes in settings were using raw protocol instead of lpr, and printing to port 9100 instead of the queue. The 2138 has a hard drive, and printed at full speed-no dribbling of the job. Why not just print directly to the printer? Because...the Ricoh/Lanier print server has an annoying tendency to go off into la-la land if multiple users/drivers are talking to it. I can crash it just by sending a PS job to it; within 4 print jobs, the queue is corrupt and the printer has to be reset. Sometimes I had to reformat the hard drive just to force a rebuild of the queue structure. I finally troubleshot it down to a decent solution; use ONLY the RPCS drivers, and use LPRng to feed it the jobs. Now it prints all day, every day. I can use holdall while changing out fuser oil rollers, etc, and noone knows the printer's been down. I call the 2138 The Chipper; feed trees in at one end, and stuff comes out the other... Print the print job to a file, transfer the file to the print server and try to print using lpr.
