Hi folks. This is a problem with the sequence the jobs are printed. If this is not the appropriate conference, please let me know asap. There is a customer that has defined two different queues in /etc/printcap file, but these two queues point to the same printer. LP5 uses /dev/tty08 and points to D90TL server, port 5 LP2 uses /dev/tty07 and points to D90TL server, port 5 This is because he needs different filters, while printing different types of files. Everything is working, but he said that the time sequence doesn't work properly. That is if you start to print in lp5, and let five files in /usr/spool/lpd5 spool directory, you can see one printing and the others wainting, and until here nothing wrong. Now you start a command to print in lp2, this file that is wainting in /usr/spool/lpd2 spool directory will print prior to the second in /usr/spool/lpd5, why ? Does it has something to do with the queue number (2 or 5) Is this a supposed behaviour ? Thanks in advance for any help. Regards. Manoel F. Abreu Neto(MCS/DEC-Rio)

| 8727.1 | Patches? | NETRIX::"[email protected]" | John McNulty | Thu Feb 06 1997 09:51 | 10 |
What version are you running? There is a patch in the V3.2C -> V3.2F patch kits to fix print queue order problems. Though whether it fixes your problem is another matter. There are examples in the README section of how to reproduce the problem and what the results look like before and after the patch is applied. Try the test for yourself and see.

| 8727.2 | Thanks and little more detail. | VAXRIO::63222::Manoel | Thu Feb 06 1997 15:57 | 10 | |
Ok, thanks, I'll verify about the patches, but in this case I think it won't solve, because there are two different spool areas pointing to the same printer, and one has always bigger job numbers than the other. I tried to use the same spool area for those two different queues, but another problem raised, some times text files don� come out, only header prints. MFAN(MCS/DEC-Rio) | |||||
| 8727.3 | scheduling sounds normal | R2ME2::DEVRIES | downsized: your footage may vary | Fri Feb 07 1997 09:15 | 9 |
Most queue controllers order jobs within specific queues only, not between different queues, which the queue controllers may not know ultimately refer to the same printer. And most device controllers allot access in round-robin order, because they don't know about jobs that haven't been sent to them yet, or about submission times, etc. Though I don't know the specifics of these components in Digital UNIX, your description of the scheduling seems to fit this standard approach. It's exactly the way I'd expect them to operate. -Mark | |||||
