Info

The lpNet log shows you when network programs such as lpNet are forked, and when connections are made with remote systems. This log shows the events when we tried to cancel a job that was not printing on a remote system (see Example 12-6). Example 12-6 lpNet log entry 10/24/00 10:37 c 12972 rs1230a.myco.com lpd retrying connection to rs1230a.myco.com 10/24/00 10:45 c 58614 rs1230a.myco.com ERROR: class=Fatal, type=Unix, trace=(contimeout/setjmp), Interrupted system call 10/24/00 10:45 c 58614 rs1230a.myco.com Abnormal process termination. 10/24/00 10:47 p 61398 Got a hit. 10/24/00 10:47 p 61398 Got a hit. lpExec 10/24/00 10:47 p 61398 Started child for rs1230a.myco.com, pid = 50990 10/24/00 10:47 p 61398 Into Polling loop. 10/24/00 10:47 c 50990 rs1230a.myco.com lpd starting (active) Checking the pstatus file The /var/spool/lp/system/pstatus file contains a status stanza for each of the printers. This file often has a line with the last failure as shown here: ========== net12 enabled accepting 972671048 971311069 NAK'd by remote lpd: waiting auto retry new destination 12.3.5 Is the LANG variable set right? If you try to print from a locale that has not been fully installed on your system, you may get errors, such as the one shown below: # lptest 10 10 | lp -d hp1 UX:lp: ERROR: 0920-054 There is no filter to convert the file content. TO FIX: Use the lpstat -p -l command to find a printer that can handle the file type directly, or consult with your system administrator. However, if you simply add the -L C flag, the file prints with no errors: # lptest 10 10 | lp -L C -d hp1 request ID is hp1-362 (standard input) 392 Problem Solving and Troubleshooting in AIX 5L
12.3.6 Cancelled remote jobs still queued When a remote printer is set up, and for some reason it stops printing when you cancel a job, the job is still visible to lpstat but shows a canceled status, as shown here: # lpstat -o all net12-359 root 110 Tue Oct 24 10:16:50 2000 canceled In this case, you will probably have to shut down the scheduler and restart, although it may be possible to kill the lpNet command that is hanging that port. 12.3.7 Printing to a file By printing to a file, you can see exactly what the virtual printer has added to the file that is being printed. With the lpadmin command, you can specify an output file with the -v option. The following procedure explains how you could use this to diagnose a problem: 1. Create a file in the /dev directory. The file must have permissions for the user doing the testing to use, therefore you can set the permissions accordingly: # touch /dev/lpx # chmod 600 /dev/lpx # chown lp:lp /dev/lpx 2. Create a printer to a file using the printer type, interface type, and content type that you want to diagnose: # lpadmin -m standard -T hplaserjet -I simple -p fileq -v /dev/lpx This may give an error if the lpx permissions are set to 777 or something else, but that is not a problem. For PostScript queues, you will need to specify type PS-b, because this uses lp.cat, while PS uses postio, which will not print to a file, but only to a printer. # lpadmin -m PS -T PS-b -I PS -p fileps -v /dev/lpx 3. Give the commands to have the printer accept jobs and enable the printer: # accept fileq UX:accept: INFO: destination "fileq" now accepting requests # enable fileq UX:enable: INFO: printer "fileq" now enabled 4. Print to the fileq printer with a test job and make sure there is data in the file: # lptest 5 5 | lp -d fileq -L C request ID is fileq-594 (standard input) # ls -l /dev/lpx -rw-rw-rw- 1 lp lp 222 Nov 01 12:34 /dev/lpx # cat /dev/lpx Chapter 12.
