Hello, I have a problem with an Epson Stylus Photo 890, USB, which most of the time is just fine but occasionally hangs itself part-way through a job. No data seems to be sent to the printer any more, at least the sending process doesn't terminate, until after half an hour or so lprng removes the processes and sets the job status to error.
Can anyone tell what the likely cause is? How to go about debugging it? The debugging option are a bit unclear to me, the docs are a bit brief. is "lpc debug queue 5" the same as as lpc debug lpr+5,lprm+5,network+5,..."? Does lpr+5,network+2 set the debug level for "lpr" to 5, for "network" to 2, and all others to 0? With lpc debug all 2 nothing is written to the log at all during the 20min the job needs to print, which means what I am really interested in is missing. Which name exactly do I use? I need to trace the unspooler and how it sends the data to the printer. lpr, lprm, etc are of no interest. Which settings should I use? The job status after submission (empty queue) is "active". This seems to be checked at each lpr, lprm. After perhaps 1-3 minutes have passed, the status changes to "stalled" with either an lpr or lprm, but sometimes it stays "active". Is this normal? The jobs seem to complete fine.
