| |
Hi all :)
I have a Lexmark E312 laser printer, which comes with both a parallel port and an USB port. It interprets PostScript, so when I print I simply 'cat' the file to the printer device (together with some codes, quite simple). This method works smoothly when using the printer through the parallel port, no problem, but when I use the USB port, sometimes I get the following:
kernel: host/usb-uhci.c: interrupt, status 2, frame# 682 kernel: printer.c: usblp0: nonzero read/write bulk status received: -110 kernel: printer.c: usblp0: error -84 reading printer status kernel: printer.c: usblp0: removed
I have shown one of each error messages I get in my system logs. Normally I get a couple or three of the first message, a few of the last and a good bunch of the another two. Whenever I get the message about the 'bulk status', the printer dies and I must turn cycle it.
I'm using kernel 2.4.21, if this matters...
Since the parallel port works OK, I know the printer works. So the culprit must be:
- The USB interface of the printer. Not likely, but... - The driver for usblp0 - The driver for USB uhci - Me (most likely)
Is that a symptom of misconfiguration? Must I do anything more than a simple cat for printing trhu USB)? Can I tune anything for getting better timing or the like (if it is a timing problem, of course...)? I thought that the printer was broken, but when I tested printing through the parallel port and it worked...
Thanks in advance, and sorry if this is documented, I haven't found any information about this :(
