[Pkg-cups-devel] Bug#690982: Acknowledgement (Printouts are incomplete)

[Michael Biebl]

Some additional information:

I'm using a Canon PIXMA MP610 printer, attached via USB.

So looking through the diff between -1 and -2.3 the patch
debian/patches/usb-backend-further-enhancements.patch might
indeed by the culprit here. Reading through the patch header

 - Added the command line option "usb-no-reattach". With the option set
the usblp kernel module does not get reattached after a job has been
printed. Some printers cut off the end of the job or even crash by
re-attaching the module. This is a development/debug mode to test
whether re-attaching was the culprit of a problem. Users should
report such issues so that their printers can get added to the quirk
list.
- USB backend: Do a printer reset after each job, this makes the
Prolific USB -> Parallel adapter finally work (LP: #987485) and
makes it unnecessary to blacklist the usblp kernel module for some
printers (LP: #997040).


I've tried  "lp -d Canon_MP610_series -o usb-no-reattach=off test.pdf",
but that didn't seem to help.
I'm not sure though, if I have passed the usb-no-reattach option the
right way.

In the kernel I still got an entry like
Oct 20 00:39:39 pluto kernel: [ 2641.104790] usb 1-1.1.3: reset
high-speed USB device number 9 using ehci_hcd



On a different note: I don't quite understand, by you modprobe the usblp
module on upgrades, but not in the init script
.
If the module is needed, shouldn't you also load it when you reboot?
If it's not needed, why the modprobe?
