Same problem for me. I have an old parallel-only printer. It has been
working with a dedicated printer server, but the printer server died and
the PC has no parallel port. So I connected a USB-to-LPT cable. As I
attach the cable /var/log/syslog shows:
parport0: fix this legacy no-device port
Having very similar issues to carlossl.
Running Ubuntu 13.04, an EPSON LQ-1070+ (running the LQ-570+ drivers, which
work fine) and a QinHeng Electronics CH340S USB to parallel connector.
On a 12.04 machine I could use the printer with the regular parellel cable.
The only real difference is that
Hello,
First of all, thanks a lot for your efforts to improve the community.

a USB cable.

I checked the cups log, these are the last messages in the file:

Unfortunately, a security update for cups was released that supersedes
the update in -proposed.
The changes in -proposed need to get merged with the security update,
and re-uploaded.

Yes, you are right, the files relevant for you are all i386.deb plus all
all.deb files. The other files are for other architectures or the source

This looks like a strange special case, as now even the usblp kernel

systematic investigation now. Perhaps we have a very bad interference of
instabilities of the adapter, the kernel and libusb. Now I need all

Thank you very much for testing. I have done an additional small fix as
the fix in my PPA still has a potential crash bug.
The final fix I have applied to Oneiric's CUPS package now and uploaded
the resulting package into the oneiric-proposed package repository to

I have uploaded a new version of the CUPS package (1.5.0-8ubuntu7~ppa2)
to my PPA now. It will take some time to appear there. As soon as it
arrives and got built by our build servers, update your system, and try
again.
After the update, remove any broken queues for your printer, and then

* debian/patches/usb-backend-libusb-1.0.patch: Migrated the usb CUPS
backend to libusb 1.0.x, as libusb 0.1.x is deprecated and not maintained
upstream any more.

Please update your Oneiric system now to get my updated PPA package and
test it. Depending on your result I will propose my fix for an official
update for Oneiric.
