Ubuntu 12.04 64 bit (also 32 bit is affected)
Zebra LP 2844-Z USB printer - connected with a generic "raw queue" driver.
usblp0 appears to disconnect after every print job and then automatically reconnect after 8 seconds. The next job to the printer won't print until it is reconnected. This is a problem for us in a high volume printing scenario.
Here are messages from syslog:

Note the 8 second pause between the first and second messages.
Not sure where the disconnect is coming from.
It doesn't appear to be hardware related as I have the problem with various combinations of printer and computer.

[IMPACT]
On some printers it can happen that with Precise's new libusb-based USB CUPS backend there is a small delay of around 8 seconds after each job. In environments where printers are continuously printing small jobs (~1 page each) this is a serious impact on printing performance.
The USB backend in the proposed package has a configurable option to turn off the bi-directional operation of the backend (sending print data and also reading answers of the printer). With uni-directional printing (only sending print data) the delay disappears.
Uni-directional printing can be set manually. We will give instructions in the Release Notes of 12.04.1.
[TESTCASE]
Unfortunately, for reproducing this bug one needs the actual printer.
Connect a printer with the problem to the USB port of the computer.
With current Precise you get the mentioned 8-second delay after each job when you print several jobs one after the other. If you install the proposed package you can suppress bi-directional printing via
lpadmin -p <queue name> -o usb-unidir-default=true
Now the jobs get printed directly one after the other.
[Regression Potential]
The patch looks perhaps more dramatic than it is. This is because several code sections are put into "if" blocks, indenting all the (unchanged) code lines. This especially happens because now we suppress using the back channel for selected printers (and also printers which claim to be uni-directional only).
The code was developed in several steps and uploaded step-by-step to my PPA. There the reporters of the bugs covered by this SRU and some additional bugs (bug 902535, bug 995111) tested it intensively. They did not hit any regressions compared to stock Precise or the first CUPS SRU.
The code is also applied to the CUPS package in Quantal and this also did not cause any regression bug report yet.
I have tested the code on four HP printers (HP LaserJet 3390, HP Color LaserJet CM3530 MFP, HP PhotoSmart C8100, HP PhotoSmart C5200, all on direct USB) and one Epson printer (Epson Stylus Photo 880, both direct USB and parallel with Prolific USB -> Parallel adaptor) and all work fine, no regressions.
