Having just upgraded to 2.4.21, the first time I tried to print, the
following happened. The printer started to print, but gave up after a
while and spat out just about 1" of image. Needless to say, it all worked
fine under 2.4.20.
Intel 82801BA based MB, running stock 2.4.21 (compiled with gcc 3.3.1)
with uhci driver (all on Debian testing)
This debugging code was introduced during 2.4.20->2.4.21, but I'm afraid I
don't know what the significance of it is. (Happens when td->dma_handle !=
(qh->element & ~UHCI_PTR_BITS) )
Can anyone tell me what's going on? I am happy to provide more information
as necessary.

This last stanza is then repeated, every 41-160 seconds, presumably each

I can't tell you what's going on, but I can explain the debugging
messages.

That's not an error; it's just alerting you to the fact that the transfer
being shown has already begun.

Each of these guys is a packet (the data is split up into 64-byte packets)
that has been transferred to the printer successfully.

This is the trouble spot. It's a packet that failed 3 times because the
printer did not respond within the timeout period or because noise in the
cable prevented the response from being received.

These are additional packets that haven't been sent because the transfer
was aborted when the trouble occurred above.

-110 is the code for a timeout error.

This indicates more communications problems. Have you checked that your
USB cable is okay? Did you go back to 2.4.20 to see if that still works?

Thanks for the detailed explanation. I am still trying to verify what
happens in 2.4.20. Unfortunately, in upgrading/installing the graphics
drivers to enable me to run 2.4.21, I am now unable to run X under 2.4.20.
I have a different graphics card on order.
Simple text printing (/etc/group, print size 1024 bytes) works under both
2.4.20 and 2.4.21, as does tiger.ps (print size ~31k), so I think it
unlikely that a cable problem is to blame, but I can't yet easily test a
large, complicated rendered graphic print on 2.4.20.
However, several reboots later, the original page is printing under
2.4.21, so I don't know now if there's a problem or not.

I can confirm that this does not appear to be printer related, this
nearly exact scenario just happened to me while running test3-mm2. So
I powered down the printer, in this case an Epson C82 being driven by
cups, and then rebooted to 2.4.22-rc2. Where it also refused to
print, until I went to the local cups page and "started" both
printers, which had been apparently disabled by the above failure and
it carried over the reboot from 2.6.0-test3-mm2 to 2.4.22-rc2. Once
the printer was 'started' then the 3 jobs I'd sent were spit right out
normally.
It appears that usblp still has problems as of 2.6.0-test3-mm2.

the last 2 lines were output when I turned the printer back on while
the shutdown was in progress.
All this because I wanted to print my flight itinerary for a
trip to Colorado expected to leave Sunday and be there, and out of
touch (probably, unless I can find a machine to take back to the
guest house), for 2 months. I hope I don't forget howto type by
the time I get back. :-)
And I hope 2.6 is a little closer to prime time by then. So far
its been hit or miss, but looking better with each test release. :)

There was a recent change to usblp for 2.6.0, reversing a prior patch
which broke the driver somehow. See
http://sourceforge.net/mailarchive/forum.php?thread_id=2931846&forum_id=5398
I don't know whether or not this change is already incorporated in the
version you're using.

I don't believe it is Alan, and it will now have to wait till late
October and my return from putting out a few fires at a sister tv
station.
By then maybe 2.6.0-rc3 will be out?
