Long delay before printing last page on HP LaserJet 1150/1300/1320 (usb backend)

I have many old HP LJ printers (1150/1300/1320) and there is very long delay before last page prints (5-10 minutes) with libusb-based usb backend. Usually this last page is also corrupted. It looks like STR #3405. I can't use hp backend from HPLIP, because it is small embedded system and I want use everything as generic as possible. Decreasing buffer size as in r9448 does not work for me. Usblp-based backend works perfectly.

Inserting sleep(1) before calling close_device() in usb_libusb.c fixes this for me.

Looks like this should be implemented as a new USB quirk type, perhaps named "delayed-close" which lets the backend do a sleep(1) before doing close_device().

Instead of sleep (1) ti will be better to call fflush prior tp close_device

I'm not sure that fflush will work because I've captured USB traffic with and without sleep() and the only substantial difference I've found was time delay before switching altsetting back. I think it is a hardware bug, and a new quirk type will be good.

It has been a very long time, but I recall some printers from this period where the coordination between the PDL language interpreter and the USB subsystem had some issues, and that could cause buffer flushing problems in the printer. Making sure that the jobs were well-formed as far as the PCL5 or PJL language reference manuals were concerned may help; for instance, including leading / trailing UELs to "thump" the language interpreter, which may cause buffer flushes between the subsystems.

Please provide the USB vendor/model IDs so we can populate the quirks file appropriately.

Maybe there are more affected models, but I've seen only these.

Dear Mike,

The same delay-close problem exists on HP Laserjet 1160.
Adding the following to org.cups.usb-quirks has solved the issue:

# HP LaserJet 1160 (Issue #4549)
0x03f0 0x1e17 delay-close

Could you please include this in the future versions?

Gabor
