problem with usb printer

[Alexander Best]

alright. here's some more information. when i attach the printer i get the
following output:

uhub_reattach_port:348: port 2 reset failed, error=USB_ERR_TIMEOUT
uhub_reattach_port:434: device problem (USB_ERR_TIMEOUT), disabling port 2
ugen0.3: <Samsung Electronics Co., Ltd.> at usbus0
ulpt_probe:472:
ulpt_attach:498: sc=0xc5f81200
ulpt0: <Samsung Electronics Co., Ltd. Samsung ML-1510_700, class 0/0, rev
1.10/1.00, addr 3> on usbus0
ulpt_attach:538: setting alternate config number: 0
ulpt0: using bi-directional mode

when i simply issue a print command using `lp file` i get the following
output:

ulpt_reset:164:
ulpt_write_callback:203: state=0x0
ulpt_write_callback:203: state=0x1
ulpt_write_callback:203: state=0x1
ulpt_write_callback:203: state=0x1
ulpt_write_callback:203: state=0x1
ulpt_write_callback:203: state=0x1
ulpt_write_callback:203: state=0x1
ulpt_write_callback:203: state=0x1
ulpt_write_callback:203: state=0x1

at this point the printers light flashes a few times indicating that it's
about to print. but nothing get's printed. `lpq` tells me that the job has
been finished succesfully.

the problem where the console get's flooded with warnings and the printer's
led reports an error appears randomly. i'm trying to figure out how to exactly
to reproduce it.
