123	Unable to get scanline 0! when sending test page	Lewis Rosenthal		"ThinkPad T60
cups 2.1.3
HP !PhotoSmart P1000 connected via USB
Arca Noae USB 11.14
usbcalls 20140416
i686 arch

The summary may be incomplete. usb.exe simply sees:

usb://Unknown/Printer

whereas the same printer connected to my T43 (same cable) with Paul's cups 1.4 produces a more useful URI:

usb://HP/PHOTOSMART%20P1000?serial=MX0AG1D1V7HP

Same error (as reported in the summary) with Gutenrprint vs Gutenprint simplified.

Sending a test page from cups admin page results in no data being sent to printer and the error listed in the summary.

Sending data to the printer via WPS object (straight to USB) produces output (though raw postscript).
