I'd like you to collect a usbmon trace showing what happens when you try to print a two-page document. (Instructions for usbmon are in the kernel source file Documentation/usb/usbmon.txt.) Make the document itself extremely simple, like just a single line of text on each page. In fact, do this twice, once under 3.1 and once under 3.0, so we can compare the results. Also, please include either the "lsusb -v" output for the printer or else the printer's section in /sys/kernel/debug/usb/devices.
