The USB printer driver deliberately disables bulk reading from a variety of HP printers. The reason is explained in a comment in the drivers/usb/printer.c file. The kernel message is just a FYI. I have had good results printing to an 832 and 895 which also trigger the message. -- SP ------------------------------------------------------- Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
