Hi, the logs from the 4200F seems similar to those from the 5600F, and
maybe this is something like the canon630u backend protocol using the
GL640, judging by the 8-byte command sequences often beginning with
either 0x40 or 0xc0. Or maybe something else----I am not familiar with
that protocol.

Thanks for the information,
