I'm going from memory here, but I think a 51 is a buffer overflow,
caused
by a miscommunication between the printer and host. The host isn't
getting
the message from the printer to stop sending data when the printer
buffer
fills up. In our case, the printer was not configured properly.

Hope this helps.
