DOT4 Ports

[johnw]

I have a HP 1300 laserjet installed on my XP por computer. I added another HP
printer (CM1015 color laserjet MFP) and it connects on a virtual USB port.
The color printer will eventually get lost and the USB port reports that
there is an "unknown device" attached. Is there a way to put both printers on
a DOT4 port and BTW what is the difference, both are connected via USB
connections.

I forgot to state that the 1300 is connceted to the "DOT4_001" port.

IEEE 1284.4 An IEEE specification, also called DOT4, for supporting
multi-function peripherals (MFPs). Windows 2000 has a driver called DOT4 is
a driver that creates different port settings for each function of an MFP,
enabling Windows 2000 print servers to simultaneously send data to multiple
parts of an MFP.

The 1300 is a multifunction device if you purchased the scan accessory.

HP has some documentation about unrecognized ports.
