Are you _required_ to use USB?

If I were you, I'd stick an an Ethernet connected RS232 port widget on
the printer and talk to it via Ethernet.

OTOH, if it's only 35 feet, you could just run a serial cable to it
(you might need to add a serial port to your host).

The LP2844 has a serial port, right?

Using USB for anything other than keyboard and mouse is asking for
trouble.  Due to MS/Intel's backing, and a few other historical
accidents, USB beat out _far_ better options like Firewire and gets
used/abused for all sorts of things for which it's not really
appropriate.  But, it's still a horrible protocol and oughtn't be used
for anything where the Microsoft motto of "it sort of works most of
the time" isn't good enough.
