Neither of these definitions/discussions is real useful, I'm afraid.

The DOT4 standard is used for most multifunction devices--perhaps whether
connecte via LPT or via USB--not sure--definitely when connected via USB.
If you look at properties of the printer, there is often a PORTS tab which
shows the name of the port that the printer is connected to--that's what you
need to look at to determine this issue.

I've a USB printer at home HP CP1160 (no longer made) which uses a USB001
port, so it redirects just fine. Some users in an office I work with have
Laserjet 1012's which are also simple printers with a USB connection.
However, their port is defined as DOT4 and requires the KB article
workaround to redirect for RD--it does work, once applied. The driver has a
status applet which talks back and forth to the printer, and I suspect
something about the DOT4 standard makes that job easier--there's no
multifunction capability in that printer.

The other way to determine the issue is:

1) is the printer USB or LPT or COM?
2) are there event-log entries at the host indicating a lack of the proper
driver for the printer?

If 1=USB and 2) shows no entry, then the port isn't being redirected, and
the chances are that the workarounds specified in:

http://support.microsoft.com/default.aspx?scid=kb;en-us;q302361

will be both needed and effective. You must reboot the CLIENT machine after
applying the registry change (to the client machine!) specified in this
article. And, even with that change, some users have reported failures with
multifunction devices--don't have a handle on whether it is a particular
vendors drivers, or what.
