Is port redirection for USB printer bi-directional?

[Justin Huang]

Hi,
I'm developing a printer driver. The printer driver needs to read status
from the printer in order to do some kind of control and status reporting.
The status information is read by language monitor of the printer driver. My
problem is that when I work in the remote desktop session and try to make a
print to my local printer via the redirected port (TSxxx), the language
monitor couldn't read status information from the port. Is this normal?
The local printer is connected with USB. I'm using Windows XP professional
as the remote desktop server. Any suggestions?

Best Regards,
Justin Huang.

Redirected printers do not support bidirectional communication

Ratnest,
Thank you for the answer. Now I can stop trying it.
Here I got two more questions:
1. I heard that Citrix Presentation Server (or XenApp) is running based on
Terminal Server. Does it mean that redirected printers by Citrix do not
support bidirectional communication either?
2. I have been looking for a formal document to prove that the redirected
printer does not support bi-di communication. We need it to show our
customers and tell them some things can not be done without bi-di. Do you
have any links for us?

Thanks again!
