dotnet compact framework: Hi !

I'm developping using C# and .NET CF 1.0. I'd like to connect an USB
printer on my device. I know how to manipulate serial port COM1: /
COM2: but i've never tested with an USB port. Can I manipulate USB as
Serial port ?

Thanks in advance,

Vincent.

Not unless that device (printer) is installed as a serial printer. Almost
certainly it IS NOT. Instead it is a standard printer, and you would use
exactly the same methods that you would use if it were a parallel printer.
In fact, even if had been installed as a serial device, you still would
(normally) choose to use standard printer output, otherwise, you would be
bypassing the Windows print spooler, etc.

Hi Vincent,

Sorry, I misread your post, completely! I must have been asleep.

In answer to your real question.... No. The USB port is not a serial port,
and standard serial APIs cannot be used. In fact, there is nothing that you
can do with the USB port (except to use it for ActiveSync -- and, thereby,
use it for a network connection via TCP/IP, or from the desktop via RAPI).

First of all, you'd need USB host on your device to connect anything with
USB interface.

Most devices don't have USB host, only client, so USB connection is not
possible at all.

If your particular device has USB host, please contact printer manufacture
for Windows CE driver and SDK.
