1. Printing to usb printer
Basically how do you print to one of these directly w/o using the win32
routines. This is in the docs
"CON" - the console (screen)
"AUX" - the serial auxiliary port
"COM1" - serial port 1
"COM2" - serial port 2
"PRN" - the printer on the parallel port
"NUL" - a non-existent device that accepts and discards output
but I don't see how to print to a USB printer. Maybe "USB"??

I don't think you can print directly - modern printers don't have the ability to
lay out the dots in the right places without software intervention. You need to
;
thru the Windows drivers. Look at the website below for a possible solution:

This is a bar code printer which takes ascii character commands, so it is not
a bit map type of thing that a driver creates. I could put it on a parallel
port, but I would also like to print to other serial ports other than com1,
com2, etc...like a tcp port that goes to a print server.

George,
those device names are there for legacy reason, There is no "USB" as there
was no USB at DOS time.
To answer your question, it is easy to write to one of those DOS device from
euphoria. Simply open it like a file.
exemple:
atom fh
fh = open("CON","w")
puts(fh, "hello world\n")
will print "hello world to the console.
The same is true for "PRN", "COM1", etc...
