Printer USB port

[kim]

Hello

By now, I write

open "LPT1" for output as #30
width #30,255
....

But, I buy a new printer without paral.lel port, it has a USB port only.
I can't write the command "LPT1" .How can I do it. Also I can't make "Type
AAAA > USB"

Thank you

Quim

Possibly because LPT1: is the parralel port, but your printer is
connected to the USB port. You woun't be able to use most USB printers
from a DOS program unless the program is running in a virtual machine or
command line window.

Many of the printers sold today require some version of Windows, Linux
or Mac O/S. One of the ways printer manufacturer's have been able to get
their manufacturing costs so low is the elimination of much of the
circuitry in the printer's control electronics. Code in the O/S's
printer driver has replaced much of the function of the printer
electronics. The VERY primative BIOS functions that MS DOS uses just
aern't smart enough.

In general, you cannot access USB devices from DOS. The USB device requires
a device driver from the manufacturer, and manufacturers will not support an
OS that isn't current (read: Windows or Linux, in general).
