Been away a while, so this is old, BUT:
Sending ASCII to a printer that doesn't have a raster processor, will
produce garbage. Generic ASCII strings sent to a USB, parallel, serial,
or SCSI printer are still just meaningless data unless the printer can
convert them to something. Most USB printers convert ASCII to individual
dots, not characters. So sending ASCII to a USB printer is like sending
PCL to an Epson FX80. It will just waste paper.
And the original question was about redirecting an LPT: output from LPT1
to USB on a laptop with no available LPT ****ts. So the above information
still stands. A USB printer may not be able to function with LPRINT
period. See below...
