Well, the 486 is doing much more than just sending data to the
printer.  It's building an image the resolution of the printer in RAM
and then dumping it using the Windows printer driver.  

I'd like to see the source for that driver, it could be usefull.
I have no idea how long the CoCo would take to do it but it would be
faster than that old driver.  The serial port was the limiting factor
with the old driver.  With USB the CPU would become the limiting factor.
