[Coco] Serial to usb printers

[Luis Fernández]

Thanks 
I understand all that, 
have to plot each letter and besides you have to handle the USB protocol which is complex 
But the question is to the hardware connection, the physical connection, voltages etc. ..,
 is it possible?, 
need to interface?

> Won't work with a modern USB printer. Modern PC printers use the driver on the PC to do all the data work. The printer itself has no "brains". The CoCo needs a printer that translates the data to printed characters. You'd have to write a driver for a modern inkjet printer. No brains is why they are so cheap! Anything that can store or use raw data with a minimal driver should work, even a keyboard.

In other words, save your writing to a file then run the program to print the file. That way the print driver/program can have 100% use of the CPU -- the only practical way to print at a reasonable speed with a modern inkjet printer from a CoCo.
