[Coco] Serial to usb printers

[Chad H]

Umm "-- the only practical way to print at a reasonable speed with a modern
inkjet printer from a CoCo." ???

Not necessarily, depending on what is 'reasonable speed' in your perception
and not if your fortunate enough to have a serial-to-parallel converter and
a inkjet printer that has the 'brains' to accept ASCII text & codes like you
say.   I have such a converter and use it routinely to print from my CoCo 2
to a HP DeskJet 540 printer.  The converter and CoCo are configured for 9600
baud communication...plenty for my uses.

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.

A printer driver would be a lot of overhead for a CoCo. The only way I'd
attempt something like that would be to write a print utility that would run
by itself. 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.

I thought pendrive and read and write anything you connect to usb I have the
protocol specification v1.0 and USB v2.0 and is communicated as 1st on the
low speed and then go up if You might still I also know that the protocol is
very difficult but the possibility of connecting any device through the port
(serial or cartridge) is interesting.
Could connect keyboards, speakers, Pendrives, printers
