Oops, this time with the proper tag


I'm going to be building a device that translates printer output from a Meiki
injection molding machine which uses a special NEC printer (expensive wide dot
matrix for which I cannot find a manual) to a RS232 pc connection or a more
standard printer.

The output I get on a standard printer is pretty close to what I need there are
just a few characters that need to be replaced by others.

The plan is to use a 16f877 with it's PSP connected to the printer connection
collect characters use lookup table(s) then send out the modified stream back
out thru RS232 or parallel thru some other I/O pins

The amount of data is not that great ( screen of about 40*25 chars ) and as far
as I can tell there are no graphic characters are sent.

Are there any gotcha's you can think of , any hints or perhaps even a completely
different way to do the same simpler.

Changing the machine is not an option, I have to have a portable solution to
print out data from a hundred or so machines.


Any help would be appreciated.
