RS232 to Parallel Printer Converter

[Squibcakes]

Gave this example a try and can confirm that the code does work, however,

I woud recomend that Pin 18 not be tied to gound as some printers have a 5 volt supply on it.

For my application, I found that I needed to use the -BUSY signal so that all chars could be printed and increased the delay to 500... I used this code..

pauseus 500 'wait 200usec for printer to read in byte
high strobe 'clear the strobe
GOSUB READY



READY:
IF BUSY = 0 THEN RETURN
GOTO READY

Thanks again for the code....

Hi!!.
I was trying this code with an EPSON printer.
I am almost there but it seems nothing is being printed until the buffer of the printer is full. Is there any special character that needs to be send in order to execute the printing?

[Jerson]

if it is an inkjet printer, this is normal behaviour. To print what is in the buffer, send a Form Feed character (FF - ^L I think)

Although it was not an inkjet printer, this matrix printer executes printing after a line feed (10).

I was just trying to print dots for a plot

The code works great, very simple and nice

Thanks.
