Hey guys,

I was asked to port my Point of Sale software to droid for a customer. Before I run and trip, I figured I would ask is it possible to do the following via FPC/JVM?

(using DOS terms):
Open LPT1 and print 80 chrs or less per line?
Send ^G (#7) to LPT1 during print to open cash drawer?
Interface with Credit Card reader from the headphone jack, like Square does?
Interface with a USB Bar Code Reader, and
Interface with a USB rewards card reader/Credit Card - if not using the headphone jack concept

Print to Android with BlueTooth

Pandroid unit:
https://github.com/zeljkoc/pandroid/tree/master/units/AZCBlueTooth.pas

example:

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---var print: AZCBlueToothPrint; begin print:= AZCBlueToothPrint.Create(Self); print.OpenDevice; if not print.write(JLString(' Kupac: ')) then begin end; end;

Thank you! So that gets Printing out of the way, now I just have to read from card readers and bar code scanners - and I will be ready to start the port!

Thanks!
