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  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i 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!
