Possible to port a P.O.S. to FPC/JVM?

[ozznixon]

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][+][-]

1. var
2.   print: AZCBlueToothPrint;
3. begin
4.    print:= AZCBlueToothPrint.Create(Self);
5.    print.OpenDevice;
6.  
7.   if not print.write(JLString(' Kupac: ')) then begin end;
8.  
9. 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!
