RE: Bar Code printing example

While AFP would make this easy, I doubt that the Okidata or Epson support it.

I'd guess both just support ASCII. Do you know for sure that either one supports a ASCII command
sequence to print a barcode?

The problem you're going to hit is that your RPG program outputs EBCDIC; while the printers understand
ASCII. For basic stuff, the Host-print-transform (HPT) built into OS/400 handles the EBCDIC to ASCII
conversion just fine.

The special command sequence to print a barcode will be a problem.

However, there is a way to get HPT to ignore certain strings in your spool file so that they get sent
to the printer directly. This string would be the ASCII binary values you need to tell the printer to
print the barcode. This functionality is called transparency. You'll need to look around online to
see how to do it.

Another option, would be to have your RPG program write an ASCII file directly. I think you'd need to
write to the IFS and them use something else to send the data to the printer. There's someone on this
list that's done that with postscript files, so hopefully they will jump in or you might look in the
archives.

HTH,
Charles

Sheri, You want to read about Advanced Function Printing.
Your shop does not use any package like T.L Ashford?

Hi Group,

I am a novice RPG programmer and my boss as asked me to
modify our 'picking slip' program to include a bar code
(order and order generation #). We currently print on an
OKIDATA Microline 590 line printer and want to move to an
Epson POS printer, model TM T811V. Additionally, we would
like the printer to cut the paper after printing each pick slip.

I have no experience printing bar codes and don't know where to start.
The existing program was written in 1992 (yikes) in RPG.

If anyone has a sample program, or can point me to a sample
on the web I would really appreciate it.

Thanks.

Sheri
