You must embed the escape sequences with the 4GL statements. Here's an exaple where I print the barcode for 5 data elements using an HPL laserjet printer. THis is old code, so I don't remember the model number.

The point is you'll have to check your printer documentation:

LET prt_cmd_str =
    ASCII 27,"(0Y",               # Select barcode font
    ASCII 27,"(s0p8.1h12v0s0b0T", # Pitch set.
    ASCII 27, "&a9R",             # Line 9.2
    ASCII 27,"&a6C",              # Column 6
    "*",r_itmrcpt.receiptid CLIPPED,"*",
    ASCII 27, "&a12R",            # Line 12.2
    ASCII 27,"&a6C",              # Column 6
    "*",r_itmrcpt.pallet CLIPPED,"*",
    ASCII 27, "&a15R",            # Line 15.2
    ASCII 27,"&a6C",              # Column 6
    "*",r_itmrcpt.mm CLIPPED,"*",
    ASCII 27, "&a18R",            # Line 18.2
    ASCII 27,"&a6C",              # Column 6
    "*",r_itmrcpt.item CLIPPED,"*",
    ASCII 27, "&a21R",            # Line 21.2
    ASCII 27,"&a6C",              # Column 6
    "*",dispqty USING "&&&&&&","*",
    ASCII 27,"(0U",               # Ascii
    ASCII 27, "&a24R",            # Line 24
    ASCII 27,"(s0p10h6v0s0b3T"
 
  PRINT prt_cmd_str CLIPPED

I'm sorry, but I don't have access to an HP 1300. The documentation should describe the escape codes required.

Also, not every laser supports barcodes. Are you sure that yours does?

Sorry I can't be more help.

Another way to print barcodes is explained there:

http://www.iiug.org/software/index_I4GL.html

Some resources are related to printing barcodes. The principle if far different than what is explained by 'olded'. It's in fact printing small black boxes.

We use Hp printers and this works.
