Printfil can print barcodes just by using some specialist Windows fonts, designed for that purpose.

In this video, we see some samples about how to use a Windows font for barcodes to obtain the bars printed on paper while the source program outputs just the textual code.

You can find all the files used in this demo, including the "Free 3 of 9 Extended" font (Code39) at https://www.printfil.com/eextra.htm, as well as other Windows fonts for different types of barcodes, like EAN13, I2of5, UPC-A, UPC-E etc.

Let's go:

Print a code from DOS Edit to LPT1:
Here it is, as normal
Now select a font for barcodes
Print from DOS again
This time you obtain a real barcode

For programmers:

Test1.prg: we've created a small dBase program that switches to that font before printing the code, then switches to the default font again
Everything is written in test1.txt
In Printfil, restore a normal font and columns = auto
Print test1.txt to LPT1:
Here is the mixed print job
In test2.prg print 40 spaces on top instead of 80
Print test2.txt to LPT1:
Width is doubled because the font fits a 40 columns page
Test3.prg enlarges the barcode and tighten the text via printer control codes
Test4.prg prints the code 3 times and lowers the text
