I have a program that is written in Realbasic and has been used from many years. It prints a barcode using a Datamax printer. The barcode font and size are hardcoded into the program. All computers using this program have the same fonts installed.

The same program on a Windows 7 computer does not print the correct barcode all computers with XP print correctly. I have talked to Datamax and spent a whole day trying to figure this out so far with no answer.

So far I have used the program on the Windows 7 computer to print to a HP2200 printer. The barcode printed is correct.
Printed the barcode to the Datamax 4308 printer connected to the Windows 7 computer. The barcode does not scan and visually is not the same as the one from the HP.
Printed a barcode using Notepad and the same barcode font. In 18pt. it does not work in 12pt. it can be scanned, not easily, and looks correct.

I also modified the program to allow the user to select font size. It did not matter if they choose 12 or 18pt the barcode printed was not scanable.

Has anyone seen this before or have any idea what to do?
