Hi, Dennis -
I can only make some guesses, since I do not have the font that you are using. I'm a little confused by your labeling of the second image as "Using pdfdocument"... Is this how the PDF created by the DataWindow appears when viewed in a PDF viewer, such as Adobe Acrobat? One guess is the viewer utility you are using cannot handle this font.
The issue may be due to the font or to the utility that is rendering the PDF. Have you tried any alternative Code 3 of 9 barcode fonts?
I threw together a quick test using the "Libre Barcode 39 Text" TrueType font that is distributed by Google:
https://fonts.google.com/specimen/Libre+Barcode+39+Text
The barcode was created in a DataWindow using this Libre font, then A PDF file was saved from the DataWindow using PB 2022 R3, then opened in Acrobat:
I also tested with another Code 3 of 9 font (called "Code 3 de 9") that is closer in appearance to the one you are currently using. It was downloaded from the URL below:
https://grandzebu.net/informatique/codbar-en/code39.htm
Once the PDF file was created, I un-installed this font, then opened the PDF file in Acrobat:
So it does appear that the barcode font is included in the PDF created by PB.
I hope this gives you new avenues to pursue.
Best regards, John
