I try to make an EAN-13 barcode with Barcode wizard. Barcode itself is fine but instead of numbers under the barcode there is only square boxes. It seems that the default barcode font OCR-B 10 BT works not at all with my Corel. The same truetype font works fine with MS-Word and Adobe Pagemaker in the same computer!? The font option in barcode wizard is greyed so I can not change the font so I can not make working barcodes at all. I have reinstalled the font with no help. How can I get my Corel to communicate with this font? My colleagues do not have any problems with the font.
The barcode wizard is working as designed.
What you'll need to do is copy the barcode, and paste as special.
Edit > Paste Special.
Now you can ungroup it and change the fonts.
