Hello!
I am using Spire.PDF free version.
When i tried to print some PDF files they was printed without text. I found that this problem (#1) was due to the "arial" font installed in the operating system. When i installed new "arial" font that issue dissapeared for new files. But old files still not printing.
So i tryed to replace font in old files before printing. But now i have a new problem (#2): UsedFonts property does not works.
In the attachment you can see a test pdf file with error, that couses the problem #2 and "arial" font, that couses the problem #1.
Can you help me to solve this issues?
