It sounds like the font information isn't being embedded properly. I know a lot of the MT fonts will not embed (a licensing issue with MS). Go to File>Properties>Fonts. Does it list ArialMT and does it say embedded or embedded subset next to it?
ah ha, I just found the common denominator..
All the lines of text that won't display have a diameter ø symbol in them.
Apparently that doesn't want to cooperate?
Fantastic. I had the same problem Same error in Properties, in my case it was the degree symbol in a dimension on one layout.
I turned the dimension to text and exchanged the original Arial symbol for a Times New Roman one and it work.
I also made sure that all fonts were embedded out of AutoCAD 2011 (dwg to pdf.pc3 > Custom Properties > Capture some > Edit Font list > Check All)
Pdf works perfectly now.
The problem lies with AutoCAD, TrueFonts, special symbols, and the AutoCAD Native PDF driver 2008+. Open the print driver go to Custom Properties. Set Font Handling to Capture all.
I am also having same issue , I am generating a pdf file from my application and once it opens I try to print it , as soon as I try to print , it would give me an error 'cannot find or create the font wingdings 2'. some characters may not display or print correctly . When I get past this pop up , I can still print the document and I can print as many times I want without error but for the first time it throws an error.
I've also tried to turn of the local font setting in acrobat reader to see if that helps and waiting for the user to come back with an answer.
Please provide your valuable suggestion .
Thank you in advance.
