A PDF 1.2 file produced from TeX using embedded fonts and gs 8.11 under Linux on an x86 machine displays correctly with all versions of Acrobat, but prints correctly only with Acrobat 4 or later. Interestingly, the same PS file run through gs 8.00 on another machine (Sun Ultra 5 running Solaris 8) does not have this problem. One obvious difference: this latter PDF file renames the TeX fonts, such as CMR10, to names such as Fa. The URL above contains the original PS file, both PDF files, and the result of running the gs 8.11 PDF file through different versions of Acrobat. I have labeled this bug as minor, both because Acrobat 3 is obsolete and because the different behavior on different installations suggests a configuration problem. Nonetheless, I am hesitant to post such PDF files online without being sure the fonts are embedded correctly.
The bug 687047 may be related to this problem.
I should have added that gs 8.00 produces the same (buggy) behavior on the Linux machine; this is not (just) an 8.00 vs. 8.11 problem.
We've observed a lot of problems in the past with Acrobat 3.
This may indeed be an Acrobat3 problem, but it still worries me that a single PS file converted to PDF using gs 8 on two different machines produces one PDF 1.2 file which works with Acrobat 3 and one PDF 1.2 file which is buggy with Acrobat3.
