Are you using Postscript fonts? Don't use them anymore. Other problems I have not seen.
Yes, but we have no choice but to use Postscript fonts with client’s files. And clients don’t understand why there is a font problem. (also use Extensis Universal Type)
When you use InDesign or other Adobe Applications you can put your postscript fonts in the folder aside the program. Then these font can be used still now.
But PostScript Fonts should be replaced by modern OTF font. It is not Adobe which is not supporting T1 fonts, it is Yosemite and Windows 8.1 have abandoned the T1 support.
It is your task to educate your clients. Fonts are programs like other programs too. And no one would expect that any modern OS would support programs from the 1990s, that is the same with fonts. Since the early 2000 all fonts have been sold as OTF too. A problem is that still up to today many users buy T1 fonts as they have no clue what is going on.
I can only recommend to you, stop using postscript: no T1 fonts, no EPS and no printed PDFs.
