Help! Errors in printing.. jumbled fonts.. also print to PDF export, then printing the PDF results to same problem. recently installed Mavericks..

Have been having lots of trouble with Mavericks since installation.

Aside from 2 out of 3 printers not responding to print, now if you print a Numbers doc to PDF and print the exported PDF. The resulting print out is jumbled letters and fonts.

I hope this gets resolved by the Mac OS team. These errors are critical if you depend on Macs everyday.
