Nothing showed for Printer Features trying to print from Preview app.  I also tried BBEdit (a great text editor) and it crashed as soon as I opened the Printer Features menu.  I was able to grab the Console log, the System log, and the crash report from BBEdit later today.

So that suggests that the problem isn't with paper sizes (or that there's another problem).  Next
step is around line 1222 in genppd.c:

  int maximum_level = simplified ?
    STP_PARAMETER_LEVEL_BASIC : STP_PARAMETER_LEVEL_ADVANCED4;

Please change STP_PARAMETER_LEVEL_BASIC first to STP_PARAMETER_LEVEL_ADVANCED4 then 3, 2, and 1 to
see when (and if) things start working again.
