For each model, you'd need about 64 bits to represent the supported command
list and likely future expansions, and another 64 should suffice for maximum
allowed paper size.  You can fit descriptions for 64 different models
in just a kilobyte.

  if (printer_commands[model]&SOME_COMMAND)
     command is supported
  else
     not

Roughly speaking, of course.
