The alternate control sequences (Epson-like) are activated differently
in different ThinkJets, depending on the interface:
* in the RS232 version it is a dip switch (number 5 to be exact - yes, 
  I have the manual open in front of me);
* the HP-IL version has no dips but the alternate mode can be selected
  with HP-IL commands (DDL 6, DATA 18);
* the parallel (Centronics) version I think uses dips too, but I don't 
  have the manual at hand;
* the HP-IB version I've never used, but think it might use software
  commands like the HP-IL version (although it is possible it really doesn't
  have alternate mode).
