  HP Printer Paper Selection? 
 The Question is:
 
How can I print an A3 format with an hp post printer ?
I print A4 format.
 
thank you
 
 The Answer is:
 
  No clue.  Please ask HP how the printer paper selection works.
 
  You will then end up figuring out how to use the particular
  printing software (DCPS, LPR/LPD, Telnet, etc) to communicate
  this request over to the printer, and/or to establish a queue with
  this attribute by default, and/or how to use the available printer
  forms mechanism.
