/* Sony UP-DR150/UP-DR200 Spool file format

   The spool file is a series of 4-byte commands, followed by optional
   arguments.  The purpose of the commands is unknown, but they presumably
   instruct the driver to perform certain things.

   If you treat these 4 bytes as a 32-bit little-endian number, if the
   most significant four bits are bits are non-zero, the value is is to
   be interpreted as a driver command.  If the most significant bits are
   zero, the value signifies that the following N bytes of data should be
   sent to the printer as-is.

   Known driver "commands":

   6a ff ff ff
   fc ff ff ff
   fb ff ff ff
   f4 ff ff ff
   ed ff ff ff
   f9 ff ff ff
   f8 ff ff ff
   ec ff ff ff
   eb ff ff ff
   fa ff ff ff
   f3 ff ff ff
   ef ff ff ff  XX 00 00 00   # XX == print size (0x01/0x02/0x03/0x04)
   f5 ff ff ff  YY 00 00 00   # YY == ??? (seen 0x01)

   All printer commands start with 0x1b, and are at least 7 bytes long.

  ************************************************************************

  The data stream sent to the printer consists of all the commands in the
  spool file, plus a couple other ones that generate responses.  It is
  unknown if those additional commands are necessary.  This is a typical
  sequence:

[[ Sniff start of a UP-DR150 ]]

<- 1b 16 00 00 00 00 00
-> "reset" ??

[[ begin job ]]
