The following table describes the supported printer functions.

   Just Because We Have It Doesn't Mean You Do.
   --------------------------------------------
   Not all printers support every command.  Unsupported commands will
   either be ignored or simulated using available functions.

To transmit a command to the printer device, you can either formulate a
character stream containing the material shown in the "Escape Sequence"
column of the table below or send an prd_prtcommand device i/o command
to the printer device with the "Name" of the function you wish to
perform.

   Legend:
   ------
   ISO     indicates that the sequence has been defined by the
           International Standards Organization.  This is
           also very similar to ANSI x3.64.

   DEC     indicates a control sequence defined by Digital Equipment
           Corporation.

   +++     indicates a sequence unique to Amiga.

   n       stands for a decimal number expressed as a set of ASCII
           digits. In the aRAW string ESC[5"rHELLO, n is substituted by 5,
           the number of RAW characters you send to the printer.
