Qualifiers

/OUTPUT
      /OUTPUT[=filespec]
      /NOOUTPUT

   Controls where the output of the command is sent. By default,
   the output of the SHOW PRINTER command is sent to the current
   SYS$OUTPUT device (usually your terminal). To send the output
   to a file, use the /OUTPUT qualifier followed by a file
   specification.

   The asterisk (*)  and the percent sign (%) wildcard characters
   are not allowed in the file specification. If you enter a partial
   file specification (for example, specifying only a directory),
   SHOW is the default file name and .LIS is the default file type.

   If you enter the /NOOUTPUT qualifier, output is suppressed.


/IDSTRING
   Returns the USB printer ID string as a text string and displays
   it on your screen. This information appears at the end of the
   typical SHOW PRINTER command display.


/SERIALNUM
   Returns the USB printer serial number as a text string and
   displays to the screen. The USB printer returns the serial number
   in Unicode format, and this is converted to ASCII text before
   being displayed.
