; NAME:
; PHASER
;
; PURPOSE:
; Issue the SET_PLOT and DEVICE commands appropriate for the Tektronix
; Phaser IIpxi color PostScript laser printer.
;
; CATEGORY:
; Device drivers.
;
; CALLING SEQUENCE:
; PHASER [, /LETTER] [, /LEGAL] [, /LANDSCAPE] [, /PORTRAIT]
;
; INPUTS:
; None.
;
; KEYWORD PARAMETERS:
; LETTER: If this keyword is set, output is produced for letter-sized
; paper. This setting is the default.
;
; LEGAL: If this keyword is set, output is produced for legal-sized
; papter. /LEGAL should be used for overhead transparencies as
; well, since these are legal size before the borders are
; removed.
;
; LANDSCAPE: If this keyword is set, output is produced in landscape
; orientation, i.e. with the X axis along the long edge of the
; page. This setting is the default.
;
; PORTRAIT: If this keyword is set, output is produced in portrait
; orientation, i.e. wih the X axis along the short edge of the
; paper.
;
; OUTPUTS:
; None.
;
; COMMON BLOCKS:
; None.
;
; SIDE EFFECTS:
; The plotting device is set to PostScript, 8 bits/pixel, color and with
; sizes, offsets and orientations appropriate to the keywords used.
;
; RESTRICTIONS:
; Because of the paper handling mechanism in the Phaser printer it is
; unable to print over the entire page. The actual print dimensions
; are 8.0" x 8.5" for /LETTER and 8.0" x 10.5" for /LEGAL.
;
; PROCEDURE:
; The SET_PLOT, 'PS' command is issued.
; Then PHASER issues a command like:
;
; DEVICE, BITS=8, /COLOR, XSIZE=SHORT_SIDE, YSIZE=LONG_SIDE, $
; XOFFSET = SMALL_OFFSET, YOFFSET = BIG_OFFSET, $
; /INCH, /PORTRAIT, [/LANDSCAPE or /PORTRAIT]
;
; The values of SHORT_SIDE, LONG_SIDE, SMALL_OFFSET, BIG_OFFSET are
; calculated for the paper size (/LETTER or /LEGAL) and orientation
; (/LANDSCAPE or /PORTRAIT).
;
; MODIFICATION HISTORY:
; Created 22-OCT-1991 by Mark Rivers.
