PLOTDUMP (Version 5.3) Instructions
The command PLOTDUMP installs the PLOTDUMP Terminate & Stay Resident
program in memory; the PLOTDUMP TSR will dump a graphics image to a
printer when the keys Ctrl-PrtSc or Ctrl-Shift-P are pressed. The
PLOTDUMP command can optionally be followed by a space and then one
or more of the following switches:
/r Rotates the image 90 degrees.
-r Resets rotation.
NOTE: Rotation can be toggled with the hot keys Ctrl-Shift-R.
/a Selects Alt-Shift-P as the keys for dumping an image and
Alt-Shift-R for rotating the image.
-s Disables use of the Shift hot keys.
/pe Selects 9-pin Epson LX-800 compatible printer (the default).
/pp Selects 24-pin Epson LQ-850 compatible printer.
/po Selects 9-pin Epson printer graphics mode used with older versions
of PLOTDUMP which produced a narrower vertical plot.
/pi Selects 9-pin IBM proprinter compatible printer.
/ph Selects HP LaserJet compatible printer.
@n Selects printer port LPTn where "n" is 1, 2, 3 or 4
(default is LPT1).
The PLOTDUMP program can dump 720x348 Hercules and 640x200 (mode 6) CGA
monochrome graphics images and 640x350 (mode 16) EGA and 640x480 (mode
18) VGA color graphics images inwhich all foreground colored objects are
displayed against a single background color. By default, with an EGA or
VGA image, the background color (color index 0) is printed as white and
all other colors are printed as black. The following switches affect how
colors are printed:
/v Reverses printed image (only the background is printed as black).
-v Resets reverse print.
/cn Selects color index "n" (0 to 15) as the background color
(default is /c0).
The PLOTDUMP command will display the current settings if it is given
after PLOTDUMP has already been installed as a TSR; the following
switches can be used to change settings after installation: /r, -r, /pe,
/pp, /po /pi, /ph, @1 to @4, /v, -v and /c0 to /c15. All other switches
only have an affect when PLOTDUMP is installed as a TSR.
The PLOTDUMP command installs the PLOTDUMP program as a Terminate & Stay
Resident program in memory. If plot dumps are made often then the
PLOTDUMP command should be placed in the AUTOEXEC.BAT file (the file
PLOTDUMP.COM must be in the root directory or a path must be specified
to the directory containing the file).
NOTE: In order to dump to a printer a plot drawn by the SPLOT (Screen
Plot) program, the PLOTDUMP program must be installed in memory before
making the plot.
NOTE: Pressing the ESC key will abort output to the printer.
Technical note: Besides pressing Ctrl-PrtSc or Ctrl-Shift-P, a graphics
dump can also be invoked by calling software interrupt #60h. Besides
the interrupt #60h vector, the routine also uses the interrupt #61h
vector to store the string "WGH" as a flag that the routine has been
installed. Installation switch #n select an alternate software interrupt
number: 60 ≤ n ≤ 65; i.e. #65 selects #65h for calling and #66h for
the flag. Switch #0 disables use of a software interrupt and switch
#72 selects the software interrupt used by previous versions of
PLOTDUMP; switch #72 should NOT be used unless compatibility with
a previous version is required since vector #72h could be used with a
hardware interrupt on AT and 386 class PCs.
