R — Rotate the picture 90 degrees in a clockwise direction.
Some printers require this option when printing the image double-
size. (See D above.)
An example of a graphics command would be CTRL-I GDIR2
followed with a carriage return. This will print the inverse of
HIRES page 2, double size, rotated 90 degrees. Options may be
listed in any order, as long as they are preceded by a CTRL-I G
and followed by a carriage return. Care should be used when using
the L” specifier. If too large of a left margin is used, the
picture may wrap around or, depending on the printer, it could
cause it to “crash” and then both the computer and printer would
have to be reset (see “D” option above).
Note: When typing Grappler commands directly from the keyboard
(not from a program), the Apple will give a syntax error. This is
normal since Applesoft doesn’t recognize this as a valid command.
To avoid this, type a one line program. For example:
10 PR#l: PRINT CHR$(9);"G”:PR
Then type RUN.
CHART RECORDER MODE
A chart recorder prints a continuous graph on a roll of paper.
If you need to chart more information than can be done on a single
HIRES screen, you can simulate a chart recorder by printing
successive screens without any intervening spaces. The type of
printer you are using will determine whether this can be done with
normal or rotated images. In general, if your printer prints six
graphics dots at a time (e.g. IDS Paper Tigers, Centronics 739,
Anadex 95ØØ-95Ø1), you will be using successive normal (horizontal)
screen dumps. If your printer prints seven dots at a time (e.g.
Epsons), you will be using successive rotated screen dumps.
