Apple Grr - Manual (Page 3)

CTRL-lnP
CTRL-lnL Sei left margin to nth column. All
subsequent printing will have n spaces a1
the start of each line. For example, w'hen
using CTRL-1 10L, all printing will start in
the 10th column.
CTRL-lnR Set right margin to nth column from left
edge of page (not left margin). This
command will prevent words from being
split at the right margin. The Grappler will
end the line at the first space that occurs
after the right margin, but before the end
of the line as set by the CTRL-InN
command. A right margin of zero
disables this feature.
Set page length to n. The printer will print
six linefeeds after n number of lines have
been printed. A page length of zero
disables the page length feature.
Continuous form paper typically has a
total of 66 possible lines per page (this
may vary with the type of printer).
Therefore if you specify a printed page
length of 60 lines (CTRL-I 60P), your printer
will print 60 lines and automatically skip
over the perforation with 6 line feeds.
Turn on bell. This allows a CTRL-G to ring
the printer bell. Many printers do not
have a bell so check your printer manual
to see if this feature is available.
Turn off bell.
Duplicate the present text screen on the
printer. The screen will be printed
20 spaces from the left edge of the ;
paper. This command is accessible from
BASIC only as it uses some of the monitor
routines. Only the forty character screen
is printed. Eighty character boards are
not supported.
CTRL-l CTRL-Y Change to new command character
CTRL-Y. To do this, type in CTRL-l CTRL-Y.
Any control character may be used here
(instead of CTRL-Y) but you should avoid
characters used by your printer or normal
text control characters such as CTRL-M
(carriage return).
CTRL-l B
CTRL-l C
CTRL-l S
CTRL-Y CTRL-l Changes back to command character
CTRL-l.

GRAPHICS FEATURES AND COMMANDS
The Grappler interface can output the HIRES screen to
the printer by using simple commands. All graphics
commands consist of the command ctiaracter (usually
CTRL-l) followed by a "G," and any options described
below. If no other options are used (i.e. CTRL-l G
[carriage return]), HIRES page 1 will be printed
horizontally with every white dot on the screen printed as
a black dot on the paper. The different options are
described as follows:
2 — Print HIRES page 2 instead of page 1.
D — Print the graphics screen double size. Some
printers don't have enough character positions to print a
double size image horizontally (e.g. MX-70, MX-80,
IDS-445). If that is the case, you must also use the "R"
option. Otherwise your printer will get confused and
"crash," meaning it won't do anything. If that happens
you will have to reset the APPLE by pressing the reset
key, and then reset the printer by turning it oft and then
on again.
E — Prints an "emphasized" image (EPSON MX-80,
MX-80FT, MX-100, MALIBU 20'0oniy), When in this mode,
the printer will print two closely spaced dots for every
one it would normally print. This results in a denser
image but printing time is twice as long.
I — Invert the image before printing. Normally, every
white dot on the screen is printed as a black dot on the
paper. This works fine for lines and graphs but if you are
printing an actual picture ot a person or object it will
