Orange Micro Interface The Grappler - Manual (Page 4)

To type a control character, hold down the control key
(marked “CTRL’ on the Apple) and then press the appropriate
letter. Then release the letter key, and then the control key.
Control characters do not appear on the screen as they are
typed. You may also use the CHR$ function found in Applesoft
Basic (consult your Apple manual and Appendix A).
TEXT COMMANDS
Spaces have only been used to make the commands easier to
read: do not type the spaces when issuing the command.
PR#n Turns on the Grappler interface card. n is equal to
the slot number of the Grappler. All subsequent
characters appearing on the Apple video screen will
also be printed on the printer. This command must be
used before any of the following commands will be
accepted by the Grappler.
PR#Ø Turns off the Grappler.
CTRL-I A Append line feeds onto carriage returns. Basic will
not send a linefeed after a carriage return. This
means the printhead will return to the left margin but
will not advance the paper. The Grappler will auto-
matically issue a linefeed command and advance the
paper after every carriage return. If your printer is
performing double line spacing, check Appendix B of
this manual.
CTRL-I K Don’t append linefeeds onto carriage returns.
CTRL-I H Allows the high order (8th) bit to be output to the
printer. On many printers this has no effect. On
some it allows printing of block graphics (Epson MX/8Ø).
However, when block graphics are being printed, the
standard character set is not accessible.
