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.
