The printer interface card furnished
with the Apple II computer
only passes seven bits to the LX-86, which means that you have a
7-bit system. Should you need an 8-bit system, the simplest solution
is to purchase a new printer interface card from your computer
dealer. Such a card is available for
the Apple II.
The Apple II uses CHR$(9) to “initialize” the printer. This code
and the following character or characters are intercepted by the prin-
ter interface card and used to change modes. You can divert all output
to the printer instead of to the screen by sending the following line to
the printer:
PR#1
PRINT CHR$(9)"80N"
Then type anything, followed by RETURN.
The CHRS(9)“80N” code directs all subsequent output to the
printer, up to 80 characters per row. You can cancel this by typing:
PRINT CHR$(9)"I"
or PR#O
The problem is that the LX-86 uses CHR$(9) to activate horizontal
tabulation and can also use it in graphics programs. When you send
this code, however, your system will interpret it as a printer initializa-
tion code and the program will not work properly. In these cases use
the following method to change your printer initialization code to a
number that is not used in the program. For example, you can change
your initialization code to one by typing:
PR#l
PRINT CHR$(9); CHR$(l)
IBM-PC solutions
There are two problems in using the IBM Personal Computer
BASIC to drive a printer. First, the IBM-PC BASIC inserts a
carriage-return/line-feed (CR-LF) after each
80
characters you send
it. Second, it adds an LF to each CR in an LPRINT statement.
Here is the way to adjust the width when it is the only problem.
Tell the computer that the print line is wider than 80 characters with
this WIDTH statement:
WIDTH "LPTl:", 255
F-7
