Using the HP 82143A Printer
The HP
82l43A
Printer was designed specially for the HP-4lC calculator
system, adding powerful printing, plotting, graphics and special charac-
ter capability. When you plug the printer into one
of
the ports on the
HP-4IC, an impressi'
ve
set
of
printing functions becomes active.
This handbook takes you through the detailed operation
of
each
of
the
functions as well as the general operation
of
the printer. So that you can
become familiar with the capabilities
of
the calculator/printer system,
you should read through this handbook.

ALPHAs that are keyed in, function names as they are executed
from the keyboard, and output from print functions. Running
