Printing
The calculator can print information using the HP 82240A Infrared
Printet, which
accepts
the infrared signal
generated
by
the printer
port. This
chapter describes the types
of
information you can print.
Operation
of
the printer is covered
in
the printer owner's
manual.*
Theprintannunciator(h)comesonwheneverthecalculator

The lnfrared Printer Port
Because
conununication
goes
only
one
way (from the
calculator
to the
printer), the calculator cannot determine whether the printer is receiv-
itg
information.
To preserve
battery power, the HP-275
will
not
transmit data
to
the
printer when the low batteries annunciator
({=)
is on.
If
low
bat-
tery power occurs after you've started printing, printing stops and the
calculator displays BHTT

PRINT.
* Since
the HP-275
cannot send control
characters
to
the
printer,
portions
of
the
printer's
manual pertaining
to
control
codes
and graphics
characters
do not
apply.
