You should be able to get information on the timing requirements and
data encoding of the IR transmission method used for the HP IR printer
by contacting HP's Calculator Support. Their number and address is
listed on the inside back cover of the printer's (or any HP calculator)
owner's manual. The information can also be found in the October 1987
issue of the Hewlett-Packard Journal.
