The printer powers on with the Roman 8 character selected for compatibility
with other calculators. Since the HP48 does not know what mode the printer
is in, it frequently sends the escape code to select the ISO Latin-1
character set when printing. As Jim noted, for the version B printer the
characters inserted in PRTPAR by executing OLDPRT must be deleted so that
the HP48 does not remap the characters for the version A printer.
