while keying this post in, James was faster and posted about the self test, too. I'll keep mine the same, just add these lines, O.K.? (Hi, James!)
chances are you have a bad connection. in the flex ribbon connecting the printing head to the mainboard. The October 1987 issue of the HP Journal, p.22, shows an HP82240A 'guts', and you can easily see the flex ribbon.
If you want to go for another test, what do you get with the HP82240B self test? If you did not perform it so far, simply keep the paper advance buttom pressed when turning the printer on. The complete character set and the battery condition are printed (battery condition is printed in a separated line).
Also, does it happen the same when printing graphics? I mean, with both the HP48GX and the printer ligned up for printing, if you press [ON] (hold it) and  simultaneously (release  prior to release [ON]) while the HP48GX is turned on, what do you get in the printer?
Maybe you are aware of that, but the [ON]& cause the HP48G's LCD contents to be sent through the selected IO port. Considering that the IR port is the selected one (as you can print with the HP82240B), your printer should print the exact LCD contents when [ON]& are pressed.
Let us know how does it go, or if you need further advice, O.K.?
