I have an HP IR printer of the first model (A). It has worked flawlessly even though I bought it second hand. S/N is 272S10269.
Now there is one or maybe rows missing on the output on paper.
* indicates successful printing, - no printing.

Other data.
* No change with fresh/old batteries, neither when using charger.
* Version D as indicated last in the testpage.
* Prints as requested from all calculators that I have access to.I tried to see on Randys (fixthatcalc) page, but I found no help.
Anyone know how to solve it?
TIA Matti
