hp 11c
#1

got this in london in 1983
still going strong
but my hp 720c printer heads wont align..just 2 1/2 years old
any advice to an old pro.

#2

Whats the point? I do not see the connection between a non mechanical calculator and a very mechanical printer and surely not all 11C calculators were functioning 2 1/2 years after purchase for whatever reason.....

#3

thought someone would suggest what i should do with the 720c to clear the fault. or what might be causing it. thanks for your reply.
