I still have one of these computers also...and a printer. I collected every book I could find for the programs. Mine had a problem with the power connector, it would suddenly come out, usually when I was in the middle of typing a program.
I used to have this combo, and I had no problems with it, unlike you.
I also had a brilliant "banner" program that would print huge letters on the thermal paper, and which could then be stuck on the wall as a... well, banner.
And I used to love the thermal smell of the paper once it had been printed, too.
Well actually the ZX81 didn't have a graphics chip at all, just a little bit of glue logic which needed lots of assistance from the CPU. The CPU virtually had to do everything itself. (If I'm not mistaken it had to "execute" a certain memory location which was then replaced by NOPs, but the hardware loaded ROM values into a shift register or something.)
Ah, the memories and the fun of writing huge programs and printing them out, I can still smell the burning now :) I used to find it was better if you hung a clothes peg off the paper at the back. to help 'drag' it down.
Oh how i remember the quiet-as-a-whisper printer :)

Haven't tried it since about '83.

'cool, though..' and the paper falls off the table that instant. :))
anyway, i have a spectrum +, which, i think, is mostly the same internally, but your zx81 looks tiny in comparison..

Wow I only had the ZX80 with the ZX81 rom and no printer. Neither did I have a tape recorder that would work with it.

Great machines. I still have two of them.

But why o why did it NOT use ASCII?

A friend of mine printed out his homework on C64 printer which was kind of like this. From what I remember the teacher threw the thing into the bin.
