Where did you see the printer’s information in the First Edition? I couldn't find it.
On the last page (page 212) at the bottom.
Page 212 of ZX81 manual (first edition)

Interesting!

None of my four have that printed on page 212.

I assume there must have been at least two print runs of this edition then.
