There's a guy in Newcastle who has an exclusive franchise deal for the
actual printing, but I think he sub-contracts the distribution.

Who cares who prints them? What matters is that they only get printed
when your program is broken. So instead of trying to track down the
error messages, track down their causes. Typically, these include
incorrect memory management (e.g. freeing something you didn't malloc),
array bounds violations, and related pointer problems.
