I've managed to finally almost crack the two printers problem but I'm have a small problem that's breaking my brain.

top line are the answers and bottom line are my results. As you can see apart from 3 results I'm spot on.

the three lots of data I'm getting wrong are

13517793 7850424 29 -

68797884 8616115 8 -

170203 173461 5693

Can someone please help before I go completely insane?

Thanks Quandray - I managed to crack it using the difference in differences between value and mod to ascertain which printer would be printing the final sheet.
