Challenge with users able to change Specification

Dear Team,

Funniest thing, all working fine then suddenly a call receipts in Bank Recon printing weird.

Upon checking the fix was simple, they were using the wrong specification, instead of that which was being used for 2-3 years now???

How do I SET the correct specification and only admin can change.

Is that possible?

Thanks
Edward

Hi Edward:
How many Receipts do they use? If just one, why not remove all of the others?
