Hi, I posted a question recently asking how to print customer's name on our receipts especially for credit card transactions where the name is automatically printed on Customer's copy but not our own.
Some answers I received lead me to feel that I need to edit some XML files - but the actual answer is much simpler and I wanted to share it here.
All you need to do is go to Manager/Database/Registers/Receipt Formats. Choose the "40 Column Receipt Format" and choose to edit the "Sales" receipt. Then in one of the Footer Lines (near bottom) you can just enter "Customer.Name" and that's it. And now you will always be able to match the illegible signature of your customer to their name - and make it easier when credit card company calls and asks you to find the customer's receipt months later for some auditing purpose.
Good luck!
