There are a number of things you can do to customize and manipulate the receipts being printed from your register. For information on emailed receipts, check out our archive of newsletters.
At the top of the receipt, your company information will print. This is set through tools -> options, under the company info tab, and consists of four lines. By far, the most common setup is as follows:
Company Name
Address
City, State, Zip
Phone and Email
That said, you can customize this to some degree; the only required field is the company name, which also appears on labels.
Also at the top of the receipt, if your receipt printer supports it and you have chosen to load one, is the logo. We are able to help load logos for supported customers who get the printer through us - all of the models we sell these days support them - but you will need to provide the logo in a graphic format. It's important to have a logo that will look good in black and white - green on red, for instance, will just come out as a blob.
At the bottom of the receipt are a few options - general invoice notes are printed on each and every receipt, no matter the printer. These consist of up to ten lines of whatever you want, and can be set through view -> general invoice notes from the main invoice screen. The most common things this is used for include return policies as well as upcoming events and specials.
Also at the bottom of each receipt, on certain configurations, is the 'couponing' information set through the tools -> options screen. This does not have to be a coupon, but it will appear within a black box in relatively large font, with each line getting progressively smaller. This is only available on a small subset of printers, but you can try and see if it works for you.
Finally, you can place invoice notes on a particular invoice; similar to general invoice notes, these appear at the bottom of the receipt, but these are for a particular invoice and can be used to mark information about the transaction that the customer should know or that you need to know for returns of the item - for instance, that the particular items are 'as is'. You get up to five lines of these per invoice, and may set them after at least one item is on the invoice by going to the invoice menu on the screen -> invoice notes.
