Can my logo and my opening hours print on the receipt?

Yes. Under Settings → Printing & receipts, What the receipt says, tick Print your logo at the top, which prints it in black and white, centred, at most two thirds of the roll wide, and Print your opening hours, which takes the hours from your restaurant details. The classic style also takes A line under your name, and the kitchen ticket has its own tick for the customer's name, phone, building and payment. The preview beside the form shows the logo exactly as it is sent to the printer. The POS and the counter tab in the docs covers the receipt's wording.
