If someone had a business, a receipt printer would be a great thing to have. Customers like receipts, and it’s nice to have a printed receipt to give them.  I went to a huge consignment sale last fall that had baby clothes and anything related to babies and toddlers.  They had a receipt printer there this last time, and it made things run so much smoother than the previous time.  It was a great help to all the people working there!
