No. This would undermine the effort to produce a speedy checkout. Print all invoices, possibly in multiple stacks, (complete each print run separately though so that one stack is ready before printing additional stacks) prior to checkout so that cashiers need only to thumb through the stack to produce the invoice. Or, print by table number and deliver invoices to tables while guests are still seated. If the auction has a high number of invoices that only have Other Bid purchases and no auction items, consider printing only invoices with auction items first, as they are the most important ones for the checkout process.
