Final answer:
The ability to print a duplicate receipt depends on a business' policies and practices, and while it's often possible for customer service or records, it may be restricted in certain cases.
Step-by-step explanation:
The question regarding the allowance of printing a duplicate receipt seems to deal with a business or commercial policy rather than an academic subject. Typically, businesses will have a policy about whether or not duplicates of receipts can be printed. The answer to this can vary depending on the business' practices and the point of sale systems they employ. In some cases, it's entirely possible to print a duplicate receipt for record-keeping or customer service needs. Therefore, the statement 'You are not allowed to print a duplicate receipt' can be false; however, this could be true in specific contexts where a business has a strict policy against printing duplicates for security or fraud prevention reasons. To properly answer the question, additional context would be needed about the policies of the particular business or establishment in question.
