Scenario：

If the PrintType is selected as “Print by merchant” for paper tickets, after the ticket issuance is completed, the POS system must call the “Get Paper Ticket Information(QueryPrintData) API” to obtain the ticket information. Then, the merchant can print the ticket with a printer and hand it over to the customer. If the “Print by ECPay” option is selected, the tickets will be printed by ECPay and delivered by a dedicated person.
