N.Y. Comp. Codes R. & Regs. tit. 9, § 5319.26 – Printers.

(a) A gaming device shall have a printer that is used to make payments by issuing a printed voucher. Such printer shall print on a voucher as set forth in section 5319.28 of this Part. A gaming device shall support the transmission of data to the gaming facility accounting system that records the following information in regard to each payout voucher printed:
1. (1) value of credits in currency;
2. (2) time of day the voucher was printed in 24-hour format, showing hours and minutes;
3. (3) date indicating the day, month and year;
4. (4) gaming device number or machine number; and
5. (5) unique validation number.
(b) A gaming device shall either keep a duplicate copy or print one copy for the player, but shall have the ability to retain and display the last-25-voucher-out information to resolve player disputes. In addition, an approved system shall be used to validate the payout voucher, and the voucher information on the gaming facility accounting system shall be retained at least as long as the voucher is valid at that location. If offline voucher issuance is supported, a gaming machine shall mask all but the last four digits of the validation number as displayed in the 25-voucher-out log.
(c) The printer shall be located in a locked area of a gaming device (i.e., require opening of a locked external door), but not be housed within the logic area or the drop box.
(d) A printer shall have mechanisms to allow control-program software to interpret and act upon the following conditions:
1. (1) out of paper/paper low. It is permissible for the gaming device to not lock up for these conditions, yet there shall be a means for an attendant to be alerted;
2. (2) printer jam/failure; and
3. (3) printer disconnected. It is permissible for the gaming device to detect this error condition when the game tries to print.
