Item 2-1 shows a combination of receipt and journal printing. Item 2-2 shows processing to issue a Taiwan receipt. Tips include features of stamp printing and usage of the ESC o command. Note: Print samples are images of the printing results of the program samples. They do not represent the actual printing.

CONFIDENTIAL ■ ■■ ■■ ■ more Tips RP-U420 has a stamp function. ESC o executes a stamp once. When printing a stamp, you need to set line spacing, depending on the position of each mechanism.
CONFIDENTIAL However, if you do the procedures above at the beginning of a receipt issue transaction, there will be space of about 14 lines above the stamp. As the program examples in this section show, if printing of a stamp for the second receipt is executed during the receipt printing for the first receipt, you can print a receipt without unnecessary spaces. If you use the autocutter, follow the steps below. 1.
CONFIDENTIAL ■ ■■ ■■ ■ more Definitions DEFINITIONS (1) Normal commands Normal commands are all the commands except real-time commands. The normal commands are stored in the receive buffer temporarily and then processed sequentially. (2) Real-time commands Real-time commands are the commands that consist of a DLE extension (such as DLE EOT or DLE ENQ). The realtime commands execute processing when received.
CONFIDENTIAL (11) Horizontal/vertical direction Horizontal direction is the direction which is perpendicular to the paper feed direction. Vertical direction is the paper feed direction.

CONFIDENTIAL Using the character code tables USING THE CHARACTER CODE TABLES The example below uses Page 0 (PC437) to illustrate the use of the character code tables. You can find the character "A" in Page 0 as follows: The decimal value for the character "A" is 65. Follow its column straight up to find the digits. Hexadecimal 4 Binary 0100 These numbers are the most significant bits of the ASCII code. Follow its row to the left to find the digits.

CONFIDENTIAL ■ With a serial interface model, this command is executed even when the printer is offline, the receive buffer is full, or there is an error status. ■ With a parallel interface model, the printer cannot receive data when it is busy; therefore this command cannot be used under the following conditions. • • When DIP Switch 1-6 is On: receive buffer-full. When DIP Switch 1-6 is Off: receive buffer-full, offline, error status.
CONFIDENTIAL Miscellaneous commands ■ ■■ ■■ ■ DLE ENQ more EXECUTING COMMAND [Name] Real-time request to printer [Format] ASCII Hex Decimal [Range] 1≤n≤3 [Default] None [Description] Responds to a request from the host specified by n. The operations performed depend on the value of n, as follows: n = 1: Recover from an error and restart printing from the line where the error occurred. n = 2: Clear the receive and print buffers and recover from an error. n = 3: Cancel waiting for validation.
CONFIDENTIAL ■ DLE ENQ 1 restarts printing from the line where the error occurred. This command is available only for recoverable errors other than a print head temperature error. ■ DLE ENQ 2 enables the printer to recover from an error after clearing the data in the receive and print buffers. The printer retains the settings (from ESC!, ESC R, for example) that were in effect when the error occurred. Using DLE ENQ 2 and ESC @, the printer can be completely initialized.
CONFIDENTIAL Miscellaneous commands ■ ■■ ■■ ■ DLE DC4 more EXECUTING COMMAND [Name] Generate pulse at real-time [Format] ASCII Hex Decimal [Range] n=1 0≤m≤1 1≤t≤8 [Default] None [Description] Outputs the pulse specified by t to connector pin m as follows: DLE 10 16 DC4 14 20 n n n m m m t t t m Function 0 Drawer kick-out connector pin 2 1 Drawer kick-out connector pin 5 • [Notes] The pulse ON time is [t × 100] ms, and the OFF time is [t × 100] ms.
CONFIDENTIAL ■ This command should not be used within the data sequence of another command that consists of two or more bytes. If you attempt to transmit ESC ! n to the printer, but DLE DC4 105 interrupts before n is received, the code <10>H for DLE DC4 is processed as the code for ESC ! <10>H. ■ This command is enabled even when the printer is not selected by ESC =.
