Note 1 The distance between the beginning of the line to the print position is [(nL + nH x 256) x (vertical or horizontal motion unit)] inches. 2 Setting outside the specified printable area is ignored.
P25 Development Guide [Note] 1 The command is enabled only when processed at the beginning of the line. 2 This command formats the justification in the printing area. 3 This command justifies the space area according to HT, ESC $ or ESC \ [Default] n = 0 HT [Name] Horizontal Tab [Format] ASCII HT HEX 09 Decimal 9 [Description] Moves the print position to the next horizontal tab position. [Note] 1 This command is ignored unless the next horizontal tab position has been set.
P25 Development Guide 4 This command cancels the previous horizontal tab settings. 5 If you set n=8, the print position is moved to column 9 by sending HT. 6 Up to 32 tab positions (k=32) can be set. Data exceeding 32 tab positions is processed as normal data. 7 Transmit [n]k in ascending order and place an NUL code 0 at the end. 8 When [n]k is less than or equal to the preceding value [n]k-1, tab setting is finished and the following data is processed as normal data.
P25 Development Guide 2.
P25 Development Guide 5 d indicates the bit-image data. Set a corresponding bit to 1 to print a dot or to 0 to not print a dot. 6 If the width of the printing area set by GS L is less than the width required by the data sent with the ESC * command, the following will be performed on the line in question (but the printing cannot exceed the maximum printable area).The width of the printing area is extended to the right to accommodate the amount of data.

P25 Development Guide UART0 (BT port) default Baud Rate is 38400, and it cannot be changed. If set baudrate to 0, then back to default baudrate. (Since S1.0.42) The default Baud rate in the bootloader firmware is 115200, and it can not be changed. These commands are only used to adjust the Baud rate in the application of the P25. Furthermore, the change will be affect only after you restart the printer.
P25 Development Guide 2.10 Enter/Quit Bridge Mode Commands These commands are used to switch the P25 printer between normal mode and bridge mode. P25 printer has two working modes, one is normal mode, and another is bridge mode. In the normal mode, P25 can accept and print data both in Blue Bamboo frame protocol and plain text protocol. When the printer is in the bridge mode, P25 can receive and print data in Blue Bamboo frame protocol as same as in the normal mode.
P25 Development Guide 2.11 Realtime Commands OVERVIEW Character Data and Normal Commands The printer stores data sent from the host computer in the receive buffer temporarily, and then the printer interprets the data and classifies them into commands or character data sequentially.
P25 Development Guide The transmitted battery status from this printer is constructed by [Header ~ NUL] as shown in the following table. Transmitted data Header Identifier Power source (*1) Battery remaining amount (*2) NUL Hex 37H 45H 31H 30H-33H 00H Decimal 55 69 49 48-51 0 Amount of data 1 byte 1 byte 1 byte 1 byte 1 byte (*1) “Power source” must be 31H, indicates is power by battery. (*2) “Battery remaining amount” is as indicated in the following table.
P25 Development Guide 3. Introduction of Communication Protocol The P25 printer supports two types of communication, plain text protocol and framing protocol, Plain text protocol is much simpler however with limited features. The framing protocol supports more features and is recommended. Those two protocols can be automatically interpreted on the fly by the P25. 3.
P25 Development Guide The items marked ‘X’ must be present during the entire communication process. The items marked ‘O’ must be present during certain parts of the process. During transmission, if C0H, C1H, and/or 7DH are shown in the DATA field, 7DH should be inserted before the data and the data should be XORed with 20H and sent. During reception, if 7DH is encountered, 7DH should be ignored and the next byte should be XORed with 20H and stored. 3.
P25 Development Guide 3.4 Printing or Downloading Data Figure 2: Process of printing data Figure 3: Process of software update Note: The “Sending ENQ frame” is optional, it just let app know whether print is working normally, customer could print data without sending this frame (that is only sending data frame). In normal operation, after receiving the print data frame, the printer sends EOT, prints out the data, and sends ETX; then it will wait for the next frame.
P25 Development Guide 3.4.1 Format of Printing or Downloading Data Frame C0H (SOF) ‘D’ (0x44) (TOF) DATA ID Number DATA Length DATA CHECK SUM C1H (EOF) 1 Byte 4 Bytes Data 2 Bytes When printing data or downloading data to the printer, the communication protocol should comply with the upper communication structure. Data ID number: ‘0’~‘9’ (0x30~0x39). Every time the host sends a new print data frame, it increases this number. Data Length: “0001” ~ “3000”.

The basic steps to set up a Bluetooth SPP connection are: • Inquiry: Find nearby devices in range. This will result with all access points responding with their address. • Paging: The device will invoke a baseband procedure called paging.
