Chapter 1.0 1.1 Control Characters Printer Character Set 1.0 Unitech MP200 Printer Character Set Character Sets can be grouped into 3 categories – Control Characters, ACII Print Characters and Extended Print Characters. • • • • • • • • • • Control Characters Defined as character encoding {0x00..0x1F} Designed to control the printer operation ASCII Print Characters Defined as character encoding {0x20..
Chapter 2.0 1.2 Printable Character Sets The printer has two resident character sets – namely Courier International and Courier PC Line Draw. Two commands are defined to select these character sets. Command String Selected Character Set Esc – ‘F’ –‘ 1’ Courier International Character Set Esc – ‘F’ –‘ 2’ Courier PC Line- Draw Character Set Printer Font Control 2.0 Unitech MP200 Printer Font Control Table 1.
2.2 Character Height Control Commands A single byte control command is defined to control the printed character height. Normal height of a character is 23. EXTEND control character (^ \) selects a double height, which is equal to 46. EXTEND OFF control character (^]) selects a normal height. The command is applied to all the characters on a line following the control character.

5.2 Printer Peak-Power Control Command The peak power control commands enable the operation of the printer with wide range of battery chemistries and peak capacities. The printer may be operated in five peak-power modes, as listed in the table below Power Mode Command Maximum Dots Selected Maximum Current 1- Low Esc-‘P’-0x01 Heat < 64 elements at a time Less than 1.0 Amp 2- Medium Esc-‘P’-0x02 Heat <128 elements at a time Less than 2.
Chapter 6.0 5.6 Supervisory commands Single byte supervisory commands are designed to provide the user of the printer with the current battery and print buffer status. The single byte supervisory commands and serial RS232 response strings are summarized below. Note: <4 ASCII hex digits> are read as hex nibbles ORed with 0x30.

Chapter 8.0 Appendix B Three Track Magnetic Card Reader Option A three track Magnetic Card Reader is available on the Unitech MP200 model printers. The MC reader is designed to read magnetically encoded data from cards conforming to ANSI/ISO 7810, 7811 standards. The MC reader converts the F2F encoded signals on the magnetic card, to ISO7811 compatible ASCII format and transmit the information to the host computer or a terminal.
are summarized in the tables below. The general syntax for commands is as follows: Command String – General Syntax <’M’>< n> Track #CR Command String - Example <’M’> ‘9’ ‘ 9’ 1 CR Table B.1 – Magnetic Card Read Command Strings – general form • The ESC-M command turns on the power to the MC Reader • The next two bytes, are used to set the MC reader’s timer. “01” through “99” are valid timer settings and “00” disables the timer.
Chapter 9.0 computer or a terminal. • The Host Selects the printer by activating the RTS input line or sending wake-up characters to the printer. • The Printer Sends the XON command to the host to indicate that it is ready to receive data from host. • Once XON is received the host sends ASCII serial command string to enablethe magnetic card reader (e.g. Esc-m004-cr). The printer turns on the GREEN LED.

Chapter 10.0 C.3.1 The Bluetooth™ interface power modification The Bluetooth™ interface increases the battery power consumption by 50 milli Amp. To compensate the increased power demand, the trickle charge rate is modified to help extend the life of the internal battery cartridge. The printer modification is such that the printer can be set to operate in either the MANUAL POWER OFF or CONTINUOUS ON mode of operation. C.3.
