– 38 – 9. DA T A STR UCTURE AND CONTROL 9-1. DTR Mode (1 BLOCK) Controls Data Transfer by using DTR line as BUSY FLAG (a) (b) In case of Paper Empty Paper Empty When the paper out detector indicates end of paper, the printer stops printing after a maximum of two lines of printing or paper feed.
– 39 – 9-2. X-ON/X-OFF Mode The printer transmits an X-ON (Control Code; DC1, Hexadecimal Value; 11H,) signal after power is turned on, if there is no printer error being generated. When this signal is received by the host computer, the host computer transmits the data to the printer.
– 40 – Paper Empty When the paper out detector indicates end of paper, the printer stops printing after a maximum of two lines of printing or paper feed.
– 41 – 9-3. STX-ETX Mode The start of the STX-ETX mode should occur with a totally empty print buffer. This can be achieved by sending an ENQ code to the printer and checking the status until the status code indicates an empty buffer. At that point, the STX code is sent by the host computer followed by a data block.

– 46 – When printer power is supplied by the user rather than through the accessory power source unit, please be careful of the following points. Note 1: The power supply must be +12V 2A or above. An electrolytic ca- pacitor (C = 4700µF/25V to 6800µF/25V) must be connected across the output of the power supply.
