1. SCOPE This specification applies to the external equipment interface for use with the TPCL (TEC Printer Control Language) of the B-850 general-purpose thermal label/tag printers. 2. GENERAL DESCRIPTION The external equipment interface connects a printer to the host computer through a serial interface (RS- 232C), parallel interface (Centronics), or a network for making various settings and printing labels. PCL emulation (Printer Control Language for Hewlett Packard laser printer) is enabled by

XON/XOFF (DC1/DC3) Protocol + READY/BUSY (DTR) Protocol When initialized after the power is turned on, this printer becomes ready to receive data and turns the DTR signal to the “High” level (READY). The printer also sends an XON code (11H). When the blank positions in the receive buffer are 800 bytes or less, the printer turns the DTR signal to the “Low” level (BUSY) and sends an XOFF code (13H). When the blank positions in the receive buffer are 2K bytes or more, the printer turns the DTR

nInit (Printer ← Host) Reset request signal from the host Normally at the “High” level. A low on this input causes the printer to be initialized in the same manner as when the power is turned on. When the nInit signal is input during printing, the printer completes printing one label which is being printed, cancels the next processing, then is initialized in the same manner as when the power is turned on.

+5 V This is not a signal but a +5 V power supply voltage. The maximum current of 500 mA can be used for external equipement. IEEE1284 Active (Printer ← Host) The signal is used with the HostBusy signal, to request the data transfer in the IEEE1284 mode, or to request the end of the IEEE1284 mode. To request the data transfer in the IEEE1284 mode, the host sets the IEEE1284 Active signal and the HostBusy signal to high and low, respectively. To request the end of the IEEE1284 mode, the ho

Receiving data when the blank positions in the receive buffer are 712 bytes or less: When the blank positions in the receive buffer are 712 bytes or less, the printer stores the received data in the receive buffer, continues to be in a BUSY state (BUSY signal at the “High” level) for 10 seconds to extend the data read interval when data is set from the host, and reads the data 10 seconds later. If the blank positions become 713 bytes or more while waiting for reading data, the printer will re
