SPRT

3.1 Parallel Interface Connection

SP-T printers adopt D-25 parallel interface, which is compatible with
CENTRONICS standard, and the interface socket matches well the print
interface of IBM PC. So, if you connect the printer to IBM PC, LAPTOP
portable computer etc. hosts by using the cable said in Appendix 5 directly,
you needn't to worry the plug and socket connected incorrectly. There are
several kinds of cable accessories shown in Appendix 5 of this manual for
selection, you can select to use according to your printer's interface. If
there is no suitable cable in Appendix 5, you may specially order the cables
according to the signals of SP-T printers' parallel interface and host
interface.
The pin order of parallel port is as Fig. 3-1 shows:
The pin assignment of parallel interface is shown in Fig. 3-2, signal level is
TTL standard:

Description
Strobe pulse to latch data,
reading occurs at falling edge.
These signals represent the 1
th
bit to 8 bit of the parallel data
representatively, each signal is
at HIGH level when data is logic
1, and LOW when data is logic
0.
