Table appendix 4.2-1 parallel signal list
Caution:
In the process of data transmission, the host computer should not ignore the Busy signal; otherwise the
print data may be lost;
Parallel interface signal adopts TTL level. Ensure the rise and fall time of host computer is not longer than
0.5
s when it is used.
Appendix 4.3 USB interface
USB interface meets USB1.1 protocol standard and is optional.
USB interface transmits signal and power via a four
–wire cable, as shown in the following figure:
Figure appendix 4.3-1 USB cable
Wire D+ and D- in figure appendix 4.3.1 are used for signal transmission, and the VBUS is +5V.
Appendix 4.4 Ethernet interface
Ethernet interface meets the standard communication protocol of 10/100M BASE-T in IEEE802.3 and is
optional.
