3 Communication Protocol
3.1 Type of Communication Protocol
There are four types of communication protocols available for the WS4 series such as;
(1) READY/BUSY
(2) XON/XOFF
(3) STATUS3
(4) Protocol for driver (STATUS4)
Each interface uses different communication protocol.
In each communication protocol, the printer returns the status corresponding to the command requested by the host
computer. There are two types of return status formats.
(1) STATUS3 type
(2) Protocol for driver (STATUS4) type
The following table shows the compatibility of communication protocol and interface. Note that the return status
formats are indicated by the symbols below.
