· Cause of receive buffer near full
Buffer near-full occurs when the remaining capacity of receive buffer (2.95MB) becomes 0.95 MB.
· Factors to release receive buffer near full
Receive buffer near full is released when the remaining capacity of the receive buffer becomes 1.95 MB or more.
*Occurrence of buffer-over depends on the interface.
[o: Interface that buffer-over occurs, x: Interface that buffer-over doesn't occur ]
(4) ENQ respond delay time setting
You can use the delay timer function to delay returning the printer status to the host by setting [ENQ respond delay time]
in the service mode. Refer to the “Operator Manual” for more setting details.
*1 Time period of "+α" varies according to the interface or the behavior of the application in the host.
*This function is invalid in the cyclic response mode when using LAN interface.
2) Cancel request command
This command enables to cancel print jobs and to clear the entire contents of receive buffer.
The printer returns the printer status of after completion of the current process.
*When the cancel request command has sent, wait more than 500 ms before sending the next data.

3) Print Command
Print command (<A>～<Z>) starts the printing process.
The printer returns the printer status after receiving process is completed.
