• When the XON/XOFF control is selected, all the codes are sent continuously without verifying that the host can receive the data. Data that has been sent is always continuous except for

 

the XOFF code.

 

• When parallel interface is used, the size of the buffer for

 

sending data (The buffer that stores all data to be sent except

 

for ASB status) is 99 bytes. Data which exceeds 99 bytes, will

 

be discarded.

 

• Data can be written into the download user NV memory using

 

the FS g3 command.

 

• There may be a delay between receiving this command and

 

storing the data depending on the state of the receiving buffer.

[Caution]

• After the header is sent, all data will be sent without verifying

 

whether the host can receive the data or not. Therefore, the

 

available space in the receiving buffer of the host should be

 

more than (The number of sent data+2) in order not to lose

 

data during the execution of this command.

 

• While data is being sent, real time commands (Commands

 

with a DLE extension) will be ignored. And even if the ASB

 

function is validly selected, ASB status will not be sent while

 

data is in the process of being sent. Therefore, it is not possible

 

to check the change in the printer state by checking its status.

 

The user must pay attention to this.
