With the status flag set, and data reception prohibited,

the vacant area of the buffer gradually increases as the

printer continues to print. When the vacant area in the

buffer reaches the specified value (typically 512 bytes;

refer to your printer manual), the flag is reset and data

entry is again enabled.

Note

Reverse Channel pin (No. 11) and DTR pin (No. 20) are

internally connected on the interface board and must

have identical signal levels.

Printer status error

The flag will be set immediately regardless of the

remaining buffer capacity if the printer detects an error.
