Printer BUSY conditions and the Msw1-3 status

4.2.2.4 Receive buffer

The capacity of the receive buffer is set using memory switch setting mode or memory switch
Msw1-2. The definition of a receive buffer full is described in the following table.
The printer ignores the data received when the remaining space in the receive buffer is 0 bytes.
Note:
When using OPOS or Advanced Printer Driver, you don't need to change the receive buffer.
4.2.3 Label peeling sensor (peeler specification only)
This detects whether or not there is a peeled label. If a label is removed, the next label is moved
to the printing start position.
Note:
If the printer is used in a location with direct sunlight, even when a label is removed, it may be determined
as being present due to misdetection, and the printer continues waiting for label removal status. In this
case, press FEED once to return the paper to the next label printing start position.
Printer status
Memory switch Msw 1-3 state
ON OFF
Offline During the period from when the power is turned on
(including resetting using the interface) to when the
printer is ready to receive data.
BUSY BUSY
During the self test. BUSY BUSY
When the cover is open. - BUSY
During paper feeding using the paper feed button. - BUSY
When the printer stops printing due to a paper-end.
(only when the roll paper is not present)
-BUSY
When an error has occurred. - BUSY
When the receive buffer becomes full. BUSY BUSY

Buffer full definition
ON 45 bytes From when the remaining space in the receive buffer drops to 16 bytes,
to when the space increase to 26 bytes.
OFF 4 Kbytes From when the remaining space in the receive buffer drops to 128 bytes,
to when the space increase to 256 bytes.
