6.2 Explanation of Terms
1) Receive buffer
The receive buffer is a buffer that stores, as is, the data received from the host. The data is stored
in the receive buffer temporarily, and is then processed sequentially.
2) Print buffer
The print buffer is a buffer that stores the image data to be printed.
3) Print buffer full
This is the state where the print buffer is full. If new print data is input while the print buffer is full,
the data in the print buffer is printed out and a line feed is executed. This is the same operation as
the LF operation.
4) Start of line
The start of line state satisfies the following conditions:
•
There is no print data (including spaces) currently in the print buffer.
5) Printable area
The maximum range within which printing is possible under the printer specifications. The
printable area for this printer is 84.5 mm.
6) Ignore
The state in which all codes, including parameters, are read in and discarded, and nothing happens.
