Item Description
Reception buffer
The reception buffer is a buffer that stores, as is, the data received from the host (the
reception data). The reception data is stored in the reception buffer temporarily, and is then
processed sequentially.
Print buffer The print buffer is a buffer that stores the image data to be printed.
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.
Start of line
The start of line state satisfies the following condition:
There is no print data (including spaces and portions of data skipped due to HT) currently in
the print buffer.
Printable area The maximum range within which printing is possible under the printer specifications.
