Print and Erase Commands

The speed to write and erase switches according to the ambient environment and card media.
To perform a timeout, set the timeout value according to the environment of use.
(1) Print expansion buffer clear command
This command clears the print expansion buffer.
Image data is expanded in the print expansion buffer by the character (including external
characters) by the print character data setting command (41h), and the internal image data
expansion command (42h).
The reader/writer prints the contents of the rasterized image register buffer with the print
expansion buffer by the erase + print command (46h), but data remains in both buffers, so if the
erase + print command (46h) is executed again, the same print results will be attained.
The print expansion buffer is cleared only by executing the print expansion buffer clear
command (40h) or by turning the power off and on again.

(2) Rasterized image register buffer clear command
This command clears the rasterized image register buffer.
The rasterized image data transmitted from the host is expanded in the rasterized image
register buffer.
The reader/writer prints the contents of the rasterized image register buffer with the print
expansion buffer by the erase + print command (46h), but data remains in both buffers, so if the
erase + print command (46h) is executed again, the same print results will be attained.
The rasterized image register buffer is cleared only by executing the rasterized image register
buffer clear command (49h) or by turning the power off and on again.
