4-2. 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 only.
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), executing the buffer clear command (49h) or by turning the power off and on
again. This command clears the rasterized image register buffer.

(2) Buffer clear command
This command clears the rasterized image register buffer and print expansion 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 buffer clear command (49h)
or by turning the power off and on again.
