The RWRF W command writes data to an external device such as the hard disk.
The available number of fonts is max. 512 in the same compact flash and max. 4096 in
the hard disk.
Duplicating a file name causes the system to rename the specified one and save data
(without overwriting data).
For Japanese TrueType Font Collection, the print system automatically appends (P) for
proportional fonts and (F) for fixed pitch fonts. If TrueType Font Collection contains
three or more fonts, the print system automatically appends (1), (2), (3)...(9).
You can omit the parameters ranging from symbol-set-value to typeface; however, you
should not omit those font attributes to exactly select a font.
The length of the font data to be written must match the specified one. Failure to do so
will result in an error, and disables you to write data.
Specify WRED; command following <binary data>. "WRED;" (five bytes) are not
included in the font data length.
To delete the registered Japanese TrueType font, use the RWRF D command.
To write font data in the external media, you need to have the owner grant the intellectual
property right for fonts.
Example:
!R! RWRF W , 0 , "FNT" , "RSF" , "testfont"; [FontData]
WRED; EXIT;
!R! RWRF W , 0 , "FNT" , 0 , "testfile" , "testfont" , 619 ,
1 , 10 , 0 , 100; [FontData] WRED; EXIT;
