OWNLOAD SINGLE BYTE FONT
Download a single byte font code page to the printer. If the download is successful, an ACK will be
returned. If unsuccessful, a NAK will be returned.
A font must always be downloaded completely, which corresponds to 224 characters.
The font name is used to identify the font. It will be printed on the diagnostics or configuration form. When
a downloaded font is to be deleted, the font name is used to identify the font. Two fonts cannot have the
same name.
Each character is downloaded as rasters, from top to bottom, and for each raster, from leftmost byte to
righmost byte.
The storage Id provides the operand for the ‘ESC t n’ (1Bh 74h n) command that will be used to select this
code page. Two fonts cannot have the same storage Id.
