Sixel Graphics Considerations on the
LA310 MultiPrinter
This chapter explains the graphics resolution capability of the LA310
MultiPrinter.
13.1 Graphics Resolution
Since the LA310 does not support a physical horizontal resolution of 1/660", it
needs to ‘‘fall back’’ to a different grid size when some grid sizes are requested.
Table 13–1 shows the values that the LA310 uses for the macro parameter
(Ps1) of the Sixel Graphics mode protocol selector.

>9 1/144" (.0069) 200:100 200:100
Table 13–2 shows the horizontal grid size (HGS) and vertical grid size (VGS)
fallbacks relative to the requested horizontal grid size and the aspect ratio.
