Introduction
This manual covers both the 224 and 424 printers. The primary difference in the two
printers is print width. The 224 uses a 2.1 inch (53mm) print head and the 424 uses a 4.1
inch (104mm) print head. Both printers are offered with a standard resolution of either 203
dpi (8 dots/mm) or an optional 300 dpi (12 dots/mm). The print mechanisms of the 224 and
the 424 printers utilize different parts to account for the difference in print width. Otherwise,
the printers are virtually identical. This manual will use the 424 for illustration purposes.
