When using the Datamax printer driver (Ver. 2+) with either of the following printers (Prodigy Max, DMX 600 or DMX 800), a letter O (capital O) prints instead of the number zero (0). If using the Fargo printer driver (Standard), the number zero (0) prints correctly.
This is a printer firmware bug. The current firmware versions that have the bug are: Prodigy Max — 1.32 or earlier DMX 600 — 2.19 or earlier DMX 800 — 2.19 or earlier When using the z printer command (Zero Conversion from slashed zero to non-slashed zero) and downloading a font to the printer, the printer will convert the normal zero (an unslashed zero) to the capital letter O. Smooth fonts, such as TrueType fonts, do not have a slashed zero, yet the printer is converting the zero anyway.
1.) Datamax fixed in firmware version 3.12. 2.) EASYLABEL was modified (version 2.0) to include a new configurable option. (Use Slashed Zero if available or not to use a slashed zero.)
