Extended System-Level Command Functions
(ET) Exact Time – This command set the printer to wait until the system is idle before the next
label's data and time fields are formatted to eliminate any discrepancy between the buffered and
printed times.
(EV) Empty Sensor Level – This command sets threshold value for the 'Empty' media sensor
parameter.
(FA) Format Attribute – See the "An" (in Label Formatting Command Functions) command for
details.
(FE) Font Emulation –This command allows font substitution for all Datamax internal fonts,
allowing a new default font to be defined without changing the host DPL data streams. Selecting
a default font that supports a desired character set could match with third party software to print
native characters without modifying the PC drivers. In other words, match the PC font with the
Printer Font then no interpretation would be required by driver or printer. Depending on host
drivers, the user may have to disable Symbol Set commands and modify the Default Symbol set.
