Extended System-Level Command Functions
63
(EQ) Start of Print – This command defines the type of signal input required to
control the Start of Print (SOP) process:
Value Units Start of Print Interpretation
3 Active Low
SOP signal must go low for at least 50 milliseconds to initiate
printing.
4 Active High
SOP signal must go high for at least 50 milliseconds to
initiate printing.
(ES) ESC Sequences – This command allows data containing invalid ESC control
code sequences to be processed (helpful because some systems send a “banner” to
the printer). When set to “Disabled,” ESC sequences are ignored and the data is
processed. Bitmapped font downloads are disabled in this mode.
(EV) Empty Sensor Level – This command sets threshold value for the “Empty”
media sensor parameter.
(FA) Format Attribute – See the “An” command for details (Label Formatting
Command Functions).
(FB) Scalable Font Bolding – This command sets a bolding factor to fine tune
scalable fonts, where one causes the least amount of bolding and thirty-six the most
(default value is 8).
(FE) Font Emulation –This command allows font substitution for all 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.
