Extended System-Level Command Functions
(PT) Tear Position – This command sets the label stopping location at the tear plate on the
printer's cover.
Note: Not recommended for use with non-display printers, instead see Stop Location (SL).
(PV) Paper Value – This command sets threshold value for the media sensor's 'paper' parameter.
(PW) Password – This command modifies the numeric password required to access the menu
system when security is enabled. If security is enabled, enter the new password followed by the
old password (with no spaces) in this form: XXXXXXXX
(QQ) Configuration Query – This command requires a parameter of either K or Q. K causes the
printer to respond with the Printer Key, used for generating Upgrade Codes. A parameter value
of Q causes the printer to respond with the current configuration settings. The <STX>Kc
response command stream format is sent to the host computer via the same port as the query
containing all parameters controlled by the <STX>Kc command, and may be used for restoring
the printer's configuration or for configuring other printers.
(RA) Row Adjust – This command shifts the vertical start of print position (in dots) to fine-tune
the Row Offset setting to compensate for slight mechanical differences sometimes evident if
multiple printers share label formats. Note that the accepts this command for backward
EX2
compatibility only, limited in range (28-228). <STX>KcQQQ response shows the Row Adjust
Fine Tune (RF) equivalent value.
(RB) Reflective TOF Bias – This command allows the manual entry for the control voltage level
to recognize a label "gap" or "mark."
