(UD) User Label Mode – This command places the printer in standalone operation,
which provides menu-driven processes to print user defined files, including
. dlb,
.dpl, .prn, .txt
formats.
(UM) Units of Measure – See <STX>m (metric) or <STX>n (imperial) for command
details.
(UN) Plug and Play ID Type – This command controls the type of Plug and Play ID
supplied; where Y is for unique and N for static.
(UT) User Terminator – This command allows word wrapping of long character
strings of commands to the next line in a file, for the purposes of readability only. In
the <STX>Kc string, the command UTON must fall somewhere before the first line
terminator. The last command needs to be END, followed by a line terminator (see
the <STX>KcEN command for details).
(VE) Verifier Equipped – This command enables the GPIO for a bar code verifier
(see Appendix J). A (or Y) - automatically senses device presence; if undetected, no
error is generated. E - enables the device, where its presence must be detected;
otherwise, a fault is generated. N or D - disables device detection.
(VT) Verifier Type – This command is reserved for future use.
