Extended System Commands
Introduction
Extended System Commands expand certain System-Level Commands, providing extra printer control.
Extended System Commands are issued in the same context as System-Level Commands. The table below
lists the commands.

STX K Memory Configuration
This command configures the available DRAM as a method for managing printer memory. The
DRAM memory includes standard DRAM. Memory can be assigned to specific entities or functions
in units of 4KB blocks. The allocation(s) as set by this command, draw from the same memory pool,
control the sizes of internal Module A, Scalable Cache, and label width. The command indirectly
affects maximum print length and label throughput; see note below. The printer executes the memory
configuration specified by the command during the next idle period following its receipt, and is
stored in Flash memory then reinstated upon a power-up or reset. If the total requested memory
allocation exceeds the configurable memory available, contains no fields, or for configurations not
specified, the command will be rejected and the printer will assume its previous configuration. Any
of the three fields are optional, and are separated by the colon. Brackets indicate optional fields.
Syntax:
<STX>Kix[:jy][:kz]<CR>
Sample:
<STX>KM0020:S0015<CR>
In the sample, memory is allocated 20*4*1024 bytes for Module A space and 15*4*1024 bytes for
the scalable cache.
