M – Memory Allocation, cont.
Formulas for calculating the theoretical requirement of SRAM
memory for a label (X) in Kbytes:
8 dots/mm (203.2 dpi):
X = [(Height in mm x 8) x (Width in mm x 8)]/ (1024 x 8)
or
X = [(Height in inches x 203.2) x (Width in inches x 203.2)]/(1024 x 8)
11.81 dots/mm (300 dpi):
X = [(Height in mm x 12) x (Width in mm x 11.81)]/ (1024 x 8)
or
X = [(Height in inches x 305) x (Width in inches x 300)]/(1024 x 8)
Because of the way the memory is organized, a slightly larger
amount of memory may be required.
Form Memory
The Form memory is for permanent storage of label forms in
fl ash. A form requires 1 kbyte or more of memory.
Graphics Memory
The Graphics memory is for permanent storage of label graphics
in fl ash. Avoid storing frequently changing graphics in fl ash
using a
buffer using a
prolongs the life of the fl ash memory.
Resetting the memory via the serial port:
Examples
The example below formats the memory to allocate extra
memory to the graphics memory at the expense of the external
fonts memory, whereas the size of the form memory is retained at
default value.
Note that the memory allocation values returned for example by
a U
an M command because of certain round off calculations in the
fi rmware. This should have few practical consequences and can
generally be ignored.
