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
Th e Form memory is for permanent storage of label forms in
fl ash. A form requires 1 kbyte or more of memory.
Graphics Memory
Th e Graphics memory is for permanent storage of label graph-
ics in fl ash. Avoid storing frequently changing graphics in fl ash
using a
GM command, but download them directly to the image
buff er using a GW command. Th e latter method is quicker and
prolongs the life of the fl ash memory.
Examples Resetting the memory via the serial port:
Th e 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 command may diff er slightly from the values entered using
an M command because of certain round off calculations in the
fi rmware. Th
is should have few practical consequences and can
generally be ignored.
