Double Buffering EPL2 printers with firmware version 3.0 and
higher (except TLP2046) support double buff
-
ering of print images to increase through-put.
The printer can print the image out of one buffer
while loading an image into a second image
buffer, if sufficient memory is available to load
the second image. The printer will automatically
test and enable double buffering. Double buff
-
ering allows the printer with most image formats
to print continuously.
If a sufficient amount of image buffer memory is not
available to double buffer print images, then the
printer will load a print image and then print, per
-
forming these functions one label at a time.
While operation of the Double Buffering feature
is automatic, the following are requirements to
enable the feature:
The Q command must be used to establish
the height of each label and initiate double
buffering.
The q command must be used to match the
width of the image buffer to the width of the
label. The q command will maximize and test
the image buffer if sufficient memory is avail-
able to enable double buffering.
The amount of (SRAM) memory allocated
(with the M command) for the image buffer
must be large enough to hold the two label
images. Using the formulas below, calculate
the memory requirements for each label.
Add the memory requirements for each label
to determine the total image buffer memory
requirements.
Flash Memory Printers - The M command does
not affect the image buffer size in flash memory
based printers. The image buffer is a fixed size.
