Printer Commands Chapter 5

2. The Host then sends the printer the ^D149 command followed by the
raw image size that has been converted by the bmp2mic rev 1.02 or
later. Please note that the size is only terminated with a [CR] and the
[LF] is not included.
Example: ^D149[CR][LF]size[CR]
3. The printer will report back the image size back to the Host as an
indication that the printer is ready to receive the image.
Example: size[CR][LF]
4. The host then sends the converted image to the printer.
This image print protocol has a 5 second inter-character timer that starts as
soon as the printer sends back the size of the image. If the 5 second times
out, the download will fail. The printer will report >FAIL TIMEOUT<, the status
light will turn RED, and the printer will not respond to any commands until
receiving the Image mode clear command.
Image Mode Clear command:
ETBYKFNR
or in hex
45 54 42 59 4b 46 4e 52
The protocol will also fail if the image data is larger than the value entered
after the ^D149 command. The printer will report >FAIL SIZE<, the status light
will turn RED, and the printer will not respond to any commands until receiving
the image mode clear command.
The graphic needs to be downloaded each time it is to be printed as reprints
are not available in the D149 Image print mode. However, the format needs to
be downloaded only once. The label will print based on the last format that
was sent to the printer.
5.4.3 Contrast Adjustment Commands
These commands are used to adjust the darkness of the label print. Print quality will vary
not only with different label stocks, sometimes even in different batches of the same label
stock. It is highly recommended that contrast adjustments be maintained at minimum
settings to achieve desired print quality. Higher contrast settings will reduce the life of the
print head.
5.4.3.1 Adjust Contrast Window (Volatile - ^D35)
This command is useful for adjusting contrast for specific label formats where different label
media is used on a single printer. The command can be entered into specific label formats
rather than affecting print contrast on all label formats.
