Set Render Algorithm
Command
ESC*t#J (27)(42)(116)#(74) <1Bh><2Ah><70h>#<4Ah>
# = 0
Scatter dither
= 1
Snap to primaries
= 2
Snap black to white, all other colors to black
= 3 *
Scatter dither
= 4
Scatter dither
= 5
Monochrome device best dither
= 6
Monochrome scatter dither
= 7
Clustered dither
= 8
Monochrome clustered dither
= 9
User-defined dither
= 10
Monochrome user-defined dither
= 11
Scatter dither
= 12
Monochrome scatter dither
= 13
Scatter dither
= 14
Monochrome scatter dither
* Default value = 3
This command selects the halftone render algorithm.
• # = 1:
This does not use halftones. For 8 bits/pixel, for instance, any value over 128 is
transferred to 255, and any value under 127 is transferred to 0.
• # = 2:
This transfers black to white and other colors to black.
• # = 3:
This selects the scatter dither. The scatter dither is the most crisp dither (device best
dither) for the HL-2400C/Ce/3400CN/2600CN/3450CN/2700CN.
• # = 0, 4, 11, 13:
These show halftones using a dither method, which places dots in a dither pattern to
make the special frequency higher.
• # = 7:
This shows halftones using a dither method, which enlarges dots from their center.
• # = 9:
This shows halftones using the dither which is specified by the
Download Dither Matrix
command.
• # = 5, 6, 8, 10,
12, 14, 1025:
This replaces the color value with gray scale data using the formula below;
gray value = 0.30 x red + 0.59 x green + 0.11 x blue
5.2.
Set Monochrome Mode
Command
ESC&b#M (27)(38)(98)#(77) <1Bh><26h><62h>#<4dh>
# = 0 *
Monochrome mode off
= 1
Monochrome mode on
* Default value = 0
This command prints the color data by replacing it with gray scale data.
This command replaces the color data with gray scale data using the formula below;
gray value = 0.30 x red + 0.59 x green + 0.11 x blue
This command should be sent before sending the data to be printed. Failure to do so will cause the current
page to be closed and printed. This command may be sent on a page-by-page basis.
