Start Raster Transfer - Brother HL-Series Technical Reference Manual

Revision C 16/01/96
• # = 1024 indicates the TIFF format. This is valid only for 600 dpi data. The raster graphics data is transferred
with the ESC*b###W (### = data length) command. The TIFF file follows this mode set command. This
printer does not support LZW compression. Pages that contain TIFF data are printed in the gray scale mode.
The TIFF data contains the header, tag, and print data.
This mode supports TIFF Version 5.0 file format. In this mode, transfer graphics data command by te count
does not have a limitation of 32,767 byte. Ths printer supports bothe "MM" (big endian) format and "II" (little
endian) format. Print model is not applied to this type of data transfer. The printer has some limitations on
the TIFF format.
1. Tags position has to be prior to the picture (strip) data.
2. Compression tag - Tag ID : 259
3. Sample/pixel - Tag ID : 277
4. Bits/Smple - Tag ID: 258
5. Horizontal resolution (Tag ID=282) and Vertical resolution (Tag ID=283)

No Compression
No Compression
CCITT G3 & G4
We recommend 150 dpi or less resolution for APT to reduce data size.
• # = 1025 indicates the Brother origianl Compression Method.
• # = 1026 indicates the Brother Advanced Data Transfer Mode.

Start raster transfer

Esc*r#A
• This command signals the start of the transfer of a raster image to the printer.
• # is 0 or 1.
• # = 0 denotes that the image will be printed starting from the left edge of the logical page.
• # = 1 denotes that the image will be printed starting from the current cursor position.
• The transfer of raster data to the printer continues until either an End Raster Transfer command is sent or a
command other than Send Raster Data, Set Compression Mode, or Set Raster Y-Offset is sent.
The printer supports 1, 2, 3, 4 and 32773.
1 : no compression (Bits/Sample=1,4,8)
2 : CCITT G3 MH (Bits/Sample=1)
3 : CCITT G3 MR (Bits/Sample=1)
4 : CCITT G4 (Bits/Sample=1)
32773 : Pack Bits (Bits/Sample=1)
This value should be 1. This means the printer accepts only monochrome TIFF file.
The printer supports 1,4 and 8.
If you specify 4 or 8 and the printer resolution is 600 dpi, the printer prints that the page utilizing
APT.
