For further information about the CCITT G3/G4 data format, please refer to CCITT (The International Telegraph and Telephone Consultative Committee) BLUE BOOK Volume VII.

•# = 1024 indicates 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 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, the transfer graphics data count does not have a limitation of 32,767 bytes. This printer supports both "MM" (big endian) format and "II" (little endian) format. The Print model is not applied to this type of data transfer. The printer has some limitations on the TIFF format as follows:-

1.Tag position has to be prior to the picture (strip) data.

2.Compression tag - Tag ID : 259

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)

3. Sample/pixel - Tag ID : 277

This value should be 1. This means the printer accepts only monochrome TIFF files. 4. Bits/Sample - Tag ID: 258

The printer supports 1,4 and 8.

If you specify 4 or 8 and the printer resolution is 600 dpi, the printer prints the page using APT.

5. Horizontal resolution (Tag ID=282) and Vertical resolution (Tag ID=283)

Compression type	Bits/Sample	Available Resolution	APT
No Compression	4,8	From 1 dpi to 300 dpi	ON
No Compression	1	Printer's Resolution	OFF
Pack Bit		(300 or 600 dpi)
CCITT G3 & G4	1	200,300,400,600 dpi	OFF
		400 & 600 dpi are only available
		when the printer operates in 600
		dpi mode.

We recommend 150 dpi or less resolution for APT to reduce data size.

•# = 1025 indicates the Brother original Compression Method.

•# = 1026 indicates the Brother Advanced Data Transfer Mode.
