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 LZ W 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)
