# = 1152 indicates that CCITT G3/G4 data compression is to be used.
This format is popular in optical document storage areas as this compression is effective to store black and
white type pictures. As G3/G4 format does not have picture size/resolution information, the printer requires a
header at the beginning of t he picture data. The header size is 94 Bytes. Both the header and the picture data
are transferred by the ESC*b###W(###=data length) command. The normal PCL transfer graphics data
command has a limitation on the data size and ### should not exceed 32767. Unlike other modes, this mode is
special and does not have the 32767 size limitation. The data must have the following structure - Header and
Picture data. The values in this mode are little endians.
