1.2Host PC Function1.2.1PC PRINTER Function

1)Performs a coding compression of a raster image data in Host PC, and by using Hiper-W command (ORIPL), encoded data is transferred to Fax machine at high- speed (MCE mode) and printed as decompressed decoded data in sub-system side of the machine (printer).

Compression mode: ACC32

2)By using Hiper-W command (OPEL), it is possible to read a status of the machine (printer) and establish an environment setting.
