Patent ID: 8111427

Claim:
An information processing apparatus for outputting print data to an external image-forming apparatus connected to the information processing apparatus through an interface, the information processing apparatus comprising: identifying means for identifying a type of the interface; designating means for designating either one of an automatic function and a specific quantization method to designate a quantization method for the print data; automatic determining means for determining, when the automatic function is designated, a first combination of the quantization method with a compression method for the print data based on the type of the interface identified by the identifying means; determining means for determining, when the specific quantization method is designated, a second combination of the designated specific quantization method with a compression method for print data corresponding to the designated specific quantization method; image processing means for quantizing the print data and compressing the quantized print data based on the first combination of the quantization method and the compression method determined by the automatic determining means or the second combination of the quantization method and the compression quantization method determined by the determining means; and output means for outputting the print data processed by the image processing means to the external image-forming apparatus through the interface.
