Printing system and printing method for increasing efficiency by selectively rasterizing print data in either a host device or a print device

摘要

A printing system comprises a host device like a personal computer (PC) which creates print data (GDI data) based on an application, and selects through which a conversion process either a first conversion process of converting the data into PDL data or a second conversion process of converting the data into image data should be executed based on the performance of the host device connected to a printing device, the kind of the application, and the like when performing the conversion process on the print data and transmitting the converted data to a printing device, and further selects the conversion process based on a command in GDI data, a data size, and the like, thereby automatically selecting the most efficient printing scheme, and the printing device which prints out the print data transmitted from the host device.
