Abstract
A printer driver is provided in a host computer. When a print job occurs, the printer driver automatically selects the format of a plotting command to be output to a printer. As the command format, there are available two kinds of formats: a high-level printer control language format (for example, PDL), and an intermediate code format expressed in an intermediate language. When the latter format is selected, the printer driver converts a plotting command from an application to an intermediate code and then outputs the intermediate code to the printer. The printer converts the intermediate code to another intermediate code specific to the printer by a very simple processing, and then develops the intermediate code to a bit image, thereby enabling high speed printing.
