Abstract
In order that the reception buffer of a host based printer is unlikely to become full with image data transmitted from a host computer and to reduce the number of print interruptions caused by the fullness of the reception buffer, it is determined whether the reception buffer is in a first buffer-full state or in a second buffer-full state. The first buffer-full state is a state in which the reception buffer is full with image data and a page end code. The second buffer-full state is a state in which the reception buffer is full with image data but no page end code is contained therein. In the first buffer-full state, printing has already been started upon detection of the page end code and so an interruption signal for interruting the printing procedure will not be generated. In the second buffer-full state, an interruption signal is issued to start an in-advance printing if printing has not yet been started. When printing has already been started, no interruption signal is issued so that printing procedure can be continued.
