Host apparatus and system to control duplex printing and method thereof

摘要

A method of controlling duplex printing and a host apparatus and a system for performing the method. The method includes determining whether a number of total printing pages of printing data is an even number or an odd number, generating a printing command with respect to the printing data based on the result of determination, and transmitting the generated printing command and the printing data to an image forming apparatus.

1. A method of controlling duplex printing of a system comprising an image forming apparatus including a duplex printing function and a simplex printing function and a host apparatus to transmit printing data to the image forming apparatus, the method comprising:
determining, by the host apparatus, whether a number of total printing pages for the printing data is an even number or an odd number greater than or equal to three; generating, by the host apparatus, if the number of total printing pages is the odd number greater than or equal to three, a first operation and a second operation, where the first operation includes a duplex printing command and a duplex printing data which corresponds to the pages except the last page in the printing data and the second operation includes a simplex printing command and a simplex printing data corresponds to the last page in the printing data; and transmitting, by the host apparatus, the generated first and second operation separately to the image forming apparatus.
