Image processing appartus which processes a plurality of command languages
 An image processing apparatus for receiving a plurality of data groups, each of which belongs to a different command system of an external apparatus. A data analyzer is included in each command system. A data receiver receives the data from the external apparatus, and a judgment is made as to whether each of the data groups received by the data receiver contains the data analyzer corresponding to the command system of the corresponding data group. A print controller bypasses a data group of a command system judged not to include the data analyzer, and printing is disabled for that data group.
