Abstract

An image processing apparatus includes a first analyzing unit configured to analyze at least a first page data of print data, and a second analyzing unit configured to analyze at least a second page data of the print data. In a case where an error occurs in analyzing the second page data by the second analyzing unit before completing analyzing of the first page data, the second analyzing unit stops analyzing the second page data, and the first analyzing unit continues analyzing the first page data until analyzing of the first page data is completed, wherein the first page data proceeds to the second page data in the print data. The first analyzing unit and the second analyzing unit are implemented by one or more processors or circuitry, or a combination thereof.

Dependent claims

An image processing apparatus, comprising:

a first analyzing unit configured to analyze at least a first page of print data;
and
a second analyzing unit configured to analyze at least a second page of the print data;
wherein in a case where an error occurs in analyzing the second page by the second analyzing unit before completion of analysis by the first analyzing unit of the first page, the second analyzing unit stops analysis of the second page, and the first analyzing unit continues analysis of the first page until analysis of the first page is completed, thereby the first page is printed but the second page is not printed,
wherein in a case where an error occurs in analyzing the first page by the first analyzing unit before completion of analysis by the second analyzing unit of the second page, the first analyzing unit stops analysis of the first page and the second analyzing unit stops analysis of the second page, thereby neither the first page nor the second page is printed,
wherein the first page is to be printed before the second page is to be printed, if no error occurs;
and
wherein the first analyzing unit and the second analyzing unit are implemented by one or more processors or circuitry, or a combination thereof.
