Abstract

In case of temporarily spooling an intermediate language by a printer driver, a high speed print can be performed by suppressing a size and the number of holding data. The printer driver adds a tag of each draw object type to information of a draw command received through a DDI function and holds the resultant information into a primary buffer together with attributes such as draw position information, color information, pattern information, and draw logic information. When the information is held into the primary buffer, if there is a draw object which has already been held, if the types and the draw attributes of the draw objects are identical, the draw object is additionally registered into the primary buffer. If one of “type is different”, “data cannot be fully stored into the primary buffer”, “draw attribute changes”, and “page process is completed” is satisfied, a PDF (Page Data File) is generated from the draw object which has already been held in the primary buffer and spooled.

Dependent claims

An information processing apparatus that has a printer driver, said apparatus comprising:

primary buffer means for storing print command information input from an operation system to the printer driver;
memory means for storing one page of intermediate language data generated based on the print command information stored in said primary buffer means;
command decreasing means for, upon storing of the one page of intermediate language data in said memory means, if an attribute of print command information which has already been stored in said primary buffer means is identical to that of newly input print command information, generating new print command information based on the already stored print command information and the newly input print command information and allowing one page of intermediate language data generated based on the generated information to be stored in said memory means;
and
print job generation means for generating a job for a printer based on the one page of intermediate language data stored in said memory means,
wherein a number of commands of the new print command information generated by said command decreasing means is smaller than a total number of commands of the already stored print command information and the newly input print command information.

A computer-readable memory medium in which a program for controlling an information processing apparatus having a printer driver has been stored as a readable program, said program comprising:

a first storing step of storing, in primary buffer means, print command information input from an operation system to the printer driver;
a second storing step of storing, in a memory, one page of intermediate language data generated based on the print command information stored in said first storing step;
and
a command decreasing step of, when the one page of intermediate language data is stored in said second storing step, if an attribute of the print command information which has already been stored in said first storing step is identical to that of newly input print command information, generating new print command information based on the already stored print command information and the newly input print command information and allowing one page of intermediate language data generated based on the generated information to be stored in said memory;
and
generating a print job for a printer based on the one page of intermediate language data stored in the memory,
wherein a number of commands of the new print command information generated in the command decreasing step is smaller than a total number of commands of the already stored print command information and the newly input print command information.

A print control program embodied in a computer-readable medium for controlling an information processing apparatus having a printer driver, said program comprising:

a first storing step of storing, in primary buffer means, print command information input from an operation system to the printer driver;
a second storing step of storing, in a memory, one page of intermediate language data generated based on the print command information stored in said first storing step;
and
a command decreasing step of, when the one page of intermediate language data is stored in said second storing step, if an attribute of the print command information which has already been stored in said first storing step is identical to that of newly input print command information, generating new print command information based on the already stored print command information and the newly input print command information and allowing one page of intermediate language data generated based on the generated information to be stored in said memory;
and
generating a print job for a printer based on the one page of intermediate language data stored in the memory,
wherein a number of commands of the new print command information generated in the command decreasing step is smaller than a total number of commands of the already stored print command information and the newly input print command information.
