Generating and storing a printed representation of a document on a local computer upon printing

A computer program product comprising a non-transitory machine-readable medium including a computer readable program, wherein the computer readable program when executed on a computer causes the computer to:

• intercept a command to print a page intended for a printer graphics dynamically linked library;
• create a printer device context for a target printer device, the printer device context having an associated primary surface, the primary surface used to draw a printed representation of the page to the target printer device;
• create a memory buffer on a local computer and associating the memory buffer with the printer device context as a secondary surface, the secondary surface used to draw the printed representation of the page to the local computer;
• perform the command on the target printer device and the memory buffer to output the printed representation of the page on the primary surface associated with the target printer device and on the secondary surface associated with the memory buffer;
• extract features from the printed representation of the page on the secondary surface by applying a transformation rule to a portion of the printed representation of the page and parsing the portion of the printed representation to capture coordinates corresponding to the features;
• and store, on the local computer, contents of the memory buffer including a raster image of the printed representation of the page along with the extracted features.

A system comprising:

• one or more processors;
• a printer driver stored in a memory and executable by the one or more processors for intercepting a command to print a page intended for a printer graphics dynamically linked library, creating a printer device context for a target printer device, the printer device context having an associated primary surface, the primary surface used to draw a printed representation of the page to the target printer device, creating a memory buffer on a local computer and associating the memory buffer with the printer device context as a secondary surface, the secondary surface used to draw the printed representation of the page to the local computer, performing the command on the target printer device and the memory buffer to output the printed representation of the page on the primary surface associated with the target printer device and on the secondary surface associated with the memory buffer, and extracting features from the printed representation of the page on the secondary surface by applying a transformation rule to a portion of the printed representation and parsing the portion of the printed representation to capture coordinates corresponding to the features;
• and a storage module stored in the memory and executable by the one or more processors, the storage module coupled to the printer driver and for storing, on the local computer, contents of the memory buffer including a raster image of the printed representation of the page along with the extracted features.
