Abstract: A method and apparatus for outputting an electronic document, in which separation pages are automatically interleaved between successively printed pages of the electronic document. In one embodiment, the invention provides a method of printing an electronic document on transparency film using a computer printer having at least two (2) paper source trays. The method may involving modifying an existing printer driver associated with the printer to cause the printer to print pages of the document on sheets of transparency film obtained from a first paper source tray, and to automatically interleave blank sheets obtained from a second paper source tray between successively printed pages. For example, an existing printer driver is modified by automatically generating a new computer printer driver based on an existing printer description file that is associated with the existing printer driver, to redefine pagination and paper source tray attributes of the description file.

Abstract: A printer filter including a companion script file and which filters a standard printer data stream to perform a user-specified print job. In particular, the filter is a computer program which may access other programs or data files, and which reads a standard printer data stream, transforms the input in accordance with instructions contained within the computer program, and then outputs the filtered or transformed information to the printer. The present invention also provides a graphical user interface to assist a user in operating the computer program. In particular, the graphical user interface includes a parent window having a display control which list a possible filters to be selected, along with a plurality of other display controls to assist the user in operating the computer program product.

Abstract: A system and method which allows a software engineer to easily modify a resource file for a graphical user interface (GUI). A conventional hard-coded resource file is converted into a parameterized resource file with a header file. The parameterized resource file includes parameters for certain properties which were previously hard-coded in the hard-coded resource file. Further, the header file provides values for the parameters. With such a structure and operation, by changing the parameter values in the header file the parameterized resource file can be changed, thereby making it significantly easier to modify resource files, and accordingly to modify the display on graphical user interfaces. More particularly, a data structure is achieved which defines a graphical user interface. The data structure includes a first file which defines a display of a plurality of controls of the graphical user interface.
