A method and apparatus are provided for printing a color computer screen display on a monochrome printer by establishing for the screen display a print filter including a set of filter blocks for controlling the printing of the screen display, wherein each filter block designates a filter realm area on the screen in which the filter block is active and a filter color acted on by the filter block and a filter type instructing the printer to either print or not print pixels which lie within the realm area of the block and have a color which matches the filter color of the block. Plural print filters can be established for a screen display or display components thereof and each print filter is enabled when the associated screen display or display component is displayed on the screen. For any portion of a screen display or display component which lies within overlapping realm areas of different print filters, the last-enabled print filter governs the printing. The system can automatically change a print filter in response to a change in the screen display or display component with which the filter is associated.
