ABSTRACT:
A method and apparatus for producing a zoom system within a printer is disclosed where the zoom system is adapted to selectively enlarge or reduce an original image such that the enlarged or reduced image can be printed onto a recording medium. Further, the zoom system is adapted to selectively adjust an aspect ratio of the original image. The zoom system utilizes a phase lock loop to produce a pixel clock in a fast scan direction and a governing motor control to alter incremental movement of the recording medium in the slow scan direction, thus, individual pixel size can be manipulated by varying a frequency of the pixel clock to alter a width of the pixel projected onto the recording medium and by governing overlap of successive print lines, and repeating print lines if necessary, to alter a length of the pixel.
