ABSTRACT:
A scanner/printer system for smoothing the edges of text or line art is described having a copyboard for an image original, a CCD, a PCI bus, edge smooth software and a laser printer. The edge smooth software adds variable size fill-in patterns of pixels to the image data scanned by the CCD at low resolution to smooth the edges of text or line art prior to printing at high resolution.
