     I believe you're referring to the lasermatrix driver.  It's up on Qlink,
so you can look for it there.  It comes with a menu-driven editor that
guides the user through the process of adapting the driver to his or her
printer.
     It doesn't quite exactly work as Elezar describes.  Lasermatrix
uses the high resolution graphics mode of many printers to smooth out
graphics.  It makes output from geoWrite in particular look really
sharp.  If your printer doesn't have a high-resolution mode, you can't
use lasermatrix.  Also, you can't use lasermatrix to overcome GEOS
natural preference for 80dpi.  It doesn't make anything wider (or
narrower), just smoother.  Nevertheless, it's an impressive driver.
