I have a problem with my HP Laser Jet 4L, using Fedora Core 3. It is not a postscript-printer, so I must use a driver (gimp-print 4.2.7) and ghostscript (7.07) with cups instead. But the quality is not nearly as good as it should be. Does anyone know how I get this PCL4-printer really working? When using the other drivers (for example hpijs etc.) the quality is even worse than now.
