This could be re-written: "Unlike PCL, PostScript is device independent. that the print quality is at the mercy of the PostScript interpreter implemented inside the printer. If they have done a good job, graphic objects will be consistent and in some cases of higher quality than PCL, but can equally be terrible if the firmware developer has done a shoddy job." Really it's just moving the problem. If the PostScript interpreter in the printer does a poor job of generating the raster image to be printed, it's going to look crap no matter what. That does mean that PCL printers do have an up-side in that you can at least control the PostScript→PCL end of the equation, and if the PCL is well documented, it is theoretically possible to get good quality output. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.
