Canon LBP-8 A2 Shaded Boxes Lower Quality Tha |

WordPerfect® 5.1 for DOS
Problem
Symptoms: The customer is using a Canon LBP-8 A2 printer. In 5.0 using high quality graphics doing a shaded (10%) text box it looked good. In 5.1 you can see the dots. I don't know if it is the driver or the program. Solutions: I talked to Dave (the driver writer) on this one, and he said that the only real difference between the 5.0 driver and the 5.1 driver (as far as graphics is concerned) is that he has enabled support for rules/patterns in the 5.1 driver. I worked on an STR with the HP Series II that had similar side effects. When you print with regular raster ("bit-mapped") graphics, you can get finer shading than you normally get when printing rules (rectangular areas) with gray-shading PATTERNS. However, in most cases raster graphics requires sending a LOT more code than using rules. In short, try taking them into PTR, into their driver, down to Graphics, down to Rules and Shaded Boxes, and mark "Rules Not Supported". This should default their graphics printing back to the method used in 5.0. Don't forget to remind them that it may increase the complexity (or amount of data) sent to the printer. Of course, if they don't do anything worse than medium-sized text boxes, they should be okay. (If they start getting "Out of Memory" errors at the printer, have them switch Graphics methods back to the default one in the 5.1 driver.) |
