Problem

Symptoms: When printing a DrawPerfect text file imported into WordPerfect with graphics quality set to high, the graphic loses the spaces between the graphic lines when using the new HP LaserJet IIISi (04/21/91) driver. It prints fine in medium quality. It also prints fine out of DrawPerfect using the HP LaserJet III driver. Solutions: On the 11/09/90 release, WordPerfect added an enhancement to the printer driver: Graphics Null Data. Extra checking was added in the driver to prevent null graphics data from being sent, reducing the amount of data sent and increasing printing speed in some instances. Null data is the white space that you see when printing a graphic. There is no problem if the computer has enough memory to rasterize the graphic that includes the line(s) of null data in memory without swapping to disk. This is why you didn't have the problem when printing the graphic in medium because it cuts the size of the graphic data in half. It will also work fine if there isn't a line of null graphic data, even if there is not enough memory to rasterize the graphic in memory. In order to keep track of the vertical position, WP has to be able to pass the vertical position, even if it is swapping to disk to the printer definition. WordPerfect has no way of passing this vertical information to the printer driver. The only way to resolve this problem is to remove this enhancement. This will increase the amount of graphic data that the printer has to process, since the null data will now be sent down, and may decrease print speed. The way to correct the graphic position printing problem is: 1. Retrieve in the .ALL file into the PTR Program and select the users HP printer (This problem is not specific to the HP III printer, but to all HPs and possibly compatibles) 2. Cursor to Graphics and press Enter on Bitmap Graphics 3. Press Enter on Monochrome Raster data format, and cursor to Set Graphics Data Transfer and press Enter 4. Delete the string in the expression box and type in: hpgraphtrans 5. Exit, save, and replace 6. Update in WP (Shift-F7, S, U) This problem was corrected in the 07/12/91 release of the printer drivers.
