Epson Compatible Printers - Vertical Line Dra |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Symptoms: The customer has an Epson LQ-2550 printer. The customer created a vertical lines using Line Draw. When the file is printed, the lines print jagged. Solutions: The problem is caused by a rounding error. The pitch that WordPerfect thinks that the printer is using and the pitch that the printer is actually using are two different pitches. This situation will occur in several instances. There are two ways that the printer can move horizontally. 1. A character is printed and the printer automatically moves to the next horizontal position because of the font and pitch being used. OR 2. The printer may move horizontally when WordPerfect sends a horizontal position code that would cause the printer to move to a specific horizontal position. a. In this case, both types of horizontal motion are being used. One is used when either text runs right up to the edge of the line draw, or where a horizontal line intersects the vertical line or the printer is automatically moving to print the next character which is line draw. b. On the lines that there is nothing right up against the line draw, WordPerfect is sending a horizontal position. The printer uses 360/ths motion, so WordPerfect cannot send exactly 1/17th of an inch since because it is not divisible by 360. Wordperfect uses 17.14 characters per inch, and the difference between the 17 which the printer is printing in, and the 17.14 that WordPerfect is using is what causes the problem. The following steps in PTR program correct the problem: 1. Enter the PTR program, retrieve the .PRS file, and press Enter on the printer name 2. Move the cursor to Font and press Enter 3. Perform the following on each of the 17cpi fonts -Move to the Font and press Enter -Move to Character Map and press Enter -Move to the character map for Line Draw and press Enter. Move to the Line Draw character set (character set 3), and for each of the vertical Line Draw characters, type the word Reposition before the value for the character. 4. Exit the PTR program and save the modified .PRS file The changes shown above will not be changed in the master printer driver because the print speed will decrease due to the changes. This problem may occur for any printer having this problem with the 17cpi font that is Epson compatible; this would include, Panasonic, Fujitsu, Okidata, and Star.
