WordPerfect® 5.1 for DOS

Problem

Solutions: A customer using the QMS PS 800 ii printer with LPT1 as the port was able to print from DOS just fine. But when trying to print from WordPerfect he would receive a "Printer Not Accepting Characters" message in printer control. After the customer changed the printer port using option 8 for Other and typing in "LPT1" as the port print continued as normal. Setting the printer port to LPT1 through the Other option uses the DOS port which uses less pins (less error checking) than does WP's ports.

The whole problem seemed to be based on the point that when the customer had placed a breakout box** on the cable between the computer and the printer and the printer's output interface for the paper out was high. (This means that the printer thought it was always out of paper.) DOS doesn't check for this but WP does. The customer had the printer exchanged for another of its kind and it then worked using WP's port.

**A breakout box is a device used for checking the lines. Some are designed for Serial devices, others for parallel devices.
