Printing - Going Into List Files Interrupts |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Symptoms: When sending a document to the printer, if the customer goes into List Files, the print job stops temporarily and another user's document prints in the middle of the customer's print job. They are using a switch box (Model MP401B - Compu Cable), and the customer is aware that switch boxes are not directly supported. Solutions: Development explained that WordPerfect prints in the background, and the printing process is a low priority process. This means that WP only prints when nothing else is happening (i.e., between keystrokes when WP is waiting for a key). WP does this so that all other operations can occur at maximum speed. Going into List Files, particularly if there are many files in the directory, can take a few seconds. If the switch box is totally dependent on timing, then there is nothing that WP can do. WP will not slow down List Files or any of the many other features that take some time to execute, just so that dumb switch boxes can work (the term "dumb" is not a derogatory. It is a technical term that refers to the fact that the box does not monitor the data stream and so it does not detect the end of a print job). Using a software print buffer (spooler) might help keep the stream to the printer more consistent, but these often consume memory.
