HP LaserJet Series II--Error 21 |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Symptoms: The customer is trying to print out character set 10 from CHARMAP.TST. His printer keeps giving "Error 21". He has 2.5MB in the printer. The size of the print to disk file is only 87K. Solutions: Error 21 (or "print overrun") is a complex data error, which in simpler terms means that the pages complexity (rules, vector graphics, or dense text) may exceed the printer's ability to create the image and keep pace with the engine printing process. You can get this on printing complex graphic information, and a paragraph of pure graphically created DRS characters is no exception. The higher the quality the more prone you will be to get this error. The HP LaserJet IIP is not likely to have the problem because the output of the paper is slower, nor will the HP LaserJet III have the problem, because it has a safety feature that can be set on its menu, called page protection, that reserves additional memory for the page image processing. This allows the printer to create the entire page image (in memory) before physically moving the paper through the printer. This process assures that the entire page will print. In order to use this feature, the printer must have at least 1 meg of additional optional memory. The HP LaserJet Series II does not have either ability, but you must instead either decrease the quality of the output, or the complexity of the page. By setting text quality to medium we were able to output the entire character map 10. Its quality actually looks better with normal text, but it is not quite as crisp. Your customer will probably be pleased at the output, and at this point he really has no other option. |
