WordPerfect® 5.1 for DOS

Problem

Symptoms: The customer has an HP DeskJet printer with a 128K RAM cartridge. He has loaded Bitstream 3.0 for WordPerfect 5.0 and 5.1 and created fonts for the printer. The three fonts he is trying to access are Bits Charter Roman 10 point, 12 point, and 14 point. WordPerfect believes that the printer has enough memory to handle all three of these fonts. When he initialized the printer, only two of the three fonts are actually stored in the printer. He can have any combination of two fonts but not all three at the same time. Solutions: The DeskJet (Regular) has a limitation in how it handles the 128K cartridge. The printer has to accept the data in 64K chunks. For example, some fonts (like the Helvetica 12 point) use the biggest symbol set and must be broken down into two parts. If you have enough fonts marked in WordPerfect that almost all of the 128K is used and if toward the end of the first 64K block you try to download one of these large fonts, there may not be enough memory in that first 64K block to hold both parts of the font. If this is the case, the font will be ejected or not useable. The bottom line is that if you have a font that is broken into two parts (like the Helvetica 12 point with the biggest symbol set), there must be enough room in the 64K block of memory for both parts of the font. To help get around this problem, you would download the biggest fonts first. However, WordPerfect does not specifically download fonts in a size order. WordPerfect downloads the fonts in the order in which they were actually added to the printer's .ALL file. This problem only exists on the regular DeskJet since the DeskJet+ and DeskJet 500 look at the memory as one continuous block of memory instead of in 64K chunks like the DeskJet (Regular).
