Other ways to improve print speed in Windows To improve printing speed, you can try the following: t Turn off the Print Manager in the Windows Control Panel. This avoids the extra step of sending the print file to the Print Manager and may increase your printing speed by as much as 25%, depending on the computer you are using. (See the next section for details.) t Add a permanent swap file in Windows. Under the 386 Enhanced icon in the Windows Control Panel, add or create a permanent swap file that is from 4 MB to 9 MB. The computer will be able to prepare the print file faster. See your Windows documentation for instructions. t Avoid screen-matched color. In the Printer Setup dialog box, choose Plain Paper and Color when printing color images. The screen matching feature takes longer to process in the computer because it requires special information. t Avoid diffusion halftones. In the Options dialog box, choose Diffusion only when printing final output or photographic images. Choosing Pattern1 or Pattern2 allows documents to print as much as 20% faster because the computer does not need to compute to "best possible position" for each dot. t Free up your memory. Use only one software program at a time and unload any screen saving utilities or programs stored in Windows background; this frees up more memory for Windows processing. t Use Black and White when possible. If you will be printing text in black ink only, choose Black and White rather than Grayscale. Print draft documents in Black and White rather than Color, or use high-speed mode when printing color. t Limit the number of colors on each page. The computer will need to calculate and transmit fewer dots. Too many colors can make the image confusing and less effective as well as cause the print speed to slow down. t Use primary colors when printing presentation graphics. Use black, cyan, yellow, magenta, blue, green, and red when possible. The computer will need to calculate and transfer fewer dots. t Use high speed (draft) modes. The printer will need to image fewer dots. 68 Using the Printer With Your Software Chapter 4
