10–32 TroubleshootingGraphics Ap-pear Coarse inGDI ModeGDI graphics quality differs by application, becausedifferent applications may use Windows graphicscommands differently. If you are not satisfied withthe quality of your output in GDI mode for a particu-lar application program and file, switch to PCLmode.Text AppearsJagged or LowResolution inGDI ModeYou may have old system fonts embedded in yourdocument. Although Windows 3.1 has a minimumof 14 TrueType fonts, it also includes some fontscreated specifically for screen display. These areincluded to be compatible with older versions ofWindows.System fonts typically have lower resolution thanprinter fonts. Two system font typefaces that appearfrequently are MS Serif and MS Sans, which corre-spond roughly to the TrueType fonts Times NewRoman and Arial. Because GDI takes a WYSIWYPapproach (what you see is what you print), andbecause these fonts are fixed at a particular resolu-tion, they will have a jagged appearance on youroutput.One solution is to edit your document and replacethe undesired fonts. Another is to switch to PCLmode, which will substitute another font when youprint.A third approach involves telling Windows to useonly TrueType fonts:1. Switch to the Program Manager screen.2. Find the Main group, and double-click on theControl Panel icon.3. Double-click on the Fonts icon.
