Resolution in
GDI Mode
GDI graphics quality differs by application, because
different applications may use Windows graphics
commands differently. If you are not satisfied with
the quality of your output in GDI mode for a particu-
lar application program and file, switch to PCL
mode.
You may have old system fonts embedded in your
document. Although Windows 3.1 has a minimum
of 14 TrueType fonts, it also includes some fonts
created specifically for screen display. These are
included to be compatible with older versions of
Windows.
System fonts typically have lower resolution than
printer fonts. Two system font typefaces that appear
frequently are MS Serif and MS Sans, which corre-
spond roughly to the TrueType fonts Times New
Roman and Arial. Because GDI takes a WYSIWYP
approach (what you see is what you print), and
because these fonts are fixed at a particular resolu-
tion, they will have a jagged appearance on your
output.
One solution is to edit your document and replace
the undesired fonts. Another is to switch to PCL
mode, which will substitute another font when you
print.
A third approach involves telling Windows to use
only TrueType fonts:
1. Switch to the Program Manager screen.
2. Find the Main group, and double-click on the
Control Panel icon.
3. Double-click on the Fonts icon.
