The printer gives you two different print qualities: In data proces-
sing quality (UTL) a print speed of 260 characters per second (cps)
is reached, printing being bidirectional, i.e. one line from left to
right, the next line from right to left, etc. This quality is suitable in
particular for extensive lists and drafts.

Letter-quality (LQ), which reaches a speed of 87 cps, should be
used to create correspondence or documents. With this print quali-
ty the characters are printed in a high dot pattern resolution. This
enables the creation of attractive documents when using a word
processor.

These print qualities can be selected via the menu item Print Mode
or the control panel.
