Avoid Error
When printing complicated data (data which includes a lot of
words or graphics), a page error may occur because the printing
speed is faster than the image processing speed. To avoid the page
error, set the Avoid Error to On.
Note:
When this setting is On, the printing time may be long. When you do
not print complicated data, set this setting to Off (default).
Dot Correction
This setting is relevant to 1200 dpi printing only. When set to On,
the printing pattern of 1-dot lines is automatically corrected to
improve appearance.
Note:
When the Print Mode in the printer driver is set to CRT, this setting is
not available.
