■ Adjusting the resolution
It doesn't matter how high the resolution of printing data is, you cannot get better picture
quality than the resolution of the printer. A resolution of 600 dpi at printer sizes is
sufficient. If the resolution of print data is too high, print processing will take a large
amount of time, and the data size will also grow. Conversely, if the data resolution is too
low, you cannot achieve sufficient image quality.
Check the dimensions and resolution of print data using an image processing application,
and set the resolution to 300 dpi or 200 dpi.
■ Selecting a print mode according to the document content
Reports and presentation material based on text and simple diagrams and black and
white documents that do not use color do not need high image quality and can be printed
using normal gradation. By changing to the mode for these documents, high-speed
printing can be achieved. To print color photographs and complex illustrations clearly, data
is printed with a high level of gradation. By categorizing modes based on the data, data
can be printed more efficiently.
NOTE
For details on gradation, refer to "Specifying the Print Quality," on p. 4-56.
