DPI Resolution (Print Quality)

---

The DPI (dot per inch, resolution) defines the number of pixels that can fit into an inch of space. The higher the DPI, the better the image quality.

Zan Image Printer provides ten predefined DPI groups during the installation.

Group	DPI resolutions
Group1	50 x 50, 60 x 60, 75 x 75, 100 x 100, 120 x 120, 150 x 150, 200 x 100, 200 x 200, 240 x 240, 300 x 300, 360 x 360, 400 x 400, 600 x 600, 720 x 720, 1200 x 1200, 2400 x 2400
Group2	204 x 98, 204 x 196
Group3	72 x 72, 96 x 96, 144 x 144, 288 x 144, 288 x 288
Group4	240 x 144, 240 x 288
Group5	240 x 216
Group6	800 x 600, 1200 x 600, 2400 x 600
Group7	203 x 305
Group8	600 x 540
Group9	254 x 254
Group10	250 x 250, 500 x 500

Like paper size, the memory required to process an image is directly proportional to the selected DPI resolution.
The higher the DPI, the larger the image file size and the slower the printing speed. So it is advisable to
select the lowest possible dpi that still gives good image quality to produce desired image size.

Which DPI resolution is right for you?
If you have decided to create printer-friendly versions of images, choose a DPI resolution that is the same as the DPI of the printer that will be used. For example, if printing to a 300 DPI printer, use 300 DPI.

If you are creating images for on-screen viewing or web presentation, you don't need the extra data in the image that is required for printing. A lower setting of 100 x 100 DPI should produce acceptable results.
