The MX922 features a scan resolution of up to 2400 x 4800 dpi optical.
You can enter a value within the range of 25 dpi to 19200 dpi. You can enter a value within the range of 25 dpi to 600 dpi.
For example, HP, one of the largest printer manufacturers, specifies the value 4,800 x 1,200 dpi for its DeskJet 4120. This states that the multifunction device can print 4,800 dots in a row and 1,200 dots from top to bottom. This means it prints a total of 5,760,000 dots per square inch.

For printing, the recommended resolution for all images and art files is 300 dpi. The offset press cannot accurately reproduce resolutions above 300, so it is the industry standard.
The industry standard for quality photographs and image is typically 300dpi. For businesses, producing an external document like a brochure, a booklet, or a flyer requires 300dpi. You might be able to get away with 250dpi if you are less concerned with the quality and resolution of the printing.
With the printer powered on, press the Menu button. Use the arrows to select Setup, then press the OK button. Use the arrows to select Device settings, then press the OK button. Use the arrows to select Reset setting, then press the OK button.
Generally, 300dpi is a high-res print and 1200 dpi is ultra high-res beyond what is often used even for extremely detailed fine art applications.
True 1200 dpi provides high quality, precise printing, but requires more memory and slows the printing speed. Class 1200 dpi is actually a slightly lower resolution, however it provides high quality printing results on par with 1200 dpi with the Enh.MG and RITech functions.
500 dpi is excessively High resolution for printing photos. First do any suitable crop that will match the paper aspect. Then resampling smaller to 3000×2400 pixels (7.2 megapixels) will fit 10×8 inch paper at 300 dpi.
For most documents, 300 dpi is sufficient enough to be of good legibility and to provide adequate OCR results. In some cases 200 dpi may be adequate for simply retaining a print copy of a document. Scans at 400 and 600 dpi will results in slower scan speeds as the scanner detect fine details in your document.
Recommended minimum resolution for printing is 300 dpi; computer monitors generally have a display setting of 72 dpi or 96 dpi. If we indicate that some of your images have low resolution, they may not look bad on your monitor but will likely print blurry or jagged.
Up to 9600 x 2400 dpi (dots per inch) color resolution

High resolution for producing incredible quality and detail in documents and photos. Up to 600 x 600 dpi when printing black only.

For the average photographer, 1200 dpi is excellent. These specs are within reach of most printers on the market. When a printer prints above 1200 dpi, it`s nearly impossible to see any difference in the prints.
Up to 9600 x 2400 dpi (dots per inch) color resolution

High resolution for producing incredible quality and detail in documents and photos. Up to 600 x 600 dpi when printing black only.

This means that the more dots per inch (dpi), the higher the print resolution. For example, a 300 dpi printer can print 300 dots per inch of page space, whereas a 600 dpi printer can print double that amount, creating a much higher quality print.
Print Quality: A 1200 DPI printer can produce more detailed and sharper prints than a 600 DPI printer because it can place twice as many dots per inch. This increased resolution leads to smoother gradients, finer details, and better overall print quality.
Extraordinary Resolution: 9600 x 2400 maximum color dpi produces incredible quality and detail in both your business documents and photos.
