Printer job depends
The quality of the print job depends not only on the printer but also on the ink or toner cartridge.
Ink cartridges contain liquid and are used by inkjet printers, while toner cartridges contain powder and are used by laser printers. The ink in an ink cartridge can either be dye-based or pigment-based, depending on which cartridge you have. If your printer uses ink instead of toner, it is possible that the ink has dried and needs to be replaced.

Did you know that the type of paper you use also influences the print quality?
Ensure that you’re using the right type of paper for printing, whether coated or uncoated. Uncoated papers are printing papers which are non-reflective. Whereas coated papers have a dull/matte or gloss finish.
If the paper is not an issue, the toner could be the problem. Try taking the toner out, shake it slightly a couple of times and place it back in the printer. Avoid touching the toner roll or it can leave fingerprints. This should help resolve the issue.
