This behavior is probably generated by the fact that your printer's cartridges are low on ink. In order to fix this problem, this is the first thing that you need to check. If this is true, charging the cartridges should be the solution. If not, try downloading the latest version of the driver from the official website. Also, go to Start > Control Panel > Devices and Printers > right click on the printer > Properties and revert the settings to the default state. You should be able to improve the quality of the printed items.
