Welcome to the HP support community.
This printer model is pretty old.]
Support and service options for this printer model is limited.
However, try the below steps to fix the issue.
Change print-quality settings for all print jobs
In the Windows system tray, click Start, select Settings, and then click Printers.
Right-click the device icon.
Click Properties (in Windows 2000, you can also click Printing Preferences).
Change the settings, and click OK.
If the issue persists, it is better to go for a newer printer model.
I hope that helps.
To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.
Cheers.
