My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
Follow these steps to make the New HP printer default printer in windows.
It will be the HP in the list that does not have the Green check mark, it may also have a (1) or (copy) in parenthesis,
In Windows 7 click Start, click Devices and Printers.
Right-click the printer you wish to use as your default printer and select 'Set as default printer.' Right-click the printer icon again to verify that the correct printer is now set as the default. When the menu opens, a check mark should appear next to 'Set as Default.'
3. If a right-click menu doesn't display the 'Set as default printer' option, double-click the printer icon to display the Print Queue. Click on Printer and select 'Set as default printer' from the menu. A check mark next to the menu item or printer icon indicates that the printer is now set as the default printer. You can change your default printer setting at any time.
Let me know if it works please.
