My hp officejet 6500 E709n will no longer print wireless after additional printer added.

Macbook using os 10.5.8, hp officejet 6500 E709n stopped printing wireless after installing addtional printer.  It is saying that my printer is offline and there is a connectivity issue.  The printer will print when connected direct to macbook, also will print wireless from another laptop.  Some of the things I have tried, deleting all printers from sys. pref printers and faxes then connect printer to macbook where it then shows back up sys. pref printers and faxes(should I be reinstalling my driver at this point?) Powering down router, printer and macbook then restarting.  The printer had been printing wireless for over a year and when the additional printer was added a few days ago it deleted the hp printer(I believe the system was reset deleting the hp printer).  As you can see I need some assistance, thanks.

Get the latest software for your BOTH of your printers from the "Support & Drivers" link at the top of this page.

Choose the appropriate "Full Feature" software for each one.

Install the software for the oldest printer first.  Once it is done, restart your Mac, then install the newer printer's software.
