I can't connect or print wireless

Question

I have the hp photosmart c4780 and I used the USB wire to connect it to my computer after installing the software off the internet as I lost the software it originally came with. So with that being said, on my little Eee asus netbook windows 7 I can print with the printer when it's connected via USB only! Also I use my printer mainly for printing coupons or documents, and if anyone's familiar with <a href="http://www.coupons.com" target="_blank">www.coupons.com</a> then you'll know they have an app for most all tablets and smart phones and so I downloaded it on both my ipad 2nd generation and my iPad mini, and I was able to print coupons wirelessly via the coupons app only, not via the <a href="http://www.coupons.com" target="_blank">www.coupons.com</a> through my safari browser. So I'm just not sure why I can't get it to connect wirelessly, when I went through the installation and set up process I went through the option of switching to wireless rather than USB and I thought it went smoothly but any other way I try to print from my computers or iPads it will say that the printer isn't discovered. I've also made an account with th hp connect, I've got the eprint hp app on both iPads and I'm having no luck! Also, my printer is just now I'm noticing also, offline i dont know how that happened, but when I printed the wireless network test report along the top it's saying that &quot; MAC ADDRESS FILTERING MAY BE ENABLED ON YOUR WIRELESS ROUTER, THIS CANT PREVENT YOUR PRINTER FRIM CONNECTING TO YOUR WIRELESS NETOWRK DURING SETUP. IF YOU DO HAVE MAC ADDRESS FILTERING ENABLED AND WOULD LIKE TO KEEP IT ENABLED YOU MUST ADD THE MAC ADDRESS OF YOUR PRINTER TO THE LIST OF PERMITTED DECICES FOR YOUR WIRELESS ROUTER BEFORE CONTINUING. THE MAC ADDRESS FOR YOUR PRINTER CAN BE FOUND ON THIS TEST REPORT.***&quot;<br>And I can see below on the print out where my MAC address is, however this isn't helpful because I don't know what MAC address filtering means nor if it's bad or good, or how I can change it accordingly. And in the diagnostics summary below it says NO FILTERING: FAIL<br>I'm unsure as to what that means?<br>So if anyone can help me I'd so greatly appreciate it,<br>I also tried to find that claim code that I was supposed to be able to find when i do the print out on my printer and I can't see it on the test report or the configuration page.<br>So, so far I've just reset the printer itself to default settings. And from here...well...as you can see..<br>I NEED HELP!?!?<br>Please and thank you!

Hi HBS4026,
Welcome to the HP Support Forums.  I think that the root issue you are experiencing is the printer is not connected to your wireless network, and as a result you are running into several issues.
wikiHow’s How to Find the MAC Address of Your Computer has a nice and non-techie description of what a MAC address is and how to find it.  By turning on the MAC filtering for your router, is a way of telling your router that only the devices with an approved MAC address will be allowed to connect to your network. 
Most customers with home wireless networks don’t use this feature, as it can take more time to maintain than a person would like to give.  It requires that you add/maintain the MAC address of any device that will be connecting your to network, including, but not limited to, iPads, tablets, Smartphones, iPhones, computers, laptops, etc.
Please start by turning the router off. If your router doesn’t have an on/off switch, please disconnect the power cord.  After waiting a full 60 seconds please turn the power back on (or plug the power cord back in).  Hopefully the network test report will give us a pass on No Filtering.
If MAC filtering is turned on (I suspect it is on) and you don’t want to use this feature, please contact the manufacturer of your router on how to turn this off.    I do think this is the root of your connectivity issues.  
Once you have confirmed that MAC filtering is off  we should be able to get everything working wirelessly by following the information below.  
Let’s start with your Windows 7 laptop.  I’ve included the How Do I Find the Best Windows 7 or Windows 8 Driver for My Printer? document.  It will walk you through downloading HP’s Printer Install Wizard.  This will also help you connect the printer to your wireless network while ensuring you have the right driver for your printer.
Once you’re printing from your laptop wirelessly, please try test printing something from the notes app on your iPad.  If your router supports Bonjour, the communication method for Apple’s AirPrint feature, you should have no problems printing.  If you are unsure, I have included a post by Shirlzz1 that will walk you through downloading an app to check.
As for printing from coupons.com using the Safari browser on your iPad it comes down that the iPad is considered a mobile device requiring the app as an interface. 
I think I’ve addressed everything that is plaguing you.  If I haven’t please let me know.  In addition, if anything goes askew while doing the above, please let me know at which step things went wonky and the contents of any error messages and where they were displayed.
