Printing and Scanning issues

1) Why might I have trouble printing even after my printer is successfully connected to my wireless network?
Solution : There are several factors that could affect your ability to print to a wireless printer.

• Other electronic devices are interfering
  You could be experiencing wireless interference from other electronic devices such as microwave ovens or cordless phones, particularly if your cordless phone operates at 2.4Ghz.
• Firewall software is blocking access to devices on the network
  If you are using firewall software on your computer, it may be blocking your attempts to reach other devices on your network. Be sure that if you see pop-up dialogs from your firewall software related to HP programs, you choose to always allow these programs access.
  • Security software firewalls (examples are Symantec, ZoneAlarm and McAfee) can block the HP software from finding your printer over the network. If you find that the printer can be detected once the firewall is disabled, go tohttp://h10025.www1.hp.com/ewfrf/wc/siteHome?cc=us&lc=en and search for "Printer Not Found". The "Printer Not Found" documentation provides guidance on how to configure your firewall to prevent problems from happening once you enable the firewall again.
  • See firewall help for more information.
• Another wireless router is using the same default SSID as your wireless router
  If you are using the default wireless network name (SSID) provided by your wireless router or access point, you can have trouble if others in your area are using the same default name. When there are two or more wireless routers or access points broadcasting the same SSID, wireless devices within range that are configured to use that SSID will automatically associate with the one that has the strongest signal, even if the security settings are different. For instructions on how to access and modify your wireless router configuration settings, refer to your wireless router documentation or manufacturer. Below are other common reasons why you might not be able to use your printer over the network.
• The printer is not connected to the network
  If you haven't already done so, print a Wireless Network Test report from your printer's control panel to confirm the printer has connected successfully to your wireless network. If the printer is not connected, the Wireless Network Test report may identify a possible cause (for example MAC address filtering may be enabled on your wireless router) and provide instructions on what to do next. Verify that your printer has a valid IP address (example 192.168.0.5) and has connected to your network's name (SSID).
• Your computer is connected to a VPN (virtual private network)
  If your computer uses a VPN connection to access an outside secure network, you must first disconnect from the VPN in order to use the printer on your wireless network.
• The computer and printer are not on the same network
  The best way to check this is to open your web browser (for example Internet Explorer) and type the printer's IP address in the address box of the browser (for example, http://192.168.0.5) in order to access the printer's home page (also called an EWS or embedded web server). This web page comes directly from the printer;, and being able to open and view this page proves the computer and printer are connected to the same network.
• The wireless router is in an improper operating state
  Sometimes wireless routers can get into an improper operating state and restarting can help. To restart your wireless router, remove the power cord from the wireless router, wait 30 seconds and then plug the power cord back in.

2) How do I fix printing and scanning problems ?

Solution : If you upgraded from Windows Vista to Windows 7 since you installed HP software for your wireless printer, you may experience printing or scanning problems. HP has a special patch to apply to your HP software.

To download and install the Windows 7 patch:

1. In your web browser, go to http://h10025.www1.hp.com/ewfrf/wc/siteHome?cc=us&lc=en.
2. On the page that appears, under Step 1, select Download drivers and software (and firmware).
3. Under Step 2, enter your wireless printer model number, and click Go.
4. On the Select your operating system page, select your version of Windows 7.
5. On the Select software and drivers page, select HP Print Software Patch When Upgrading Vista to Windows 7.
6. Download and install the patch according to the installation software's instructions.

3) How do I fix printing and scanning problems using Mac OS X?

Solution : If you recently upgraded to Snow Leopard (10.6), Lion(10.7) or Mountain Lion (10.8), or installed software for your wireless printer from the CD in the printer box, you may have the wrong version of HP software installed on your Mac.

To properly install the correct software:

1. Open a Finder window and go to the Applications / Hewlett-Packard folder.
2. Open HP Uninstaller.
3. In the HP Uninstaller window, click Continue.
4. On the screen that appears, choose your printer.
5. Press and hold the control, option and command keys and click Uninstall.
   • A dialog appears, asking if you are sure you want to uninstall all HP software.
6. Click Continue.
7. From the Apple menu, choose Software Update.
8. From the Apple menu choose System Preferences.
9. In the System Preferences window, click Print & Fax or Print & Scan.
10. In the list of printers on the left side of the window, select the wireless printer in question and click the minus sign (-) at the bottom of the list
11. Click the plus sign (+) to re-add the printer.
12. In the Add Printer window, select your printer, and click Add.

If your wireless printer is already connected to your wireless router, you may not need HP software because Snow Leopard, Lion, and Mountain Lion have both print & scan drivers built-in.

To be sure you have the built-in drivers, download and install this package:http://support.apple.com/kb/DL907 .

If your wireless printer is not connected to your wireless router you may need the HP software. In your web browser, go to http://h10025.www1.hp.com/ewfrf/wc/siteHome?cc=us&lc=en.

1. Select Download drivers and software (and firmware).
2. Enter your wireless printer model number, and click Go.
3. On the Select your operating system page, click Mac OS X.
4. Next, click the software for your version of OS X.
5. Then, download and install the software according to the installation software's instructions.

If you still have trouble printing or scanning, deleting and re-adding your printer and/or resetting the printing system is often an effective solution:

1. From the Apple menu choose System Preferences.
2. In the System Preferences window, click Print & Fax or Print & Scan.
3. In the list of printers on the left side of the window, select the wireless printer in question and click the minus sign (-) at the bottom of the list.
4. Click the plus sign (+) to re-add the printer.
5. In the Add Printer window, select your printer, and click Add.

If you still have trouble communicating with the printer, repeat this process, replacing the third step with:
> Right (control) click anywhere in the printer list and choose Reset Printing System.
