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

If you recently upgraded your version of OS X, 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 or Printers & Scanners.

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 newer versions of OS X have both print & scan drivers built-in.

To be sure you have the built-in drivers, download and install this package:

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 or Printers & Scanners.

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 (or Control) click anywhere in the printer list and choose Reset Printing System.
