I cannot get my HP officejet 7000 to work with my Macbook Pro?

• OS X Mountain Lion and OS X Lion systems will have the necessary printing software already installed, or will automatically download and install software when the printer is connected or configured. Do not install software that came with the printer as it may be out of date, and do not connect the printer to your Mac yet. Follow the instructions that came with the printer to unpack, install ink or toner, and insert paper. Finally, use the instructions in this article to connect the printer to your Mac.
• Make sure the printer model is listed in Printer and scanner software, which is a comprehensive list of all printer models that have compatible software for OS X Mountain Lion and OS X Lion.

I installed the HP Officejet 7000 and at first it worked ok however on rebooting my Macbook Pro I can no longer connect to the printer? This has happened with 2 different HP Officejet 7000 printers. Does anyone have a solution?

Some external hardware drivers Apple doesn't have or the most recent updates, this looks like one of them.

Reinstall the software and/or contact HP for assistance.
