Mac OS X Lion compatibility with HP officejet K80

The 1018 is not supported by HP with the Mac OS Mountain Lion. I found this on an HP forum and it worked for someone else. You could try this:

Hi,
Thank you for posting,
Unfortunately, HP laserjet 1018 is not suported in Mac OS X 10.8 Mountain Lion. How evere you can use the builtin drivers that goes along with the operating system and select teh driver of another printer and check.

The Brother HL-3095CW is a color laser printer that is not natively compatible with Mac OS X Lion.
However, there are a few ways to get the printer to work with your Mac:

• Download and install the Brother printer driver for Mac OS X Lion from the Brother website.
• Use the built-in AirPrint feature in Mac OS X Lion to print wirelessly to the Brother HL-3095CW.
• Use a third-party software such as Gutenprint or CUPS to add support for the printer to your Mac.
• Use a print server to connect the printer to your network and make it available to your Mac.

It's important to note that this printer was released in 2009 and Brother's support for this device and Mac Lion will be limited. It's recommended to check Brother's website to see if the printer model is compatible with the latest Mac OS version and the support for the printer model.
If you continue to have issues with getting the Brother HL-3095CW to work with your Mac, it would be best to contact Brother technical support for further assistance.

I wonder whether the Word Doc SDK I am testing these days can help with the related programs?

You need to re install your windows operating system. You can use OSx on IBM compatible systems but then you will face problems with leagality. Apple don't want you to run their OS on something that isn't made by them. Even though all of the parts are the same (just cheaper) If you are lucky you may have a restore partition on your system, to access this you need to restart and press "F8" then pick "restore to default(or factory)" Hope you are lucky.

From HP driver site,

"Many drivers for HP products are built into the Mac OS X operating systems, or are available through Apple Updates. You can use these drivers by simply connecting the product and adding the product to the printer list. If you installed the product in this way, you received the print driver, fax driver (if applicable), and the HP Utility print management software"
