Using a Macro to define a print area and send to default printer

Hi, I am new the forum and a novice at Excel Macros and viertually no VBA experience.
I was hoping someone could help me get started with a specific task I am working on.
I want to create a button on an existing Excel sheet that defines a print area and sends to the default printer.
This would include columns a-l and rows 1-x. Row X being the last row that has an data in column A.
I don't even know how to create the associated button for this Macro...assuming a macro can be written to accomplish this task.

Any help or examples are appreciated.

Thank you,

Tad
