I don't see a LaserJet cp 1215 listed here -> http://support.apple.com/kb/HT3669#HP - but you may want to take a look yourself. It may be that your printer isn't supported by OS X.
If you do see your printer listed, you can download the drivers here -> http://support.apple.com/kb/DL907.
If you don't see your printer listed, you may be able to contact HP and see if they've any drivers compatible with OS X. Failing that, you may be able to use a "Guten-Print" driver -> http://gimp-print.sourceforge.net/MacOSX.php.
