Are they Long Beeps? Does the RED led light on the front show up? If there is no RED led light blinking, then the problem is your RAM. If there IS a RED led Light showing up, then the problem is your Power Supply.
This is just an off-chance thing. The three lights could indicate a failed or badly seated memory chip.
Turn the Mac off and remove the side. Remove the perspex panel and then remove the grey plastic panel containing the 2 large fans (it just pulls out towards you).
You now have access to the RAM sticks. Use the illustrations on the inside of the Aluminium door to identify the sticks and so that you can remove and re-seat them. Refit the fans and the perspex panel and see if the mac will start up. If not, you may have to try extra RAM (depending on how much you have installed). These macs have their RAM installed in matching pairs so if you have only 2 stick in your Mac then you need to get 2 more in order to eliminate the first 2.
Report back if that helps.
Sounds like a communication error somewhere between the printer and your hardware. You might need to update the driver. Go to the manufacture's website and put the model number of your printer in to get the latest driver. There might also be a driver specifically for your Mac there.
