Years back we had two or three Apple Computers in the house. Apple makes a good computer but sometimes there is a problem finding interface software and equipment. You need to help me some, because I am long out date on Apple/Mac products.
Does your iMac have a USB port(s)? I believe that is how your computer communicates with your printer.
The old Legend required a serial port connection at the computer. That has changed with the Legend HCX. It comes with a communication cable, mini usb for the gps end and standard USB for the computer. I am recommending the Legend HCX based on your post. The transition to the upgrade Legend HCX will be quicker because you have been using the controls on your old Legend. For the lack of a better term I will use the word language. You already speak some Garmin and going to the Legend HCX shortens the learning curve.

The new unit comes with a USB cable in the box. You will need to buy one other item and that is a “Micro SD Card”.

On the same theme I would recommend the purchase of US Topo for Mac and Windows:
http://www.walmart.com/ip/MapSource-TOPO-U.S.-Mac-Windows-DVD-for-Garmin-GPS/10740713A few years back I sent a couple of Hotshot Crews to Eagle N64˚47.265 W141˚47.265. After getting the dispatch done I popped open my laptop and consulted Map Source Topo 2008 for a look at the terrain around Eagle. A good tool and a check of the Wal Mart site surprised me with the lowest price I have seen for the software.
The following is a list of software support for Mac OS.

I do not trust the lanyard that comes with the Garmin Units. A friend replaced his with a heavy duty one designed for skiers. I carry my gps units in a camera case with a sturdy strap and belt loop. The lanyard is fastened to the strap on the camera case, and the case is zipped closed.
