This hint is not strictly Macintosh, but it’s so good I have to write it up. Did you know you can get what they call a Continuous inking system (CIS) for most big name inkjet printers? It continually feeds the ink into the printer so you don’t have to change the cartridges! You can see the big containers of ink in the photo above – they sit next to the printer.

Here is a picture of the inkjet cartridges which replace the old inkjet cartridges. These new ones have little tubes running from the ink tans into them to deliver the ink.

I purchased mine from RIHAC in Melbourne, Australia. They have a good unit, with good instructions as well as good phone support, the sell the CIS system for about $150 and it comes with I think it was 100ml of ink per color. Installing the CIS system is about the same complexity as changing a pushbike tyre, or sewing a button on a shirt. If you can follow instructions, you should be able to install it OK. Mine’s been going about 2 years now with no problems at all.
