Cool Tools: Cobra Ink System. Kevin writes –
After much research and trial and error I found that the easiest cheapest method of printing is a continuous ink supply built into a printer. Once you are set up you can buy ink inexpensively by the pint, quart or gallon. A pint bottle of ink will cost no more than one of those itty bitty 1 oz. cartridges and will last hundreds of times as long.
A continuous ink system runs tubes from the refillable ink containers into the moving ink head in the printer. The printer operates normally. You simply refill the outside container with bulk ink and keep printing on the same originally installed cartridges. There are a number of outfits that will sell you a kit to do this yourself. I’ve heard of occasional satisfaction with this method. But installing this gear can get really messy and hairy. You are on your own if it does not work correctly. And some printer models are easier to retrofit than others.
This is an interesting way to save money on ink, we use a Xerox solid ink printer but this is something we might consider down the road.
