The ink for our printers is rather expensive, but there are different ways to save money. This could be done by changing the settings prior to your next printing job. For example, if you print black and white, set so before printing. If you are printing something, which is not for presentation and just as a reference, the printing job could be set to low quality to save on ink. Web Worker Daily ran through some instructions for printing settings (here), including other ideas to reduce costs.
If you have any suggestions, please mention them in the comments for all to read.
