Google-chrome – How to save on ink when printing this map

University of Wisconsin Green Bay changed to Century Gothic, which they claim uses roughly 30 percent less ink when printed on paper. Here's an article on the University change.

Folks at Ecofont say theirs saves more. Looks like a bit of a debate but ongoing research might find a winner.

Here is an EcoFont comparison with other well known fonts.

Here are Arial and EcoFont compared:

Hi,

Unfortunately it is not possible to print using the black and white while any of the ink cartridges are empty.

Using the Black ink only possible while there is color ink as well.

While the color ink is not required for prinitng purposes, it do required for ,maintnance operations of the device.

As the device contain an internal printhead (IIC system), lack of color ink will damage the printing system shortly. Therefore the device will not be functional when there is no ink in order to avoid damaging the system.

For users who wish to print using just black ink (despite the reduced print quality), many HP printers offer options. For example, a driver colour setting (by selecting "print in greyscale with the black cartridge only" in printing preferences) specifies printing using only black ink. In addition, many IPH printers can operate in "reserve mode", which allows the user to continue to print with just the black cartridge when the colour cartridge is removed or not installed.In HP IIC systems, all supplies are required to be installed in the printer for the printer to function
