You do not want to run out of ink in the middle of an important project. To help you monitor how much ink you have left, HP bundled an ink monitoring feature along with its basic printer drivers and tools. With these tools, you can keep tabs on ink levels in the HP Desktop F300 series printers, and purchase replacements before running out unexpectedly.
