Most of the printers in the market today use multiple ink cartridges to print pictures or documents. Once an ink cartridge runs out, often, the printer won't print until you replace the empty cartridge with a new one. However, there is a workaround to continue printing with only one full ink cartridge left in the printer. You can do this by changing the printer "Property" options before printing. Refer to the blog above for more information on printing with only one ink cartridge for Epson, HP, and Canon printers.
