HP Cartridges and Supplies
Hewlett Packard is the company that essentially started "Silicon Valley". They got their start in a Palo Alto CA garage way back in the 1930's. Founded by Bill Hewlett and Dave Packard, the company started out making the advanced tech of the time period (one of their first products was an audio oscillator, which the Walt Disney Company used in theaters showing their new film Fantasia. Yes, the HP ink cartridge was a long way off.)
