Our products are safe replacements for Hewlett Packard toner cartridges, the largest market player established in California in 1939 by William Hewlett and Dave Packard, two friends freshly graduated from the Stanford University. The company opened its Polish office in 1991. Today it employs workers all over the world and, Naccording to studies, has the largest annual turnover comparing with other companies of this type. Even if it originally became known mainly for its calculators, today it is famous for its computer hardware: palmtops, displays, servers, printers, scanners and, first of all, PCs for households and small business. HP has an extensive product portfolio particularly for the latter segment. This is true of not hardware alone but also software for manufacturers, power utilities, entertainers, travel agencies, financiers, health care professionals, biology researchers, etc.
