As the inventor of the commercial calculator in 1912, Monroe has earned the trust of Fortune 500 companies, non-profit organizations and government agencies, including the likes of NASA. Even Hollywood has recognized the strength of the Monroe brand as its products have landed on major television networks and hit series including the show Madmen. Monroe customers commonly buy ribbon cartridges and paper rolls for their calculators at the same time. So, in an effort to make that process easier Monroe has created supply kits that include (6) P51 ribbon cartridges and (12) single-ply paper add rolls of their premium offerings. Monroe’s engineers have developed the best available universal twin-spool ribbons for calculators and spared no expense when designing a ribbon with the highest inking degree on the market while eliminating the risk of ink smudges. Monroe has even developed a true red ink that is extremely rich in color and used exclusively by Monroe, unlike the orange tint you see in watered down versions from other brands. To maintain the darkest print on their paper tape, users of Monroe products are suggested to change their ribbons after replacing 3 paper tape rolls. Monroe’s premium single-ply paper tapes are 2 ¼” x 150’ in size and are offered on an impressive 20 lb paper stock, the thickest in the industry created exclusively for Monroe. Those who know, choose Monroe.
