The compact thermal printer PTMBL1A, PTMBL1E, featuring a easy-loading mechanism, is the industry's thinnest. Besides motor alignment, an even thinner design has been realized by using a plate spring for pressing paper to the thermal print head, instead of a coil spring. This level of compactness is the product of design, manufacturing and simulation technologies accumulated over the years through the development of compact printers. The printers are ideal for hand-held terminals like mobile POS terminals and PDAs. Horizontal models compatible with 58mm-wide paper are also available.
