This article describes a printer which does not require a power paper feed. A raster-scanning, semiconductor laser is used to print photosensitive paper as an operator physically pulls paper from the printer. Marks along one edge of the paper are detected to synchronize printing with paper movement. The arrangement can be used for small printing jobs, such as printing of customer receipt tapes in retail or grocery stores. Referring to Fig. 1, a strip of photosensitive paper 10 is gripped by an operator and pulled in the direction of arrow 12 when a printing job is to be performed. Printing is performed by intermittently energizing a semiconductor (solid-state) laser 14 under the control of a microprocessor 16.
