Abstract

Point-of-sale terminal devices normally contain a journal roll printer. The journal printer utilizes a roll of paper tape to print a chronological record of transactions at the terminal. Journal printers normally feed the roll media past the printing station in either one of two methods: 1) Fixed line spacing is produced at or near the print line with the take-up spool being overdriven through a slip clutch to provide a continuous tension on the take-up side. This method permits the full roll of paper to be taken up with consistent line spacing but requires an escapement at or near the print line to permit paper to pass. This involves a more complex paper loading path than is desired in some instances.
