ABSTRACT:
A web-feeding mechanism for a compact printer which can feed at least one web of paper at selectively variable feeding rates is provided. A pair of rotatably driven web feeding rollers is positioned on a first side of the web of paper to be fed, and cooperates with a pair of selectively displaceable idler rollers correspondingly positioned on the other side of the web. The respective feeding rollers are each capable of being driven at a different rotary speed. The respective idler rollers are selectively displaceable between a first position out of engagement with its associated web feeding roller, at which time web feeding by the feeding roller corresponding thereto is prevented, and a second position in engagement with the paper web and the web feeding roller corresponding thereto for feeding the web therebetween at the feeding rate of the feeding roller.
