ABSTRACT:
A printing media roll mounting mechanism including a frame defining a roll compartment for accommodating a printing media roll. First and second roll holders are mounted in the compartment in axial alignment substantially perpendicular to the web path for concurrent oppositely directed linear movement. The first and second roll holders are spring urged toward one another but can be moved apart to receive different width media rolls therebetween. When the first roll holder is moved outwardly, e.g., to the right, against the spring urging, the second roll holder will also move outwardly to the left. The two roll holders are spring urged toward each other to respectively engage opposite ends of a media roll core placed therebetween.
