The present invention provides to a transport package for lifting and positioning a wide format media roll into or out of a printing system, comprising a deformable support body for supporting a bottom side of a media roll in a stabilized manner, a releasable securing member for releasably securing a first end of the support body to an attachment region of the support body, such that the support body forms a substantially closed loop around the media roll, and at least one carrying member provided at a second end of the support body and arranged for engaging lifting means for lifting the media roll. Additionally, a media roll assembly and a method for loading a media roll into a printing system are provided.

Rolling assembly for packaging web material in a roll having a base member with concave arcuate feed surface defining an upwardly-extending ramp, first intermediate member movably coupled to base member, and top member moveably coupled to at least one of base member or first intermediate member, top member having a concave arcuate pressure surface facing feed surface of base member. The base member, first intermediate member and top member collectively forming an iris with a feed space, the iris moveable between a first condition and a second condition, and configured to receive web material along the feed surface and direct the web material upwardly toward the top member to form a roll within the feed space, the iris moving toward a second condition as the roll of web material increases in cross dimension against the pressure surface of the top member.

A printing apparatus includes a roll paper compartment 15 having a first placement surface 27 on which an outer peripheral surface Ra of a roll paper R around which a recording paper P is wound is placed and accommodating the roll paper R, a thermal head 67 performing printing on the recording paper P pulled out from the roll paper R accommodated in the roll paper compartment 15, a first projecting/retracting portion 77 provided to be configured to project from or retract into the first placement surface 27, pressed by the roll paper R of which the outer peripheral surface Ra is placed on the first placement surface 27 and retracting into the first placement surface 27 when a diameter of the roll paper R is larger than a predetermined diameter, and released from the pressure by the roll paper R and protruding from the first placement surface 27 when the diameter of the roll paper R is smaller than the predetermined diameter, and a detection section detecting projection and retraction of the first projecting/retracting portion 77.
