Low friction traversing carriers for printers typically have the disadvantage of relatively high cost. If the cost of the carrier is low, then the user is confronted with inadequate or poor designs exhibiting position variations or misregistration due to clearance for free movement. Provided is a low cost carrier-trolley design which provides for low friction movement, compensates for dimensional variation of the all within the limits of the axial freedom of the rollers, and permits of zero clearance for positional accuracy while allowing for quiet operation.
