To change a type disc without moving or removing a ribbon cartridge while yet permitting the location of a ribbon cartridge closer to the printing point of a type disc printer, there is provided mechanism to allow pivoting movement of a hammer assembly relative to an independently pivoted type disc drive assembly thereby to change their relative orientation, after which continued movement of the hammer assembly carries the pivotally mounted type disc drive assembly to a type disc change position. The change in orientation of the hammer assembly relative to the type disc drive assembly, before pivoting the type disc assembly, allows greater arcuate movement to type disc change position without interference between the hammer assembly and the ribbon cartridge.
