Abstract
A printing apparatus comprises a platen, a dot impact print head (23) opposite to the platen, a mask plate (40) between the platen and the print head with a paper passage between the platen and the mask plate (40), and an ink ribbon (31) between the print head and the mask plate. Transport mechanisms are provided to move the mask plate (40) in a direction substantially perpendicular to said paper passage between a first position on the print head side and a second position on the platen side, the transport mechanisms being responsive to the position of the print head along the platen. In the first position of the mask plate a relatively wide gap between the platen and the mask plate enables easy paper insertion, while in the second position a relatively wide gap between the mask plate and the print head facilitates replacement of the ink ribbon without problems.
