[57] ABSTRACT
A serial recording apparatus is disposed for recording onto a recording medium while moving relatively a recording head with a plurality of recording elements arranged and the recording medium in a main scan direction and a sub scan direction which are orthogonal to each other. The apparatus includes a receiving unit for receiving a recording signal, and a recording controller means for enabling the recording head to record in one-way or two-way movement depending on the information of pixel density which the receiving unit receives.
