A system is provided in which a memory is divided into two parts, so that a substantially continuous printing operation can be carried out by reading information to be printed from one part of the memory, with printing being interrupted for brief periods of time to permit writing of information in the other part of the memory. The writing into the memory is done on an alternate line basis, with the omitted lines being filled during a subsequent write operation so as to convert the interlace input to a standard format. At an appropriate time, the two parts of the memory are switched so that the read-out for the printing is carried out from the part into which information has just been written, and the writing takes place in the part of the memory which has been cleared during the preceding read operation. |
