Title: Printing apparatus
Inventor: SAKAGAMI AKIRA
IPC: B41J29/46
Filed: 1990-10-30
Abstract: PURPOSE:To eliminate a wasteful time and to make continuous operation possible by constituting a control part so that the bit image of a printing data drawing part is printed by a printer to be stored in a memory part and a switch part is controlled so as to be changed over when trouble is generated to print the stared bit image by the printer. CONSTITUTION:A whole control part 1 sends out the printing data from a host apparatus to a printing data drawing part 2 converting said data to a print output image. At each time when the converting operation of the printing data drawing part is completed, the printing data is outputted to a printer part 3 through a switch part 5. The whole control part 1 stores the conversion data for trouble such as feed inferiority in the printing data drawing part 2 in the memory part 4 by necessary quantity having to convert said data to printing data simultaneously with the output operation to the printer part 3. Since the whole control part 1 changes over the switch part 5 from the usual printing data drawing part 2 to the memory part 4 even when trouble such as feed inferiority is generated during printing, the print output image conversion data at the time of the generation of trouble can be outputted to the printer part 4 from the memory part 4.
