Abstract There is provided an apparatus for aligning the printing data of a serial printer including: a controller (10) for controlling the system of the serial printer; a decoder (20) for decoding the data signal of the controller to sequentially enable the printing data, the decoder (20) being enabled by the enabling signal of the controller; a first buffer (30) for buffering the printing data of the controller, the first buffer (30) being enabled by the enabling signal of the decoder (20); a second buffer (40) for buffering the data of the first buffer to shift to a desired amount; a shift register (50) for shifting the data of the first buffer to the amount of the odd and even numbered data of the second buffer by the clock pulses applied from the controller, said shift register (50) being enabled by the output of the decoder (20); and a third buffer (60) for buffering the shifted data of the shift register (50) to apply the data to the printer head.
An apparatus for aligning printing data of a serial printer comprising: a controller for controlling the system of said serial printer; decoder means for decoding a data signal of said controller to sequentially enable the printing data, said decoder means being enabled by an enabling signal of said controller; first buffer means for buffering the printing data of said controller, said first buffer means being enabled by the enabling signal of said decoder means; second buffer means for receiving the printing data and enabling signal of said controller to buffer the data of said first buffer to shift to a desired amount; shift register means for shifting the data of said first buffer means to the amount of odd and even numbered data of said second buffer means by clock pulses applied from said controller, said shift register means being enabled by the output of said decoder means; and third buffer means for buffering the shifted data of said shift register means to apply the data to a printer head.
