Abstract

PURPOSE:To obtain the result of distinct printing while improving throughput by conducting speed-doubling printing thinning continuously printing dots on lap printing. CONSTITUTION:When a printing-mode assigning command is used for lap printing, a printing counter 5 transmits the speed-doubling printing pulses of the width of t3 to t4 over a speed-doubling printing circuit 8 through an AND circuit 6 as the number of printing and a speed-doubling mode through a setting-start command decoder 5. Speed-doubling printing by one-time thinning printing is controlled for the times t3 to t4 by the speed-doubling printing circuit 8. When the signal of printing completion is transmitted from a printing control circuit 9, a printing counter 2 performs count-down, and two-time printing in which the same data is printed at the same position is conducted for the times t5 to t6. Accordingly, lap printing is conducted by speed-doubling printing only by required number. When the printing of one line is completed, printing proceeds to the printing of the next line.

(Example) An example of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing the main parts of an embodiment of the present invention. In the same figure, overlap printing mode latch 1
latches the overlap print mode when an overlap print command is input from an external interface or operation switch (not shown). The print start command decoder 5 receives the line print start command and calculates the required number of overprints using the print counter 2.
Send to. The print counter 2 sets the number of times of repeated printing from the decoder 5. For example, in the case of double printing, "2
" is set. The counter 2 is incremented by "-1" by the print completion information from the print control circuit 9, and the counter 2 is
When becomes "0", overprinting of that line ends. The counter 2 is newly set by the print start command for the next line. The print data buffer 4 latches received data that is input following the overlap print command.

The double-speed printing circuit 8 is means for performing double-speed printing by thinning printing, which will be described later. When the overlap print mode latch 1 is in the overlap print mode and the print counter is not rOJ, the AND circuit 6
The print data is printed at double speed. In this case, the data in the print data buffer 4 is held by a signal from the print control circuit 9 until printing is performed a necessary number of times. Printing involves printing the same data multiple times in the same location. The normal print mode latch 3 latches the normal print mode when a normal print command is input from an external interface or an operation switch (not shown). In the case of normal printing, the mode latch 3 sends the contents of the print data buffer 4 as is to the print control circuit 9 via the AND circuit 7.

The double speed control circuit 8 is the current data register lO
It consists of a previous print memory 11, an arithmetic circuit 12, a print data register 13, a print drive section 14, a high speed print circuit 15, and a space motor 16. The data register 10 in this case is a means for storing data for each dot from the print data buffer 4. The previous print data memory 11 is a means for storing data for each dot printed immediately before. The arithmetic circuit 12 is a means for performing arithmetic processing so as not to continue printing from the data in the register 0 and the memory 11. The print data register 13 is a means for storing data for each dot that has been arithmetic processed as described above as data to be printed this time. The print drive unit 14 is a drive unit that prints the data stored in the print data register 13. The high-speed printing circuit 15 is means for determining the printing speed for realizing double-speed printing. The space motor 16 is a motor that moves the print head laterally and is driven at a speed determined by the circuit 15 described above.

Next, the operation of the embodiment of the present invention will be described with reference to FIG. 1 and FIG. 3, which is a time chart when the normal print mode and the overlap print mode are designated. When the print mode designation command is normal printing, the print counter 2 and double-speed printing circuit 8 do not operate, and data 1 in the print data buffer 4 is printed only once between times t and t2. When the print mode designation command is overprinting, the print counter 5 is set to the number of times of printing and double speed mode via the print start command decoder 5, and a double speed print pulse with a width of ~t4 is sent via the AND circuit 6 to the double speed mode. It is sent to the printed circuit 8. The double-speed printing circuit 8 controls double-speed printing by first thinning printing between times t and t4. When a print end signal is received from the print control circuit 9, the print counter 2 counts down, and a second printing of the same data at the same location is performed between time t and 1G.
