Abstract

PURPOSE:To make it possible to print oblique characters at a high speed while not requiring exclusive character pattern data to print oblique characters, and not becoming oblique characters in steps such as oblique character printing by conversion process by a method wherein by delaying printing timing of dots to constitute characters by a set interval, they are printed as oblique characters. CONSTITUTION:The title printer has a plurality of first to (n)th dot drivers which drive printing wires corresponding with printing dots of longitudinal 1 row of a dot matrix serial printer, a plurality of registers for printing data 2-1-2-n in which printing data fed per each dot driver is written, a delayed start timer 3 which outputs the printing data in the register for printing data to be printed next by delaying it in order each time when 1 dot of the longitudinal 1 row is printed, and printing timers 4-1-4-n which establish the delay quantity by this timer 3, and by the establishment of the delay quantity of the timer, the data for normal characters makes the printer print oblique characters in a range of 0-45 deg..

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing method for a printer, and particularly to a printing method for a printer that prints italic characters.

[Conventional technology]

Conventionally, in the printing method of printers, the method of printing italic characters with a dot matrix serial printer is to have pattern data exclusively for italic characters, or to convert the print data to print italic characters. Problem] In the printing method of the conventional printer described above, when a pattern dedicated to italic characters is provided, an extra dedicated memory is required. Also, it cannot support arbitrary character patterns. In addition, when printing italic characters by converting print data, the characters are pseudo italic, but the conversion processing part becomes step-like. There is a problem that the throughput decreases due to the processing time.

[Means to solve the problem]

The printing method of the printer of the present invention includes a plurality of dot drivers that drive printing elements corresponding to one vertical row of printing dots in a dot type printer, and a plurality of print data in which the print data supplied to each dot driver is written. It has a register and a delay circuit that sequentially delays and outputs print data in the print data register to be printed next every time one dot in the vertical column is printed.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In this embodiment, the vertical one of the dot matrix serial printer is
A plurality of first to n-th dot drivers that drive print wires corresponding to print dots in a column, and a plurality of print data registers 2-1 to 2-n into which print data supplied for each dot driver is written. A delay activation timer 3 that sequentially delays and outputs the print data in the print data register to be printed next every time one dot in one vertical column is printed.
and print timer 4 which sets the delay amount by timer 3.
-1 to 4-n, and by setting the delay amount of the timer, normal character data is printed in italic characters as shown in FIG. 2 in the range of 0 to 45 degrees.

Next, the operation will be explained.

Before starting printing, a timer value for the printing cycle is set in the print timers 4-1 to 4-n in advance, and a delay time for each dot is set in the delay start timer 3.

First, the data of the first dot column is stored in the print data register 2.
-1. When the print head moves to the printing start position of the first dot row, the first dot driver starts the print timer 4-1 and the delayed start timer 3 and prints the first dot of the first dot row. After printing, the print data is passed to the print data register 2-2. In this way, printing and data delivery are performed sequentially. At the same time that data is passed from the print data register 2-1 to the print data register 2-2, a print data request is output. In response to the print data request, the CPU sets new data in the print data register 1-1.

Delayed start timer 3, print timer 4-2, print timer 4
It starts in the order of -3 and stops when finished.

If no new data is stored, the print timers 4-1 to 4-n are stopped in order.

〔Effect of the invention〕

As explained above, the present invention eliminates the need for special character pattern data for printing italic characters by delaying the printing timing of dots that make up characters by a set interval and printing them as italic characters. Also, there is an effect that italic characters can be printed at high speed without forming stepped italic characters as in the case of printing italic characters by conversion processing.

Delay start timer, 4-1 to 4-n to print timer.

Claims (1)

[Claims] 1. A plurality of dot drivers that drive printing elements corresponding to one vertical row of print dots of a dot printer, and a plurality of print data registers into which print data supplied for each dot driver is written. and a delay circuit that sequentially delays and outputs print data in the print data register to be printed next every time one dot in one vertical column is printed. . 2. The printer printing system according to claim 1, wherein italic characters in a range of 0 to 45 degrees are printed using normal character data by setting a delay amount of the delay circuit.
