Abstract

The invention discloses a printing method for rotating table transverse line in 24-needle printer. The principle is described as follows. 1) Printer memory is used to set needle rotating printing model and relative parameters in operation panel and menu. 2) After starting offset x of needle number of printing transverse line before shut down in last time is read from the memory and the next offset X is rotated; the range of X value can not go beyond the range of printing needle; aiming to the 24-needle printing head, the maximum range of X value is -11<=X<=11; when the X value is the maximum value, the value should jump to the minimum value; or when the X value is the minimum value, it should jump to the maximum value. 3) If the offset X is positive, read tab lattice data moves upwards in X integrally; if the offset X is negative, read tab lattice data moves downwards in X integrally. 4) a piece of printing paper is used as a basic unit; as the paper exchanging action is carried out the offset of tab transverse line rotates automatically and the offset of current printing transverse line is recorded in the memory.

Description

A kind of 24 impact printers are rotated form horizontal line Method of printing automatically

Technical field

The present invention relates to the print-out method of printer, particularly a kind of form horizontal line Method of printing of 24 impact printers.

Background technology

When current 24 impact printers are printed transverse meter line in character mode, all be to adopt fixing 1 pin or 2 stylus printer seals, print with the 12nd stylus printer as single horizontal line, two horizontal lines then adopt the 12nd, 13 stylus printers seal, therefore, often the pin that uses can wear and tear even rupture at first, in order to prolong the service life of the 12nd, 13 pins, guarantee print quality, so develop a kind of research schedule that form horizontal line Method of printing has been put on people of rotating automatically.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of 24 impact printers and rotate form horizontal line Method of printing automatically.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of 24 impact printers are rotated form horizontal line Method of printing automatically, and its step is as follows:

1) utilizes memory in the printer, use guidance panel and menu setting pinwheel to change printing model and relevant parameter;

2) the preceding offset X of printing horizontal line pin number of last shutdown is read in the start back from memory, and be rotated to next offset X, the X span can not exceed the scope of print needle, for 24 pin printheads, X maximum occurrences scope is-1≤X≤1, when X equals maximum, and palpus rebound minimum of a value, or when X equals minimum of a value, palpus rebound maximum;

3) be positive number as offset X, just the tab dot array data that reads moved X on the whole; As offset X is negative, just the tab dot array data that reads is moved down X as integral body;

4) be base unit with a type face, whenever once skip and move then form horizontal line side-play amount automatically by turns once, and the side-play amount of current printing horizontal line is recorded in the memory.

The invention has the beneficial effects as follows: this method is utilized 12 ± X, the form horizontal line that 13 ± X stylus printer seal is printed by the 12nd, 13 stylus printers originally, owing on average used original pin and 2 adjacent pins, effectively prolong the whole service life of printhead, in addition, this method is carried out upper and lower skew with the relevant dot array data of tab, thereby cause character to have on the upper side with respect to the form horizontal line or phenomenon on the lower side, because deviation seldom,, thereby effectively guaranteed print speed so this method is not carried out the paper feed compensation.

The specific embodiment

A kind of 24 impact printers are rotated form list horizontal line Method of printing automatically, and its step is as follows:

1) utilizes memory in the printer, use guidance panel and menu setting pinwheel to change printing model and relevant parameter;

2) offset X of horizontal line pin number is printed read last shutdown from memory before in the start back, and is rotated to next offset X, as side-play amount 0, then is rotated to next side-play amount 1, and the side-play amount span is (-1,0,1);

3) because offset X is a positive number, just the tab dot array data that reads is moved 1 on the whole;

4) be base unit with a type face, based on this side-play amount, one of every acceptance is skipped sign indicating number then automatically by turns once;

5) when withdrawing from pinwheel and change printing model, then the offset X with current printing list horizontal line is recorded in the memory.

This method is utilized the 11st, 12,13 pins to take turns and is printed the form list horizontal line that is printed by the 12nd stylus printer originally, owing on average used three pins of printhead, makes that the whole service life of printhead is original three times.

A kind of 24 impact printers are rotated the two horizontal line Method of printings of form automatically, and its step is as follows:

1) utilizes memory in the printer, use guidance panel and menu setting pinwheel to change printing model and relevant parameter;

2) offset X of horizontal line pin number is printed read last shutdown from memory before in the start back, and is rotated to next offset X, as side-play amount 1, then is rotated to next side-play amount-1, and the side-play amount span is (-1,1);

3) because offset X is a positive number, just the tab dot array data that reads is moved 1 on the whole;

4) be base unit with a type face, based on this side-play amount, one of every acceptance is skipped sign indicating number then automatically by turns once;

5) when withdrawing from pinwheel and change printing model, then the offset X with the two horizontal lines of current printing is recorded in the memory.

This method is utilized the 11st, 12,13,14 pins to take turns and is printed script by the two horizontal lines of the form of the 12nd, No. 13 stylus printer seal, owing on average used four pins of printhead, make that the whole service life of printhead is original twice.

Adopt above method Print Form horizontal line, mainly be that the relevant dot array data of tab is carried out upper and lower skew, thereby cause character to have on the upper side with respect to the form horizontal line or phenomenon on the lower side, because deviation seldom, so this method is not carried out the paper feed compensation, has effectively guaranteed print speed.The design has effectively prolonged whole service life, the good printing effect and the print speed of assurance of printhead; this method is not limited to 24 impact printers of above-mentioned enforcement; can also extend and apply on the various impact printers; as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
