Abstract

PURPOSE:To certainly prevent the generation of line feed shift even at the time of printing wherein a character and a graph are present in a mixed state, by setting the min paper feed unit possessed by a printing apparatus as a line feed unit to open the same to the software of the printing apparatus. CONSTITUTION:In a 24-dot kanji printer, a dot pitch is set to 1/180'', a min paper feed unit to 1/120'' and the line feed between characters to 1/4'' line feed. Printing is performed according to the following order. At first, an order for printing a character part 21 is issued from software and a line feed number is not set. Next, an order for printing a graph part 22 is issued to perform graphic line feed as shown by a numeral 30. Subsequently, the remaining graph part 23 of a graph is printed. The printing up to this time can be performed in the line feed unit opened to conventional software but, when the printing of the next character part 24 is performed, a 1/120'' unit is set as a line feed unit to be opened to the software of the printer and, for example, a line feed number 14 is indicated from the software to make it possible to perform the line feed of the remaining line feed 14/120''. Therefore, line feed shift as conven tional is not generated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a printing device such as a Kanji serial printer connected to an office computer.

[Technical background of the invention and its problems]

In conventional Kanji serial printers connected to office computers, the line feed units open to the software are 1/6" and 1/8".

These are 1/4", 1/24" units, and graphic units. Recent kanji serial printers of this type perform graph processing in addition to normal character printing, and print a mixture of characters and graphs.

However, the line feed unit that can be used with the software of conventional Kanji serial printers is limited to a certain number of line units as mentioned above.For example, when printing a mixture of characters and graphs, the line feed may be shifted. There was a problem that there was.

[Purpose of the invention]

The present invention solves all of the above-mentioned conventional problems, and provides a printing device that can be connected to a CPU such as an office computer and can reliably prevent the occurrence of misaligned line feeds even when printing a mixture of characters and graphs. The purpose is to provide.

[Summary of the invention]

The printing device according to the present invention includes a means for specifying the minimum paper feed unit of the printing device in the printing device connected to the CPU, and a means for specifying the minimum paper feed unit of the printing device, and for analyzing the command specified by this means and calculating the number of lines specified by the software. The invention is characterized by comprising means for converting the number of line feeds into the minimum paper feed unit υ, and means for transmitting the line feed data converted by the means to the printing device, and converting the number of line feeds into the minimum paper feed υ unit of the printing device. Convert to units,
By doing this, we can obtain line breaks for the order line data, and even when printing a mixture of text and graphs, will the line breaks be misaligned? It can be prevented.

[Embodiments of the invention]

FIG. 1 is a block diagram showing a schematic configuration of an embodiment of the present invention, where I is a CPU, 2 is a main storage device, 3 is an I10 controller device for performing line feed processing in the present invention,
4 is a Kanji serial grinta. In FIG. 1, the configuration and operation of each part of the present invention other than the r10 controller device 3 is the same as that of a conventional printing device, so a complete explanation thereof will be omitted. This I10 controller device 3 is configured to convert the number of lines specified by software into the minimum paper feeding unit of the Kanji serial printer 4 and transfer the line feed r-ta'kA character serial printer 4.

The entire operation of the I10 controller device 3 will be explained in detail with reference to FIG. What is shown in Fig. 2 is an example of a case where characters and graphs are mixed and printed, where 20 is printing paper, 21,
24.25 are the character parts printed on each line, 22
and 23 are each graph portion.

The printer according to the embodiment shown in FIG. 2 is a 24-dot Kanji printer, with a dot pitch of 1/180", a minimum paper feed unit of 1/120", and a line break between characters of 1/4". In Figure 2, the printing order is as follows: First, the software issues a command to print the character part 21, with no number of line breaks.Next, it issues a command to print the graph part 22, and prints 30VC, a graphic line break (in this example, 24 dots 7180", which means a line feed of 16/120" when converted to the printer's minimum paper feed unit).Next, the remaining graph part 23t is printed.Printing up to this point is done using conventional software. It is possible to print in line feed units that are open to , but the next character part 2
When printing all 4, the printer head is already 1
Since there is a line break of 6/120", in order to make the 1/4" line break shown in 31 between character part 21 and character part 24, the remaining line break shown in 32 must be 14/120" (-174
"-16/120"), but in the conventional line feed specification above, for example, a 1/24" line break would be 15/120", whereas this 14/120" line break specification would be However, according to the present invention, the minimum paper feed unit of the printer, that is, in this embodiment, 1/120'' unit is set as a full line feed unit, and the line feed is shifted. By specifying the number 14i, the remaining line break 14/
Since the line feed can be performed above the line feed of ``l20'', the line feed shift that occurs in the conventional method does not occur.

〔Effect of the invention〕

According to the present invention, in a printing device that is not connected to a CPU, by opening the minimum paper feed unit owned by the printing device as a line feed unit to the software of the printing device, when printing a mixture of characters and graphs. However, excellent effects such as being able to reliably prevent the occurrence of misaligned line breaks can be achieved.
