Abstract

PURPOSE:To obtain a printer capable of printing by calculating actual position and size of printing by a method in which the relative position and size of printing range and non-printing range are designated for the two directions, the directions of line and digit, of a printing paper and also the size of the paper is designated. CONSTITUTION:Printing menu is selected at the step S1, printing routine is entered, a printing range key is pushed at the step S2, and a routine with a designated printing range is entered. In this case, a printing range menu is called. At the step S3, the value, or (left-handed non-printing range length=X):(line-direction printing range length=Y): (right-handed non-printing range length=Z) ratio, of paper is designated. At the step S4, the value, or (upper non-printing range length =L):(digit-direction printing range length =M):(lower non-printing range length =N) ratio, in the digit direction is set up to be a given value by the moving position of cursor CU and input. In the step 5, the size of paper is determined, and in the step S6, the printing key of an input unit 2 is pushed and printing is made. From the value of ratios in the two directions of the paper and the size of paper, obtained in the steps S3-S5, actual printing size is calculated in the step S7, and when the possibility of printing is judged in the step S8, printing is made.

Description

TECHNICAL FIELD The present invention relates to a printing device, and more particularly to a printing device in which the printing range is determined in two directions, the line direction and the 9-column direction, with respect to the printing paper by proportional values of the printing range and the non-printing range. .

The prior art was extremely complex, requiring information on many requirements such as spacing, vertical spacing, line pitch, and character pitch. In addition, especially regarding the relationship between printing paper and printing range, there are many cases where the operator's print image differs from the print image. There was a drawback that the line pitch etc. had to be changed every time the line was made.

Purpose The present invention has been developed in view of the above points, and is capable of printing by specifying the non-printing range and the printing range in two directions, the line direction and column direction, of printing paper using a ratio value. The purpose of the present invention is to provide a printing device that can calculate the actual printing position and size and print by specifying the relative position and size of the printing range with respect to the paper and also specifying the paper size. .

Also included are paper registers GREG, HREG that specify the paper size.

Note that the vertical and horizontal lengths of the paper are specified in the paper registers GREG, ., HREG. Also included is a cursor register CUREG that specifies the location where each of the above register values is input. 8 is a character generator which converts the character code read from the document storage buffer 6 into the screen refresh memory 3 into character pattern data and outputs it to the CRT 5.

Next, the printing apparatus of the present invention will be explained using the flowchart shown in FIG. In step S1, a print menu is selected and a print routine is entered. In step S2, the print range key is pressed to enter a print range designation routine.

At this time, the printing range menu is called up as shown in FIG. Here, CU represents a cursor. In step S3, the ratio value of (left non-printing range length - X): (digit direction printing range length = Y): (right non-printing range length - Z) of the paper shown in FIG. 4 is specified in step S3. -g (that is, the values of A, B, and C are
G and CREG are stored respectively. Next, in step S4, similarly to S3, in the digit direction (upper non-printing range length = L)
:(Printing range length in digit direction - M):(Lower printing range length FN) ratio D:E;F value is set to 0 predetermined value according to the movement position of cursor CU (:Set and input. For example , now D=2
When the values of E=11 and F=2 are input, these values are stored in the digit direction registers DREG, EREG,
Each is stored in FREG.

Next, in step 551, the paper size is determined. '17x, that is, the length and width of the paper as shown in FIG. 4 are input in inches by pressing the parameters G and H setting keys of the input device 2. As a result, the paper value is stored in the paper registers GRE, G, and HREG in the register 7. For example, if G = 100imH = 150 mm, paper register GREG f = 100 paper register HREG
150 is stored in .

When the print key of the input device 2 is pressed in step S6, printing is executed. Steps 53 to S5f described above
In step S7, the actual printing range is calculated from the ratio values in the two directions of the paper and the paper size obtained in step S7. T
That is, the lengths of each part of the paper in FIG. 2 are as follows.

If it is determined in step S8 that printing is possible, printing is performed as shown in FIG. Furthermore, if it is specified in step S8 that printing is not possible, for example, when the printing range is extremely small compared to the number of characters in one line, printing is disabled1], and step S8

In the above embodiment, the printing range is determined for one rectangle, but by selecting many points that take the ratio value in the two-digit row direction, the ratio value can be set for each rectangular block. As a result, even a complex block B as shown in FIG. 5 can be designated as a printing range. Furthermore, by providing a document range register that specifies the print range of a predetermined document within a page, it becomes possible to print the specified document in the predetermined print range of the specified paper regardless of the size of the paper. Further, in this embodiment, a display device CRT is used, but it goes without saying that the printing range can be specified even without a display device.

Effects As explained above, according to the printing device according to the present invention, printing can be easily specified by giving the ratio of the printing range to the printing paper in two directions, row and column, and inputting the paper size. It is possible to print in a form close to the print that the operator envisioned, and even if the paper size is changed midway through, the printing range is determined by the ratio to the paper size, so there is no need to make many new specifications for printing. can be made printable.
