Abstract

PURPOSE:To enable easy checking, by a system wherein selection of character generators is effected by a front key, and a selection indicating part is provided on the upstream of a printing region. CONSTITUTION:A main CPU 10 and a slave CPU 11 are provided. A standard character generator 12 represented as ROM1 and an optional character generator 13 represented as ROM2 are connected to the CPU 10. Where a line-feeding switch 7 is depressed, the standard character generator 12 is selected, and an indication 'ROM' is made at the selection indicating part 25 of a recording paper 24. When a feeding switch 6 is depressed, whether or not the optional character generator 13 is present is checked, and when the character generator 13 is mounted, an indication 'ROM2' is made at the part 25.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is equipped with, in addition to a standard character generator that determines the font of characters and symbols, a character generator that can print in other fonts as an option. This invention relates to printing devices.

BACKGROUND OF THE INVENTION In general, conventional printing devices are capable of performing test printing in order to check the general operating condition of the printing device. The content of this test print is a combination of specific characters and symbols, and these characters and symbols are printed solidly on the front surface of the recording paper.

On the other hand, in addition to the standard character generator, the printing device can be equipped with an optional character generator that can print characters and symbols in different fonts.

In a machine equipped with an optional character generator in addition to the standard character generator, selection between the two is done by means of a manually operated changeover switch and by software set by an external computer. There are means.

Problems to be Solved by the Invention First, in the case of the former changeover switch, the grounding position of the changeover switch is located on the back of the device or inside the case cover, and the paper feeding method, data transfer speed, and country of destination are It is mixed with switches that set various uses such as compatibility with characters. Therefore, it is difficult to check the changeover switch, and in order to find the changeover switch among the many switches that set various specifications, it is necessary to refer to the instruction manual attached to the device.

Furthermore, if the character generator is selected by software, it is necessary to open the case cover and visually confirm whether or not the optional character generator is installed, which is extremely troublesome. Furthermore, another method requires connecting an external computer, selecting an optional character generator, and printing and viewing.

Means for Solving the Problems A character generator is selected using a front key, and a selection display section is provided in the front part of the test printing area of the recording paper to display the type of the selected character generator. Perform test printing with the generator.

The standard character generator and optional character generator are selected using the front keys, and since there is a selection display section in the front part of the print area during test printing, it is easy to see which character generator is being used for test printing. It becomes clear.

Embodiment First, FIG. 1 is a plan view of a printer 1, in which a front key 3 and an indicator lamp 4 are arranged on the left side of a case 2. As shown in FIG. The front key 3 is 0N1
It consists of an 0FF line switch 5, a form feed switch 6, and a line feed switch 7. Further, the display lamp 4 includes a power lamp 8 and an online lamp 9.

Next, FIG. 2 shows the connection state of the internal circuit.

That is, it consists of a main CPU10 and a slave CPUII, and a standard character generator 12 indicated as ROMI and an optional character generator 13 indicated as ROM2 are connected to the CPU10. Also, a ROM 14 for programs, a RAM 15 used for memory and other purposes, and a receiving circuit 16 for receiving print data from a host computer (not shown).
are connected. Further, an input circuit 17 is connected to the CPU 10, and a dip switch 18 is connected to the input circuit, and the 0N10FF line switch 5 is connected via a flip-flop 19. 6 and a line feed switch 7 are connected.

Further, the slave CPU 1 includes a driver 20.
is connected to this driver 20, and a print head 21,
A carrier motor 22 and a paper feed motor 23 are connected.

In this configuration, it receives and edits print data, generates test data, reads various switches, and processes them. It converts the print code into a dot pattern and sends it to the slave CPU II. A feed command for paper feeding is also sent to this slave CPU 1l, and this slave CPU 11 operates subordinately to and under the control of CPU 10.

The operation will now be explained based on FIG. First, when you turn on the power, the initial setting routine will load RAM15.
In addition to clearing and reading the dip switch 18, a check is made to see if the line feed switch 7 or the feed feed switch 6 has been pressed within several meters from the time the power is turned on.

If the line feed switch 7 is pressed now, the standard character generator 12 is selected and the recording paper 24
Then print the test pattern.

In this test pattern printing routine, first the rPR
"INTER0945REV: 510" is printed in the program area. Next, a message “ROMIJ” is displayed on the selection display section 25.

Thereafter, printing is continuously performed on the test 1 in the print area 26 from the test 1.

Also, when the feed feed switch 6 is pressed,
A check is made to see if the optional character generator 13 is present, and if it is not, a test print is made using the standard character generator 2 described above; if it is, the character generator
Test printing of the data 13 is performed. In this case as well, after the necessary printing is done in the program area, the selection display section 2
5 is displayed as rROM2J.

In this way, by suppressing the feed feed switch 6 or suppressing the line feed switch 7 when the power is turned on,
A test printing routine is selected and one of the character generators 12 and 13 is selected. At that time, the display on the selection display section 25 makes it clear whether the optional character generator 13 is present or not, and which character generator 12, 1.3 is selected when the optional character generator 13 is present.

Next, if the feed feed switch 6 and line feed switch 7 are not pressed when the power is turned on, a check is made to see if it is online.

When online, normal printing operations such as data reception, data printing, and paper feeding are performed.

If it is not online, it waits until the feed feed switch 6 and line feed switch 7 are suppressed, and feeds the paper in accordance with the suppressed state.

Effects of the Invention The present invention provides a selection display section for selecting a character generator using a front key as in a double series, and displaying the type of the selected character generator in the front part of the test printing area of the recording paper. Since test printing is performed using the selected character generator, it is possible to easily check whether the optional character generator is installed by performing test printing, especially at factories or distributors. It is easy to operate and has great effects in terms of manufacturing and sales.
