Abstract

PURPOSE:To improve the working efficiency of a print terminal device by allowing both the print terminal device and a host CPU to apply registration, addition and change to a print pattern. CONSTITUTION:A printer 6 uses a character pattern stored to a character pattern storage section 5 to print data of a print data storage section 2. On the other hand, a communication processing section 1 receives all or a part of requested printed pattern from a host CPPU 8, then stores the character pattern to the storage section 5 to release the state under revision. Whether the printer 6 is operated by the command from the host CPU 8 or by the operation of an operation section (not shown) of the print terminal device side is controlled selectively by an operation management section 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing terminal device that can store, add, and change character patterns.

[Conventional technology]

Conventionally, for this type of printing terminal device, character patterns are stored using the local function of the printing terminal device.
Additions and changes to it were also made locally.

[Problem that the invention seeks to solve]

With the above-mentioned conventional printing terminal devices, when registering, adding, and changing character patterns to be used, these operations must be performed for each of multiple printing terminal devices, and operation and maintenance of character patterns requires manpower and time. At the same time, this method has the disadvantage of increasing complexity in character pattern management.

[Means for solving problems]

The present invention allows character patterns to be registered, added, and changed upon request from both the printing terminal device and the host computer.

That is, the terminal printing device of the present invention includes a communication processing section that receives print data and character patterns from a host computer, a print data storage section that stores the received print data, and a character pattern storage section that stores the received character patterns. 1, a printing device, a printing processing section that retrieves printing data from a printing data storage section, outputs it to the printing device, and notifies a character pattern corresponding to the printing data;
A character pattern loading processing unit that reads the notified character pattern from a character pattern storage unit and outputs it to the printing device when the notified character pattern is different from a character pattern that has already been output to the printing device, and a character pattern processing unit that outputs the character pattern to the printing device. When receiving an update instruction for registration, addition, or change from the printing terminal device side, the host computer is notified of this via the communication processing section, the character pattern storage section is put into an updated state, and the instruction is sent to the communication processing section. The apparatus includes an operation management section that puts the character data storage section into an updated state when the character data storage section is received from the host computer via the host computer, and releases the updated state when the update is completed.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a printing terminal device according to the present invention.

Communication processing unit 1 receives print data and character patterns from host computer 8 . The print data storage section 2 stores the received print data.The zero character pattern storage section 5 stores the received character patterns. The printing device 6 prints the print data in the print data storage section 2 using the character patterns stored in the character pattern storage section 5. The print processing unit 3 extracts print data from the print data storage unit 2 in the order in which it should be output, and notifies the character pattern load processing unit 4 of the character pattern name specified directly or indirectly in the print data. If the notified character pattern name is different from the character pattern name already output to the printing device 6, the processing section 4 reads it from the character pattern storage section 5 and outputs it to the printing device 6. Thereafter, the print processing section 3 outputs the extracted print data to the printing device 6. When the output of one print data is completed, the print processing section 3 takes out the next print data from the print data storage section 2 and starts the next cycle. In the above processing cycle, the operation management section 7 receives a character pattern update instruction (including registration, addition, and change) from the host computer 8 via the communication processing section 1, or upon a request from the printing terminal device. When an update instruction is given, the corresponding character pattern in the character pattern storage section 5 is brought into an updating state.

At this time, the operation management section 7 may immediately request a character pattern for update from the host computer 8 via the communication processing section 1, or the one-character pattern load processing section 4 may request the character pattern for updating from the printing processing section 3. The request may be made after waiting for the update to be detected.

On the other hand, when the communication processing unit 1 receives all or part of the requested character pattern from the host computer 8, it stores the character pattern in the character pattern storage unit 5 and cancels the updating state.

In the figure, solid lines represent the flow of data, and dashed lines represent the flow of control.

〔Effect of the invention〕

As explained above, the present invention enables the registration, addition, and change of one-character patterns to be performed at the request of both the printing terminal device and the host computer, thereby reducing time constraints on the operation and maintenance of one-character patterns. This has the effect of making it possible to centrally manage character patterns on the host computer, thereby increasing the operating efficiency of the printing terminal device.
