Problems solved by technology

[0003] However, even with a compatible printer, the printer driver needs to be reassembled, requiring redundant operations, which is a problem
In addition, when using the converter function of the printer to process the printing data of other printer drivers, the plug-and-play relationship between the printer and the printer driver cannot be established, which is another problem.

[0022] figure 1 It is a block diagram showing the configuration of the printer system in the first embodiment.

[0023] The printer system 100 has a PC (Personal Computer: personal computer) 10 and a printer 20 . The PC 10 is a host-side device that is a source of a print request. The printer 20 is a peripheral device (device). The PC 10 and the printer 20 are connected to each other via a USB (Universal Serial Bus: Universal Serial Bus) data line 30 .

[0024] figure 2 for example figure 1 The shown schematic configuration of the PC 10 and the printer 20 in the printer system 100 is shown.

[0025] Such as figure 2 As shown, in the PC 10 as the control device, the CPU 101 constituting the calculation processing center controls the PC 10 as a whole through the bus 10a. A ROM (ReadOnlyMemory: Read Only Memory) 102, a RAM (Random Access Memory: Random Access Memory) 103, various interfaces (I / F) 104a to 104c, a hard disk drive (HDD) 105, and the like are connected to th...

[0056] Figure 6 It is a configuration diagram of main parts for explaining the second embodiment of the printer device. In this embodiment, the printer 20 has a converter 61 inside.

[0057] The converter 61 stores, as a program, an emulation function capable of processing commands from a printer of company B different from a printer of company A that has been used so far. Since the emulation function absorbs the difference in hardware design, it executes software called an "emulator" that imitates the "posture" of the original hardware, and makes the software work.

[0058] However, for a system in which the printer 20 is replaced with a company B printer, the PC 10 and the company B printer are combined. In this way, the printer itself becomes Company B's printer. Although the printer's command system can handle company B's commands, as equipment, it is still a company B's printer. Therefore, regarding the printer driver, the driver of Company B will be required.

[0071] Figure 8 It is a flowchart for explaining the third embodiment. In this embodiment, a request not to perform a printer driver is realized for a user who controls a printer driver by using an application software. In other words, when the PC 10 and the printer 20 are connected via the USB cable 30 , control to invalidate the device ID of the printer driver becomes possible.

[0072] exist Figure 8 , the printer controller 203 of the printer 20 issues a request whether to use the default printer driver when the PC 10 is connected (ACT 31 ).

[0073] In the step of ACT31, in the case of using the device ID (Yes), enter the device ID of the connected printer (ACT32).

[0074] According to the input of the default device ID in ACT32, a plug-and-play process (ACT33) occurs, and ends after the process is completed. (The first unit)

[0075] In this step of ACT31, without using the device ID (no), such as Figure 9 The indicated request inputs an arbitrary device ID in ...

Abstract

The invention relates to a printer unit and a printer system. By employing the printer unit, a printer driver does not need to be reassembled after a printer is changed. The printer is provided with a function of setting and changing the equipment ID. By means of the function that the printer can freely change the equipment ID, a printer provided with the universal equipment ID can be used just after being inserted into the printer system and can be identified as the printer being replaced. Accordingly, as long as the printer driver is provided with a universal equipment ID, a plug and play relation can be established, and troubles caused by reassembling can be avoided.

Description

technical field [0001] Embodiments of the present invention relate to a printer device and a printer system having a plug-and-play function. Background technique [0002] Conventionally, a printer has its own device ID (Identification: identifier), and through plug and play, a printer driver matching the device ID can be automatically assembled. This means that not only printers, but also all devices with plug-and-play functions have inherent device IDs, which are information that cannot be changed except for the purpose of assembling specific software. The relationship between a printer and a printer driver must be a one-to-one relationship. Therefore, when the printer is replaced, the printer driver must also be reinstalled. [0003] However, even with compatible printers, it is necessary to reassemble the printer driver, requiring redundant operations, which is a problem. In addition, when using the converter function of the printer to process the printing data of othe...
