[00341
An embodiment of the invention is described in detail below
using the device control system 100 as an example.
F I G . 8 illustrates the functional configuration of the device
control system 100.
The web browser 31 of the terminal 3 displays a web application
32 provided by the application server 2. The web application 32 calls
a device application programming interface (API) 33 of the web
browser 31. The device API 33 is, for example, a Java (R) script,
and as described below instantiates an object that controls a device
connected to the printer 5. The web application 32 calls (APICall)
an object of the device API 33. The device API 33 sends a request
(Request) to the printer 5 by a function of the called object.
[0035]
The device service interface 501 of the printer 5 receives the
request, and controls a device control script 502. The device control
script 502 controls a key ini~ut device 18 and serial communiqation
device 19. The device control script 502 acquires data input by the
key input device 18, and outputs data to the device service interface
501'. The device control script 502 handles data communication with
the serial communication device 19, and outputs data received from
the serial communication device 19 to the device service interface
501. The key input device 18 in this example includes the keyboard
14, and the serial communication devices 19 include the barcode
scanner 9 and cash drawer 13.
The device service interface 501 exchanges data with the local
printer55. The local printer55 is the localprint unit ofthe printer
5. The device service interface 501 also exchanges data with the
network printer 7 and customer display 8. The device service
interface 501 outputs device events (Event) and device responses
(Response) to the device API 33. The device API 33 outputs a response
(Callback) to the web application 32.
[0037]
A terminal 3 controls a device connected to a printer 5 in the
device control system 100 by the operation described above.
The invention is thus used to control devices (peripherals)
connected to a printer 5 in a multi-platform environment. By using
this system, devices can be controlled using a personal computer,
smartphone, or tablet computer in which a web browser is installed.
LOO381
The device API 33.has the following features.
* Can encrypt the content of device communications.
* Devices that operate according to a driver standard to the
OS of the printer 5 can be used through the device control script
502 without installing a specific driver on the printer 5. Because
thedevicecontrol script502 is writteninJavascript ( R ) , thedevice
control script 502 can be developed in the same language as the web
application 32.
* When a device is accessed using the device API 33, the device
is automatically exclusively locked. Multiple terminals therefore
cannot access and control a device at the same time. When the terminal
3 controlling a device releases the device, the device can then be
controlled from another terminal 3.
[0039]
The device API 33 also has the following features.
* Commands that print lines can be used when the network printer
7 or the local printer 55 of the printer 5 supports a line command.
* Buzzer functions can be used when the printer 5 or network
printer 7 is connected to a buzzer.
*Key codes that canbe acquired fromthe keyboard14 are limited.
Key codes that can be acquired from the keyboard 14 are shown in FIG.

2. Register web content
Register the web content in the printer 5 from the web browser.
The printer 5 can function as a web server to register web
content. The registeredweb content canbeviewed fromthewebbrowser
31 of the terminal 3.
The registered web content is compressed to a single file in
ZIP format containing all content files. The name of the ZIP file
can be specified as desired. The ZIP file name and subfolder names
are written using ASCII characters.
Web content cannot be appended, and all files are registered
by overwriting the old files. When accessing web content registered
in the printer 5 from the terminal 3, for example, the URL that is
accessed differs according tu the folder structure of the ZIP file.
Specific examples are shown in FIG. 11 (1) and (2).
