• How to create a program with a scanner on the network. TWAIN@Web - Scan documents over a network

    Instructions

    Download RemoteScan 5 to share the scanner over the network in Windows. You can download it here http://www.remote-scan.com/. Install the server version of the program on the computer to which the scanner is connected. Install the client version of the program on other computers on the network. When installing latest version the program will display a message saying that the scanner is , don't worry, this is normal. After installing the server version, a program icon will appear in the tray. Right-click on it and go to “Settings” to connect the scanner to the network. Select the scanner and configure the ports. The scanner may not be able to detect it right away; it will take from one to three minutes.

    Open your firewall/antivirus and allow access to port 6077, if you have NOD 32 antivirus, go to your personal firewall, go to interactive mode in the settings and create a separate rule for the RemoteScan program. After this, install the client versions on other computers. Network installation on Windows is complete.

    Set up network scanner on Ubuntu OS. Go to the terminal, enter the command #apt-get install and enter the name of the desired package - sane-utils, then open the scanner configuration file, which can be located in the /etc/sane.d/ folder with the name saned.conf, add the address to the end of the file the computer to which you want to share the scanner. Edit the file #nano /etc/inetd.conf, add the line sane-port stream tcp nowait saned:saned and specify the following path /usr/sbin/saned saned.

    Create a Scanner group: #groupadd scanner. Add users to this group group with the following command: # #usermod -aG scanner “Username”; usermod -aG scanner saned. Edit the file 40-libsane.rules, located in the nano /lib/udev/rules.d/ folder, and find your scanner there. Make the line with the name of the scanner look something like this: # “Name of the scanner”; ATTRS(idVendor)=="03f0", ATTRS(idProduct)=="4305", ENV(libsane_matched)="yes", MODE="664", "Group name"="scanner".

    Set up the client computer: install the sane-utils package using standard program install apt-get install packages, edit the net.conf file located in the nano /etc/sane.d/ folder, add the address of the computer with the scanner to the end of this file. The scanner's network connection is complete.

    In contrast to Windows, which is easy to install and configure, Linux has become a symbol of complexity and complexity of installation that can scare off anyone who does not consider themselves a virtuoso. command line and a highly qualified programmer capable of independently writing missing driver unknown device.

    However, installing and setting up ubuntu is the most popular among beginners Linux distribution- no more complicated than any other operating system. This distribution is ready to run immediately after installation and includes everything necessary for work: a client for communicating via the ICQ protocol, a client email, photo tool, audio and video player, office suite OpenOffice. In addition, a change tracking mechanism is implemented here. software, eliminating the need to monitor the release of new versions.

    3. In the menu that appears, select “Install ubuntu”

    4. You will need to select the language for communication again during the installation process and specify the time zone.

    1. Connect and configure the router. This process is quite simple and accessible to any user. Follow the instructions provided in the documentation for your model. We only note that if this is possible, then it is better to distribute IP addresses automatically. This will simplify the procedure for logging into the network for new equipment.

    2. Configure each computer to work in wireless network. Most have a built-in wi-fi adapter, but for a desktop computer you may need a network adapter, which will need to be purchased separately. Setting up a wireless network is not much different from setting up a regular network. The only thing you need to do additionally is to enter a special secret code network generated by the router. The code will allow you not to worry about outside users will be able to connect to your wireless network.

    3. To connect to a wireless network pocket computer The easiest way is to use the built-in iPAQ Wireless utility or similar, depending on the model of your pocket computer or. Here you will also need to indicate secret key networks.

    After you have managed to set up Wi-Fi, you can not only access the Internet from each device on the wireless network, but also use the network: share folders, share a printer and scanner, etc.

    Surely you are familiar firsthand with the situation when there are two or more personal computers. The exchange of information between them, the use of one printer or scanner, as well as other peripheral devices, requires the existence of a network. But PC users require not only access to local resources, but also to the open spaces global network. In view of this, you should figure out how to configure exit V Internet from general modem.

    Please note

    Assigning to each of the computers local network IP address, check them carefully to avoid duplication, since the IP address is the same electronic devices may cause their conflict and, as a result, the impossibility of working on the same network.

    Useful advice

    On the “Main Gateway”, that is, the modem, enter the first address (for example, 212.120.0.1), and select the IP address for personal computers included in the local network from the range 212.120.0.2 - 212.120.0.255. The subnet mask for all devices will be the same.

    The Internet is replete with articles on the topic of settings public access to printers, but find good instructions on the topic “How to set up shared access to a scanner on a local network” is quite difficult, because novice users encounter problems during independent decision problems.

    Main feature in setting up shared access to the scanner lies in its drivers, which control the operation of the device. User and operating system interact with the scanner through drivers, therefore they must contain a mechanism to support shared access to the scanner for remote use.

    To make sure that interaction occurs at the driver level, try running a scan from third party application, whether the operating system's Fax and Scan tool or graphic editor. Be sure to get into proprietary utility from the scanner developers. Therefore, if at the stage of writing software for the scanner this point was not taken into account, which is important for old devices that are not supported by the manufacturer, then public access to such a scanner cannot be organized.

    IN technical documentation the MFP must have everything necessary information regarding the use peripheral device, including over a local network. If there is no such data or it is difficult for the user to understand, help will come this instruction. It shows, using an example, how to connect and configure a scanner in the Windows operating system in order to scan documents over a network.

    In our case, we used a PC with Windows 7 and an HP scanner. XnView and Blind Scanner were used as accompanying software to open public access to the scanner.

    What is a network scanner?

    Note that there are two methods to “share” the scanner on the network. The first is to connect the device to one of the computers on the network and configure it accordingly. The second is to connect the scanner to the network as an independent device and make the appropriate settings. The connection methods differ in that in the first case the device will not have its own identification number(IP addresses) by which other network users will access it. Requests will occur through the mediation of the computer to which the scanner is connected. We will focus on this switching method due to its prevalence and ease of implementation. The second case requires a special device that is equipped with an integrated network card for individual operation in computer network, or a hybrid scanner. It can work either separately from a PC on a local network or connect to a computer via USB or Bluetooth.


    The ability to use the scanner over a network requires that the computer controlling it be turned on and connected to the network.

    Let's start setting up public access on the server

    First of all, you should connect multifunctional device or a scanner to a computer via USB and supply power to it, provided that the drivers are installed in the system. Otherwise, download them from the developer or device support website and install them. Then you should restart your computer and scanner.


    Now you should install a utility with the option of scanning documents, if the system does not have one. You can use, for example, XnView.


    Installing the application is very simple, so any beginner can follow all the instructions.

    Client machine configuration

    Then we switch to the computer from which we will perform network scanning and install the BlindScanner program on it, taking one point into account: in the component selection window, move the checkbox to the “BlindScanner Pro TWAIN driver (Client)” position.

    Using the scanner over a network



    As a result, we will receive a digitized document.

    It often happens that in addition to a remote printer, you also need a remote scanner to work. And if setting up a printer on a local network is not a lot of work, then with a scanner everything is much more complicated. The fact is that Windows OS does not provide tools for sharing the scanner. This is done at the level of its drivers. Therefore, to open access via a local network, you need to use third-party programs.

    The Blind Scanner utility is great for this, it works exclusively with scanners, making them visible to all computers on the network. The program is installed on each computer in client mode, and on the computer to which the scanner is connected - in server mode.

    After installation, the program will automatically start the server service and will work minimized to the tray. By opening the program window, you can see the operating mode of the service, its status (active or not), as well as the scanners connected to the computer.

    The utility is active and accessible over the network. Now it needs to be installed on all computers from which the scanner will be accessed, in client mode.

    After the installation is complete, the “Scannito lite” program will launch, in which you need to select BlindScanner Pro.

    A scanning window will open in which you need to search for the program server. To do this, you need to open the settings (as in the screenshot) and enter local address computer to which the scanner is connected.

    After this, a connection attempt will be made. If everything is entered correctly, then after a couple of seconds you will be able to see the scanner itself in the field.

    Select the scanner model in the drop-down menu, after which you need to set the settings: resolution, color mode, paper size and contrast and brightness settings.

    Now you can start scanning. Upon completion, the result will be displayed in the preview window, after which you can save it to any directory. Just like a printer, only one computer can access the scanner; the second must wait for the first to finish working.

    This is the easiest and at the same time reliable way to share access to the scanner. It can be used both in the office and in home network when it is not possible to move the scanner from place to place. Also, any program that supports scanning, for example, ABBYY FineReader, can act as a client.

    A system administrator, by the nature of his activity, needs to know: how many computers are on the local network he serves, their names and IP addresses, how many general network resources (folders, printers, etc.) created. In addition, he needs quick access to any of these shared folders. But if there are a lot of computers on the network with shared resources, then this task is quite problematic.
    Programs help solve this problem - resource scanners, which perform a monotonic study of the network and calculate nodes that have shared resources. One of the most famous such programs is (old name).

    The program can be downloaded from the official website. It is paid, but there is a free trial period.

    We install it as usual. During installation, you may also be prompted to install another utility: . Decide for yourself whether to install it or not. Personally, I don’t need it, because... computers with wi-fi adapters not on my network. So I unchecked this box:

    After launching the program will inform you how many days it will work in free mode– press the button “ Continue” (“Continue”):

    The interface language can be changed to Russian. To do this, go to the “File” – “Language” item in the menu bar and select Russian.lng.

    Let's get started with the program. First of all create a new goal, for which you need to select in top list menu TargetAdd:

    Enter any target name: I named “ My network ”:

    In the window that opens, write a name that is clear to you: for example, “ Office network " Next, indicate the range of addresses that need to be scanned (you can use the “Find IP range” button). Click OK:

    After the address range is specified, to start scanning the network, you must select the menu in the top list ScanningScan:

    The scanning time depends on the size of the range, the number and type of resources found, etc. In the status bar below you can see the scanning progress indicator, as well as the number of addresses and computers that have already been scanned.

    After your network has been scanned, the names of all computers and their IP addresses will be displayed on the screen. If any of the computers has a shared resource, a check mark will appear to the left of it. By clicking on it, we will see a drop-down list that lists all shared resources of this computer: shared folders, printers, etc.

    IN in this example on a car with a name COMP there is a common Canon printer and general Users folder . We can open it directly from this window double click this folder.

    This is how it turns out: computers with shared folders are on different floors of the building, but we see them all at once in one window and can go into any one.

    Has quite a lot of settings with which you can influence appearance interface, scanning parameters (for example, add checking for FTP and HTTP servers), information display.

    The program (old name) can be called an indispensable tool for searching necessary information in local networks in minimal time.

    Types of scanners and their compatibility with Windows

    Consider setting up a regular scanner and using the WSD service. To do this, connect the equipment to networks, make sure that scanner included. Click "Start" and go to the "Network" tab. Find the icon scanner and by right-clicking on it, select “Install”. In the User Account Control dialog box, click Continue. Click on the line “Your device is ready to use”, check the settings and click “Close”.

    Now click on “Start” again, find the “Control Panel” option, go to “Devices and Printers”. Make sure you have a network connection scanner A. Now perform a scan using the WSD service. Network name scanner and will be displayed on all computers participating in the local connection networks.

    Please note

    The WSD service is available in the systems Windows Vista.

    Useful advice

    The network scanner icon will be displayed with the name of the hardware being used.
