Windows CE includes Print Server functionality. This functionality enables clients to access files and other resources, such as printers, from a server over a network using TCP/IP.

The Print Server uses the Common Internet File System (CIFS). This is an extension of the Server Message Block (SMB) file sharing protocol. CIFS enables a network-enabled application to access and manipulate files and directories on a remote server in the same way that it the application accesses and manipulates files and directories on the local system.

Print Servers support user-level authentication. This means that any client attempting to access a share on a server must provide a user name and password. When authenticated, the user can then access all shares that are not protected by share-level security on a server.

Windows CE provides a Web-based network configuration utility to configure your server, and manage both share and user permissions. This sample configuration utility is located in the %_WINCEROOT%\Public\Servers\oak\Samples\remoteadmin\modules\smbprint directory. To access the Web-based configuration page for your server, type the following information in the address bar in your Internet browser:

Http://<IP address of your server device>/remoteadmin

You can also modify these settings using the registry. For more information, see Print Server Registry Settings.

Print Server uses the IOCTL_SERVICE_REFRESH I/O control (IOCTL) and device.exe to reload these settings if they are changed without rebooting the device.

To reload your server settings

  1. Call the CreateFile function to open a handle to the "SMB1" service.
  2. To send the IOCTL, call DeviceIoControl on the open service. DeviceIoControl then calls the service-related xxx_IOControl (Services.exe) function, and passes in IOCTL_SERVICE_REFRESH as the dwCode parameter.
