> As far as `Dynamic Web TWAIN` is concerned, a network scanner is just like a local scanner because its driver has taken care of the network connection behind the scene.
### Scan From an eSCL Scanner
Many modern scanners and multi-functional printers (MFPs) support the eSCL protocol. The protocol is a vendor-neutral network protocol that allows driverless scanning via ethernet, wireless and USB-connected devices. eSCL-compatible scanners advertise themselves via mDNS so that we can find them easily. mDNS is a zero-configuration service. It is implemented by Apple Bonjour and the open-source Avahi software packages.
> See [this blog post](https://www.dynamsoft.com/blog/announcement/dynamic-web-twain-escl-scanner/) for more information about eSCL.
- To scan from an eSCL Scanner to PC, the Dynamsoft Service must be installed on the client PC
- To scan from an eSCL Scanner to Android, you must install the Android Service on the client device from the [Play Store](https://play.google.com/store/apps/details?id=com.dynamsoft.mobilescan).

The following code shows how one way to acquire the image via the eSCL protocol.
``` javascript
//Get the list of available eSCL scanners
let esclDeviceList=await DWObject.GetDevicesAsync(Dynamsoft.DWT.EnumDWT_DeviceType.ESCLSCANNER)

//Select the desired scanner from the list
await DWObject.SelectDeviceAsync(esclDeviceList[0])

//Acquire image (with configuration)
await DWObject.AcquireImageAsync({Resolution:100,IfShowUI:false})
```
