CHAPTER 1 TWAIN DRIVER OVERVIEW
Introduction
The Zebra TWAIN Driver for Windows enables an imaging scanner to capture and transfer images to a
TWAIN-compliant application. This driver conforms to portions of the TWAIN specification version 2.1 and
provides an interface for querying and setting TWAIN capabilities.
The Zebra TWAIN driver provides two interfaces:
•
A programmatic (non Graphical User Interface [GUI]) interface that supports capabilities described in the
TWAIN version 2.1 specification in addition to custom TWAIN capabilities specific to Zebra imaging
scanners.
•
A GUI that is accessible through TWAIN-compliant applications (see Figure 1-1).
Figure 1-1

CHAPTER 2 INSTALLATION &
CONFIGURATION
Overview
This chapter describes installation instructions and settings to configure the Zebra Scanner TWAIN driver on a
host computer.
For custom installation instructions, refer to the Zebra Scanner SDK Developer's Guide
(p/n 72E-149784-xx).
NOTE TWAIN components are installed by default with the standard Scanner SDK installation. If a custom
Scanner SDK installation is performed, the TWAIN option must be selected to install the TWAIN driver
components.
After a successful installation of the Zebra scanner TWAIN components, the Zebra TWAIN data source
(TWAIN.ds) is located in one of the following folders:
•
32-bit version: %SystemRoot%\twain_32\Zebra
•
64-bit version: %SystemRoot%\twain_64\Zebra
The required Zebra core scanner drivers are located in the folder:
%Program Files%\Zebra Technologies\Barcode Scanners\Common.
Visit http://www.zebra.com/scannersdkforwindows
to download the Scanner SDK installation program.

Enabling Logging in the Zebra TWAIN Driver
The Zebra TWAIN driver provides two logging mechanisms to assist with troubleshooting.
•
Application event logging viewable through the Windows Event Viewer under Windows Logs ->
Application.
•
File logging.
To enable logging, follow these steps:
1. Using the Regedit utility, go to the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Zebra\Zebra Scanners\TWAIN.
INSTALLATION & CONFIGURATION 2 - 3
Figure 2-1
2. To enable Windows application event logging, change the value of EventViewer from "0" to "1".
3. To enable file logging, change the value of Enable from "0" to "1" and provide a valid file path as the value
of LogFile. Ensure that the application has write permission to the location provided.
4. Restart the application.

Image Count: Corresponds to the CAP_XFERCOUNT capability in the range of 1 to 25 for the number of
image transfers the application transfers throughout the current session.
Image Enhancement: Sets the imaging scanner's ability to automatically enhance an image through a
combination of edge sharpening and contrast enhancement. Off disables automatic enhancement; Low,
Medium, and High perform those levels of image enhancement.
Rotate Image: Sets the degree of rotation of the captured image - 0, 90, 180, 270.
Enable Illumination: Enables the illumination banks on the scan engine. Check the box to enable
Illumination Bank Control.
Illumination Bank Control: Determines the operation of the illumination banks. Full enables both banks;
Auto switches the illumination system from left to right; Left enables the left bank; Right enables the right
bank.
Enable Auto Exposure: Enables the imaging scanner to automatically determine the gain and exposure
settings to best capture an image. Checking this box also enables the Gain Exposure Priority setting. If
Enable Auto Exposure is unchecked, the Fixed Exposure and Fixed Gain settings will be enabled
allowing the user to manually set those values.
GRAPHICAL USER INTERFACE 4 - 5
•
Gain Exposure Priority: Sets the scanner's gain/exposure priority when the Auto Exposure setting is
enabled - Autodetect, Low Gain or Low Exposure. Low Gain priority sets the scanner to favor longer
exposure time over higher gain to capture an image. Low Exposure priority sets the scanner to favor
higher gain over exposure for image capture. Autodetect sets the priority based on the scanner's
configuration. For example, if the scanner is mounted in a magnetic switch read enabled stand, it uses
Low Gain priority. Refer to the imaging scanner's Product Reference Guide for more information on this
setting.
•
Fixed Exposure: The manual exposure setting in the range of 5 to 5000.
•
Fixed Gain: The manual gain setting in the range of 1 to 100.
•
Brightness: Sets the relative brightness of the captured image in the range of -1000 to 1000.
•
Image Crop: Enables Image Crop Control. The Left, Right, Top and Bottom Pixel values determine the
rectangular sub-region of the full size captured image that will be displayed or transferred.
•
Left Pixel: Sets the left pixel column used to crop a captured image. This value ranges from 0 to
(Xresolution - 2) depending on the selected resolution (image size).
•
Right Pixel: Sets the right pixel column used to crop a captured image. This value ranges from 0 to
(Xresolution - 1) depending on the selected resolution (image size).
•
Top Pixel: Sets the top pixel row used to crop a captured image. This value ranges from 0 to (Yresolution
- 2) depending on the selected resolution (image size).
•
Bottom Pixel: Sets the bottom pixel row used to crop a captured image. This value ranges from 0 to
(Yresolution - 1) depending on the selected resolution (image size).
