TWAIN Scanning

TWAIN (Windows and Mac) is a scanning protocol that connects scanners and applications together by providing standard interface. TWAIN allows applications to acquire images from TWAIN compliant devices (scanners, digital cameras, etc.). Most scanners come with TWAIN drivers that are installed automatically when you install the scanner in your computer. Please refer to your scanner documentation if there are no TWAIN sources available. When scanning using TWAIN PDF Studio will first launch the scanning application provided by the hardware, then once the scanning is complete import the scanned image to complete the Scan to PDF process.

Note: The TWAIN protocol is only supported in 32-bit installations of PDF Studio on Windows and Mac If you are using the 64-bit PDF Studio installation this option will not be available.

  1. Go to File > Create PDF >From Scanner > Twain or click on the small down arrow to the right of the scanning button and select "Scan to PDF (Twain)".
  2. Choose a scanner from the list and click on the OK button to proceed.  If there is an error with the selected scanner, the dialog will appear again with the previously tried scanner highlighted so you can choose a new scanner.  
  3. When the OK button is pressed, your scanner's custom scanning application will open. This is a separate program that will allow you to preview the scan, choose a region to scan, adjust the scan resolution, and then accept the scan using the software that came with your scanner.
  4. Once the scan has been accepted and PDF Studio has received the data from the scanner software, PDF Studio will display a dialog box showing some information about the scan and will prompt you for a number of choices to determine how to insert the new image.
  5. Once you've selected the options click OK to then create a new PDF or append the image to an existing PDF depending on the option selected.
