To view the print size on-screen:
Do one of the following:
Choose View > Print Size.
Select the hand tool or zoom tool, and click Print 
Size in the options bar.
The magnification of the image is adjusted to 
display its approximate printed size, as specified in 
the Document Size section of the Image Size dialog 
box. Keep in mind that the size and resolution of 
your monitor affect the on-screen print size.
Scanning images
Before you scan an image, make sure that the 
software necessary for your scanner has been 
installed. To ensure a high-quality scan, you 
should predetermine the scanning resolution 
and dynamic range your image requires. These 
preparatory steps can also prevent unwanted color 
casts from being introduced by your scanner.
Scanner drivers are provided and supported by 
the manufacturers of the scanners, not Adobe 
Systems Incorporated. If you have problems with 
scanning, make sure that you are using the latest 
version of the appropriate scanner driver.
Importing scanned images
You can import scanned images directly from any 
scanner that has an Adobe Photoshop-compatible 
plug-in module or that supports the TWAIN 
interface. To import the scan using a plug-in 
module, choose the scanner name from the File > 
Import submenu. See your scanner documen-
tation for instructions on installing the scanner 
plug-in. For general plug-in information, 
see “Using plug-in modules” on page 40.
If your scanner does not have an Adobe 
Photoshop-compatible scanner driver, import the 
scan using the TWAIN interface. (See “Importing 
an image using the TWAIN interface” on page 51.)
If you can’t import the scan using the TWAIN 
interface, use the scanner manufacturer’s software 
to scan your images, and save the images as TIFF, 
PICT, or BMP files. Then open the files in 
Photoshop Elements.
Importing an image using the TWAIN 
interface 
TWAIN is a cross-platform interface for acquiring 
images captured by certain scanners, digital 
cameras, and frame grabbers. The manufacturer 
of the TWAIN device must provide a Source 
Manager and TWAIN Data source for your device 
to work with Photoshop Elements.
