Your printer cable can be connected to the printer pass-through port located in the rear of the scanner. When you are satisfied with a scanning image, you can print it out by the printer. Please turn off the scanner, and check whether you have unlocked the lock located at the bottom of the scanner. It's definitely possible to scan a 3D object by using our scanner as long as the object to be scanned is thinner than the lid can open up. If the object is too high, it will affect the scanning light, the depth of field, and of course, the image quality.
Optical resolution is the original resolution provided by the scanner optical device.
Interpolated resolution is the resolution enhanced through software. Though Interpolated resolution improves OCR recognition ability, the image produced through this type of resolution is inferior in quality and crispness to the image produced by optical resolution. Normally, OCR software performs with satisfactory recognition capability under 150 dpi resolution. That's why your scanning result is under 24 bit file format.
