Handheld scanners are becoming more and more popular every day. A handheld scanner accomplishes the same task as that of a flatbed scanner with the advantage of portability. For those who do not have desktop space available to dedicate to a flatbed scanner or those who want to scan documents and pictures on the go, portable scanners can be of great use.

However, do not expect the accuracy of a flatbed scanner for a portable one. The quality of the scanned image will depend on user’s steady hand and movement.

Or you can choose Multi-Function Printers over scanners because they can do a lot of home as well as office works for sure including printing, scanning, copying and faxing. The right balance between print quality, scan quality and ease of use must be taken into account while choosing one.

How to choose the right scanner?

Duplex Scanners

Scanners with the duplex feature can scan both sides at once. It is faster, less time consuming and energy efficient. But it costs more.


Another very important factor to consider. There is the optimum resolution for each purpose. For example, to scan documents 300 dpi is enough while for scanning photos, minimum 600 dpi is a must. Likewise, if you need to scan the details thoroughly, (eg: 35mm slides and negatives, easily damaged documents like stamps), you will need at least 3000 dpi resolution.

Color Depth

Color depth refers to the number of different colors that the scanner is capable of recognizing and saving i.e the amount of information per pixel. Therefore, greater the pixel higher the quality larger will be the image size. The most common specification is 16-bit, 24-bit, 32-bit, and 48-bit. For general purposes up to 32-bit is more than enough. For extreme graphics scanning, you may need 48-bit.

Scanning area size

Most scanners are labeled as letter size. But if you need to scan larger documents, consider legal size scanners.


There are 2 types of wired connections. USB and SCSI. USB is reliable and faster. Scanners these days come with WIFI connectivity. You can easily scan documents and pics even from smartphones. Look for Wi-Fi options when buying one.
