Abstract: A hand held terminal has a display, a keying input, a printer, a processor for receiving information from the keying input and for directing information onto the display and to the printer and a housing for the keying input, display and processor. The printer is directly mechanically connected to the housing and the printer is a sheet fed printer.

Abstract: A system and method for reading a two-dimensional image, and for comparing the two-dimensional image to stored data representative of a known image. The optical scanning device comprises a sensor for capturing the two-dimensional image, which sensor includes an LED array for projecting an emitted light towards the two-dimensional image. The sensor also includes a lens disposed forward of the LED array for focussing the emitted light and thereby framing the two-dimensional image. The sensor further includes an optical assembly for focussing an ambient light reflected from the framed two-dimensional image. And the sensor includes a CMOS (or CCD) detector for detecting the focussed ambient light, the CMOS detector including a photodiode array for sensing the focussed ambient light and a processor for processing the ambient light to obtain an electrical image signal. The optical scanning device also compresses the electrical image signal.
