A comparison of requirements and designs for barcode and non-impact printer scanners reveals similarities and differences that may be useful in leading to new solutions for barcode scanner problems. The non-impact printer scanner has been in volume production for over 10 years successfully achieving low cost high performance and high quality targets. Where requirements are found to overlap solutions already implemented and proven for printer applications may fmd further application in bar code scanners. Typical technologies used for printing include flying spot scanners liquid crystal shutters scophony scanners and LED arrays. Of primary concern in measuring figure of merit are such critical parameters as cost lifetime reliability conformance to regulatory standards environmental ruggedness power consumption compactness insensitivity to orientation acoustic noise produced modularity spot size depth of field exposure level and uniformity data rate scan length and uniformity and many more. A comparison of printing technologies their capabilities and their limitations with those used in barcode scanners may reveal common problems where we can take advantage of work already completed in similar application where requirements are found to overlap.
