Disclosed is a method for determining optimum noise filter setting to be used by a scanner in a system including a printer and a detector forming a closed loop system. A test image including a plurality of horizontal lines, vertical lines, slanted lines and dots are printed using the printer and scanned back using the scanner. The scanned test image data is compared to the input test image data representing the test image, and based on such comparison, the optimum noise filter setting for the printer/scanner pair is determined and stored for future use. This method is particularly useful for printing barcodes having high data capacity.
