Abstract
A method and system for rendering accurate bar code images in a distributed network wherein a plurality of different types of rendering devices, such as printers, having different resolution characteristics are connected for rendering such images. The resolution of a connected rendering device is detected and the bar code image to be rendered by such device is scaled to effect proper alignment of the resolution units of the bar code and the rendering device whereby the need for interpolation is effectively obviated. The bar code is scaled by a whole integer multiplier of the minimum bar code size based upon at least one dimension of the print area of the bar code display and the resolution characteristic of the rendering device. The bar code image is aligned or mapped and is centered in the display area with equal units of the excess print area on either side of the image. By avoiding the need to interpolate print data by the rendering device, the bar code rendering system defeats inaccuracies in detection and decoding and provides a more reliable data recovery system.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
