Abstract
Aspects provide for a printer with automatic paper sheet count discovery, via determining an initial weight of printer paper sheets within a printer paper feeder tray. A single sheet is removed from the paper feeder tray to a staging area of the printer, and a revised weight is determined for the sheets within the paper feeder tray while the single sheet of paper is removed to the staging area. The single sheet is fed back into the paper feeder tray via a printing path bypass of the printer. The weight of the single sheet determined as a function of the difference between the initial weight and the revised weight. A quantity of printer paper sheets currently loaded within the paper feeder tray and available to satisfy a print job is determined as equal to the initial weight divided by the weight of the single sheet.
