Abstract: Technologies for electronic bill pay with check processing include a check print server coupled to a printer and a scanner. The check print server receives multiple bill pay requests, generates multiple pre-print checks based on those requests, and provides the pre-print checks to the printer. The printer prints the checks, and the scanner scans the printed checks and generates check images. The check print server updates a check record for each printed check with a hash of a combined front side image and back side image of the printed check. The check print server receives a check image request that includes a requested hash value and then returns the front side image and the back side image that match the requested hash value. The check print server may receive a check re-print request including a requested hash value. Other embodiments are described and claimed.
