Epson Scan 2 vs PaperScan

Epson Scan 2 is scanning software for Epson scanners and multifunction printers, with a graphical interface for scanner settings and saving scans in different file types. It supports USB connections and network scanning for compatible scanners. On Linux, network scanning requires installation of a plug-in package. Scans can also be started from the command line using a settings file, without opening the main window. Available image adjustments include background removal, text enhancement, color adjustment, descreening, color restoration, backlight correction, and skew correction. The Linux manual documents JPEG, PDF, TIFF, and Multi-TIFF output options. For OCR workflows, Auto Area Segmentation separates text from graphics, while Threshold can help OCR programs recognize text. Epson lists versions for Windows, macOS, and Linux, but supported operating systems and settings depend on the scanner model. Epson's Linux manual says the software has no official support and is distributed without warranty. Epson Scan 2 is free, but requires an Epson scanner or multifunction printer.

PaperScan is a Windows scanning application that acquires documents through TWAIN and WIA and includes OCR for searchable output.
