Plustek SmartOffice PS3140U vs Epson WorkForce ES-580W
Compare two 100-sheet TWAIN scanners by connection, computer-free scanning and documented media limits rather than headline speed.
The decision in brief
How the options differ
Both list a 100-sheet feeder and a TWAIN driver. Choose the ES-580W if scans must leave the scanner without a computer: Epson documents Wi-Fi, a touchscreen and scanning to a USB memory drive. The PS3140U is USB 2.0 only and works through a connected computer, but Plustek publishes 600 dpi optical resolution, long pages to 200 in and plastic cards up to 1.2 mm, which the reviewed Epson page does not detail.

The buying guide
Package and specification details
Decide whether scanning must work without a computer
Epson documents Wi-Fi, a touchscreen and scanning to a compatible USB memory drive without a computer for the ES-580W. Plustek lists a single USB 2.0 Type B interface for the PS3140U; DocAction Plus on the connected computer can then send files to folders, network drives, email or FTP. That host software is not a built-in network interface. If the scanner will sit where no computer is attached, only the ES-580W documents a route.
Both document a TWAIN driver; check the exact application
Plustek lists the PS3140U as TWAIN compliant with its DocTWAIN driver, and its datasheet feature list also names WIA. Epson documents a TWAIN driver alongside Epson ScanSmart for the ES-580W. Either can therefore feed a TWAIN-capable document-management application, but TWAIN support is not a promise that every package and operating system works. Confirm the current driver for your host.
Same nominal feeder; Plustek documents more media detail
Both list 100 sheets. Plustek qualifies its figure at 70 g/m2 (18 lb) in the specifications, while its manual gives 80 g/m2 with a stack under 5 mm, and adds 30 business cards, plastic cards up to 1.2 mm and long pages to 200 in in Long Document Mode. The reviewed Epson US page does not publish comparable special-media limits or an optical resolution, so those are unknown rather than missing features.
Plustek claims 40 ppm / 80 ipm at 200 and 300 dpi in grayscale or black and white and at 200 dpi in color, and 30 ppm / 60 ipm at 300 dpi color, on A4 portrait pages. Epson claims up to 35 ppm / 70 ipm for Letter pages at 300 dpi in black, gray or color. Page size and test conditions differ, and neither figure is a measurement after OCR or file transfer.
Plustek publishes two OS lists for the PS3140U: Windows XP to 11 and macOS 10.12 to 27.x on its US spec page, but Windows 7 to 11 and Mac OS 10.12 to 12.x or later in the datasheet. Its quick guide pictures a USB cable and AC adapter and says contents vary by country, and its software is a download. Epson's full US packing list was not verified in the reviewed source.
No standalone destination is documented. It connects by USB 2.0 to a Windows or Mac computer, and DocAction Plus, MacAction or a TWAIN application on that computer receives the scans.
