The HHP IT3800 and/or 3900 are very common in self-checkout configurations for Evergreen ILS.
This document describes how to configure that device is a common setup. A modern Windows based PC, Keyboard Wedge, Quiet, Slow Scanner.
Reset the Scanner
Configure for AT PC, with Carrige Return suffix.
Configure for Self Checkout
Scanning Rate
Use the Low Power scan rate, 67 samples per second
Beep Volume and Length
We set this to quiet and short
Scan Delays
Configure a medium delay on good scans, long delay on duplicates.
Auto Scan & Presentation Mode
Automatically scan the codes, no manual trigger needed; presentation leaves the lights off until a barcode is presented.

Wireless Scanners
Try the wireless Honeywell 3800g.
Realistically, ANY scanner that acts like a keyboard, can scan your barcodes and can be programmed to do a carriage return after scanning the barcode will work just fine. Unlike some other ILS software, Evergreen is not picky.
