I would look for any printer with a scanner that has a feeder on it. Business class scanners will do scanning on both sides of a sheet - Epson look to have a good range, but I’ve found the scanner on my Canon printer does the job admirably and I rarely have double sided documents to scan.
I have been using Fujitsu ScanSnap iX500 for 15 years, never give me any issue. I believe they now have a newer model but overall based on same technology
FUJITSU IX500. No doubt. I still use ScannerPro and SwiftScan Pro for one off scans on the go. But if I have to scan for archival I use the trusted ScanSnap and OCR it.
I have been quite pleased with my ScanSnap iX1600.
I understand some people felt abandoned by ScanSnap in the past, but I decided to take a chance and I’m happy with the results.
The first thing I did was scan 20+ years of tax returns and documentation; each year was easily over 50 pages. The process worked flawlessly.
For the OCR functions, you will want to read the documentation. At first, I felt there were a lot (too many) of working pieces, but once I read the manual, the OCR functions work great.
I don’t notice any real speed differences when using WiFi scanning rather than via USB.
Have a look at the Brother DS range of scanners. They’re similar to the Fujitsu but quite a bit cheaper (about half the price of Fujitsu here in the UK).
If you’re using DT as the scanning software, you won’t really need the extra functionality (and maybe hassle) that the Fujitsu software has. DT should just use the Apple ICA
