As a follow-up to my problem testing printers, I tried things again.
The files were re-created and put on an msdos flash drive. When the
usb drive is placed in the slot of the 8610 (or Epson WE-3640), the
devices recognize the number of files on the drive, but claim they are
corrupt and won't print them. The sales person tried the drive on two
different computers, and the files were fine. Any ideas?

Dave,

There is no such thing as a "MS-DOS Flash Drive". In fact they did not
exist when MS-DOS ( Microsoft ). PC-DOS ( IBM ) or DR-DOS ( Digital
Research ) were the Disk Operating Systems. You mean FAT16 or FAT32
Formatted drives. That goes to what I wrote on 2/4/'16 that some
printers require a FAT formatted devices and won't accept a NTFS
formatted device.

You are going about the problem from the wrong angle.

While some printers can indeed print some graphic files off of USB
Read/Write Media, that not the best way to go and yo\u shouldn't even be
thinking about Document Files such as PDF. One should look at a printer
that has a flat bed and/or Automatic Document Feeder ( ADF ) scanner is
see if the software provided is capable of scanning into a PDF.

The best way to print any form of graphics or documents is with a
computer. The software on the computer can render the content properly
and can best format the print job as you need it.

"A little off topic, but when will printer manufacturers get a clue and
make all printers that accept jpg's, tiff, png, pdf, open document
(LibreOffice), and MS Office files natively? This would eliminate the
need for printer drivers. "

That NOT the way it works and especially for the retail market devices.
That's role of a computer, not the printer.

It is not the manufacturers that need to get a clue.
You need to understand these concepts.

What I understand is that printers used to have post script interpreters
in them, and pdf would be no harder. FWIW, I'm not looking for a cheap
printer, which you don't seem to grasp. This is a printer that will be
used by Linux, Win xx, and Apple computers. So, yes, I do expect better
than I have found.

As for testing printing, the use of a scanner is nuts. Duh!

Dave,
