USB file formats for HP and Epson

From: "Dave Boland"



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.
