Which printers print directly from RAW?

all of them.

Proof?

open raw image. choose print from the menus. collect print from printer.

optionally adjust image prior to printing.

Are you saying there is no conversion prior to printing.

obviously the printer driver converts the data to whatever format the
printer needs, but that isn't anything that the user sees nor needs to
be concerned about.

whatever software you're using also converts the data to its own native
format. your camera isn't spitting out .psd files.

the user simply opens a raw image, adjusts to taste and prints. done.

they do the same thing with a text file, spreadsheet, 3d graphic or
whatever else. just open the document, adjust if desired, choose print
and collect print.

the point is there is *no* need to save as a jpeg or any other interim
format to print.

So there is a conversion. Once there is a need for conversion, it is
immaterial whether the user does the conversion, or an activated app
does the conversion.

nope.

once again, you're trying to argue for the sake of arguing.

the raw image is converted to pixels on the display and nobody
considers that a conversion. the magnetic fields on the hard drive are
converted to electrical pulses and nobody considers that a conversion.

there's a conversion with *everything* on a computer.

the printer is just another display device that uses paper instead of a
liquid crystal (or crt). apps draw to either or both and may not even
know the difference.

again, the user opens a raw image ...

Opens a raw image in what?

Whatever software you are using. In our case that should be Lightroom.

... (or whatever format, it doesn't even
need to be an image) and picks print and the computer does the rest.

that is not a conversion.

Of course it is.

Your statement is contrary to other comments I have heard.

then you're listening to ignorant people.

Leave out snarky comments.

i'll say whatever i want.

Your attitude adds to your persona. You have a sick and desperate need
for attention. Looks like you have to keep convincing yourself of your
greatness. Too bad others are not so convinced.

the fact that you're resorting to insults shows that you have nothing
whatsoever to refute what i'm saying.

as i said, you're trying to argue for the sake of arguing, and it's
failing.

I don't think you are right about this.

Like me, PeterN is trying to find out how it is possible for a printer
to swallow a raw file and spit out an image. My understanding is that
this is not possible. You seem to be supporting that view by extending
the argument to 'conversion'.

Go to Lightroom and select any NEF or DNG you have available. If you
want to make whatever adjustments and edits you choose to (including
aspect ratio crops) in the Develop Module, or not.

Next go to the print module and you will find that you should have
little trouble printing that NEF, or DNG, all without an intermediate
JPEG phase. As I said I don't have any JPEGs in Lightroom.

As to what Lightroom does as an intermediate phase I have no idea, as
it doesn't leave any evidence of sneakily creating a JPEG without my
knowledge.
