can one print at actual pixels size?

Can one print at actual pixels size (100 %)? How is this done?

Kibo informs me that nobody nowhere stated
that:

Can one print at actual pixels size (100 %)?

Of course, as long as you don't mind cropping your your image, or you
have access to a big enough printer. You can go bigger too. I've printed
a number of my 10D (6.3MP) photos at 10"x15" & 400DPI, which is roughly
400%.

How is this done?

Depends on the image, the software you have, & the printer.

If you explain what you're trying to achieve, we can probably give you
response that are much more useful than this one.

Can you rephrase that question? A pixel will have whatever size you print
it, or do you mean printing at the same size as the sensor?

If you mean "can you print so the print is the same size as what's on the
screen at 100%" (which is what I *think* you mean), then yes, you can do this
IF you can figure out the rez of your screen.

Many older monitors have a dot pitch of 72 dpi (which is why that's a common
default number in many graphics programs) and many new ones are around 96 dpi.
So I'd try setting the image size rez at one of these numbers and printing at
that size, but the print will be really big. Note that most printers like
200-300 ppi input file rez so the print will be pretty thin and low rez for,
say, the Epson desktops.

To put numbers on this, a typical 6 Mpixel dSLR file might be 3,072 x 2,048
pixels (for the Canon 10D, say). Set the resolution to 72 ppi and it will
print 28.444 x 42.667 inches, set the rez to 96 ppi and it will print 21.333 x
32 inches, set the rez to 240 ppi (enough to get a nice print on most printers)
and it's 8.5 x 12.8 inches.

hmm this is or appears to be an extension of what is a pixel?

A pixel is a picture element

A printer pixel is not the same as a monitor pixel and both are not the same
as a sensor pixel (sometimes called sensels)

A monitor relies on physical attribute of light - usually called additive
which combines 3 primary colors to obtain "white"

A printer (usually) relies on subtractive properties of inks so comining a
combination of all 3 inks produces something called "black"

See the difficulties?

What is intended is bto have 1 to 1 correspondence across the physical
properties of each device in order to render an accurate image. The image
will always be subject to the constraints of the physical limitations on the
hardware, software & drivers in place.

Plus - there is the aspect of human perception. While eyes allow light to
excite receptors the brain interprets these signals into an image.

Now the above is a gross over simplification. What was the question?

Oh - yeh. It depends upon having the correctly configured hardware,
software firmware. After that it's easy within the constraints listed above

ps - seel Gisle's link below for even deeper reading on the effect called
interpolation

it's sorta important and for any budding mathematical genius out there -
yeh, it really is all math

A pixel has no size. So - no you cannot print at pixel size.

Hmmm .... methinks you are trolling?

Most pixels have a finite and well-defined size - can you quote examples
where the pixel has "no size"? Of course, printing at the original pixel
size may not be quite what the OP wants!

The way I do it is:
Adjust the image so it looks the way I want it (Photo Shop or Elements)
Save it in TIFF on the Desktop
(on the machine connected to the printer) (Epson 750)
Open it in PSP on the printer machine
Tell PSP to print it
Use PSP's screens to
Choose paper and output mode
Fit the image to the paper
Push Print
PSP chews on it for a while, sends it to the printer
(Quite a bit later)
It comes out looking just like it did on the monitor

Lucky (simple) me.

The pixels stored in a file has no size.
A pixel as a concept has no size.
The pixels in my graphic card has no size.

A pixel can be matched to something that has
a size, e.g. a sensor, a monitor or a print.
You often also call this physical realisation
a pixel, but this is misleading.

Of course, printing at the original pixel
size may not be quite what the OP wants!

Yepp - and this (probable) mistake shows that you
shall think of a pixel as having no size.
