Here is a TidBITS article by Joe Kissell on an issue in Apple's Mail program in Mountain Lion.

The issue has to do with a change in sending from which account behavior.

There are a number of open source printer drivers which will allow you to use just about any printer with OS X (although not all features may be available):
SpliX
http://guigo.
GutenPrint
http://gimp-
OpenPrinting
http://linuxfoundat
One of the great things about OS X is it's Unix foundation, which gives you access to a huge number of free and open source solutions that you won't find in places like the Mac App Store.

On a whim, I converted (using Preview) a JPG file that I had pulled from Wikipedia to a PNG file. A side-by-side comparison of the two pictures showed no difference. The PNG file size was about fivefold greater than that of the JPG file.
Per http://en.wikipedia
My thought is that there is no plus in converting a JPG to a PNG because the conversion process can not (it seems to me) improve the original file. That said, something must have happened to have created a five-times-larger file. Perhaps I'm mistaken.
Interestingly, my camera takes JPGs and my laptop takes PNGs for its screensnaps. The latter ones that I end up keeping I retain in the PNG format. If I send any via email, I still use the PNG format as most emails can handle the extra weight.

You are right: JPEG is a lossy format and the losses have already happened.
You cannot restore those by converting to a lossless format. Also, if you
edit and save a JPEG, you get further losses each time.
So it's only worth converting to PNG or TIFF if you plan to edit the image
and want to avoid further losses.
This is exactly analogous to MP3 and WAV/AIFF in audio. You can convert an
MP3 to a lossless format but you are not adding back any lost information,
just making a bigger file.

It's five times as large because that's the price of having a lossless image file. The original image cannot be improved however it's converted. The advantage of converting to to a lossless format is that the file can be opened and re-saved as often as you like without losing any further quality.

Anyone know how to tweak OS X (Lion) to save screen captures in a JPEG format instead?
Thanks,
Dane

Heh. Decided to Google it and found it's pretty easy, using either the Secrets pref pane or a Terminal command:
defaults write com.apple.screencapture type jpg
I tend to use Jing for my screen captures (and have no idea how to edit those settings) but at least now when I do a standard OS X capture, the resulting image is about 1/5 the size it used to be.

I think Bluetooth devices need to pair so others can't access your iPad
without your consent, but there is something called "Bluejacking". Even
this isn't too bad, though, because the other person can only send you
stuff, not read anything on your device.

Sorry if I was misunderstood I was looking for a ADF like thing which can scan a set of 10 photos at a time (one by one ). I will look into the Epson suggestions Thanks
