Sorry, I can't post more than one hyperlink due to my limited rating, so you'll have to Google for the links. gscan2pdf A really good GUI system that can use various OCR engines for the backend.

This blog had the best documented suggestion of the simple and sweet iCopy. I tried all the others and many more, and only this worked flawlessly. I already have used CutePDF free for a decade which acts as the "to pdf" converter after you get your pages all scanned in with iCopy.
I've used this command for %%i in 200 to 254 do ping 10.1.1.%%i in a batch file for a similar reason
Scan them at a high enough resolution that you'll never need to scan them again. i.e. "archival" quality. I'm assuming the old photos are important and you want to keep them for a long time, and view them both on screen and perhaps re-print later. Generally, space is cheap, but your time isn't. I suggest 600dpi minimum, and more if you can handle it. ...
its old school, but put a sheet of black paper behind the newspaper. A lot of the issues are caused by the fact that newsprint is thin poor quality paper. The scanner sees the front and the back of the page at the same time. Black paper matches the black ink and makes the "back" side of the newsprint disappear.
A quick fix I do is to compensate for the low quality paper and printing, by adjusting the 'white point' and 'black point', efectively increasing the overall tonal contrast of the image. Looking at your first example, the lightest parts of the image -- unprinted paper -- are actually a light grey and the darkest -- 'black' ink -- are a mid grey. And there's ...

Is PDF very inefficient? Not particularly, as your comment to the Q shows: 'cos the PDF of 10 greyscale pics, is 6.35MB! It all depends on the resoution and level of compression. Fundamentally the answer is: full pages are quite large and typical scanning and printing resolutions are quite high: thus lots of data. Basic calculation: A4 is about ...
The music program Sibelius is good at this sort of thing. They have a package called PhotoScore Lite that will let you scan in sheet music, and turn that into a MIDI composition that you can play within the Sibelius music editor. You can find it in major music stores. The learning curve might be a little bit steep. I'd recommend asking the person at the ...
While the other answers, such as scanning at 600dpi, are generally true, if your scanner is of a low quality, you might not be actually picking up any more detail. Compare the different sizes. Zoom in, look at the details, try a few prints. Show them to a photographer friend if need be. If there isn't a worthwhile difference, don't worry about it. 150dpi ...
Here's the problem: slides are intended to be viewed by putting light through them from behind. Your scanner is trying to bounce light off the front, though, which just doesn't work well, resulting in terrible color. What you need is a scanner with a piece of hardware called a Transparent Media Adapter or TMA. A TMA is a cover for the scanner that has a ...
I want to suck out the highest quality from that scanner, but is there a point in scanning white paper with black ink at such a high color depth such as the 48-bit that is the max on my scanner? The shorter answer about color depth, DPI and document scanning: In short? There is 100% no valid reason to scan white paper with black ink at such a high ...

Since you have Adobe Acrobat X Professional, you should be able to use the "Print to PDF" option. All you would need to do is "Print to PDF," and make sure that the paper being printed to is letter format (8.5" x 11"). Page scaling options should be under the printer setup menu in the print dialog.
To answer how many bits of color depth you need and how it affects your results, let me start with a quick explanation of what color depth actually is. What is color depth? Color depth describes how many shades of color will be stored. If an image has extremely fine gradations of a color, scanning and storing an extremely high number of colors means that ...
It's fairly tricky to scan halftone-dithered images from newspapers without a bit of background as to what's going on with the dots. I suggest you have a look at this article. For best quality, you basically choose the right resolution (the same as the print) and scan using a descreening filter (often available in your scanner software). You can then apply ...
Try CuneiForm or Tesseract (currently developed by Google).
Given that the OCR has converted: Als Arbeitsmarkbehörde ... to: AlsArbeitsmarktbeh6rde ... A couple of things spring to mind. Try scanning at a higher dpi. It looks like it can't recognise the space between the words, a higher dpi might improve that. Can you set the language of your OCR program? I see that it's converted the "ö" to a "6". ...
