You need to install a PDF writer program first. There are quite a few freeware PDF writer programs on the Internet you can download one such as CutePDF.
Scan your document the click on File - Print and select the PDF writer as the printer device. Then name and save the PDF file.

When you scan them, save them as a different type of document. Try saving them as a web document. They will reproduce almost as good and will be a lot smaller in size (bytes, not inches).

Hi,
Check for the Save Options in scanner settings. If it is in .GIF or .TIFF format the file size obviously increases.  If you change it to .JPEG format it reduces to around 900kb.

The scanner produces a "picture" of the document, much as if you laid it flat on a table and took a picture of it with your digital camera. If you did this, your .jpg from the camera would be several hundred K at a minimum - comparable to the file size off the scanner. That's why the file is so big, it contains a picture and not text data - even though it's still a .jpg file.
If you reduce the scan resolution you will save space, but at the expense of legibility of the document image. To get it down to the smallest possible size, you will need to run the scanned image through OCR ( Optical Character Recognition ) into a Word document for example, and then print it out to a .pdf file. If you have a clean source document with few graphics this isn't as difficult as it may seem. Microsoft Office has an excellent OCR process known as Document Imaging. You need to carefully proof read the result but with a clean input Document Imaging is amazingly accurate in Office 2007.
In short, there is no easy solution to your problem.

I'm using an MP780. Usually when I scan an image to jpeg I press START, CANON, SCANGEAR STARTER. This open a window to ScanGear MP. Since I use the Advance Tab I can set the DPI and whatever outputs. The DPI rsolution will determine the size of the file also. When it is finished scanning it goes to the next window which has Save As Type and Save Scanned Image to. Save As Type is where you can choose JPG or TIFF or BMP. Hope this helps.

If you have installed the software of the printer already then you can use the hp solution center to scan a document or a picture. And make sure that you have save the picture or document. After saving it to your computer you can open your email and put the document or picture as an attachments
