*New Updated Method at the end*
A few days ago I was lookign for a document and found it on Scribd. I wanted to print it out but I needed to register, upload documents and wait 24 hours or pay a fee to get access to their database and be able to print. I started looking for a way to bypass it and found a nice tool online coded by Samar Dhwoj Acharya.
His “Scribd Document Downloader” allows you to download any document hosted at scribd without having to register for an account or paying. The script is pretty straight forward, copy the scribd link and paste it in the box and click download.
The script can be found here: Scribd Document Downloader
Hope this helps. Enjoy 
Update 9/8/12
Thanks to all who reported that the site was no longer working. Here’s a new working method.
Requirements
- Google Chrome
- Chrome user-Agent Switcher
- Visit the “mobile” version of Scribd
Step 1
Once you have Chrome installed along with the Chrome user-Agent Switcher, visit any scribd document that you want to download. In this case let’s say i want to download this solution manual:
http://www.scribd.com/doc/68485796/Calculus-of-Variations-Solution-Manual-Russak
From the link, all we need is the id, in this example the id is the folllowing 68485796 which is found …/doc/id here/….. in the link above.
Another way to find the id, in case Scribd updates its system again, is by viewing the source of the website (Ctrl+U in chrome) and searching for “doc_id” and the id will show in this format:
“doc_id”:id here as shown below:
Step 2
Visit the mobile site of Scribd, which is http://www.scribd.com/mobile/
Step 3
Change the user agent to Android using the Chrome User-Agent Extension as shown below:
I tried iPhone and it didn’t work for me, so make sure is Android.
Step 3
Search for the id, there should only be one result (unique id), and click on the result. Once you click on the result, a download button will appear and now you can download the file.
Update 9/16/2012
Once again it has stopped working. I’ll see if I can come up with a way around. As of now this is what you can do:
Download and Install FastStone Capture, once installed use the ‘Capture Scrolling Window” feature and save the file as a PNG or JPEG. From there you can print the image file as a PDF using Adobe or CutePDF Printer. This only works for the documents that are shown in “full” and not just a “preview”.
That websites does not work anymore, it stopped working after Scribd updates.
Try now, it has been updated.
Doesn’t work
Please Update Latest Site. Above site is no longer works
Thank you! The new update works!
Thanks but unluckily it does not work anymore, any news ??
I can honestly confirm that this has been a problem on my end lately and the download button using the User Agent Switcher is gone -_-
Those assholes at Scribd must have known about the workaround and found a way to block it. AAAARRRRRGGGGGHHH!!!!
If there will be no new methods I suggest to boycott them for good. Otherwise if there are documents you must get hold of and read locally without a constant internet connection maybe you can try and negotiate with some of the users and uploaders there to upload their docs into either Google Docs, or some other 1-Click Hosting site such as mediafire, rapidgator, rapidshare, etc.,…
