I have just started working with Ubuntu for the last 10 days, with the intention to stop using Windows permanently. So far it has been awesome. I have replaced almost all my Microsoft applications with available Ubuntu apps and some help from Google Docs.

I am experiencing a problem with my Canon CanoScan LiDE 110 Scanner. When I use the scanner in Windows 7, and saved scanned pages of a book as PDF, I can open the PDF scanned page and copy text from it directly to paste at Google Docs or any LibreOffice document. I tried doing the same in Ubuntu using the Simple Scan app. I scanned the page as text in Simple Scan and saved it as a PDF. However in Ubuntu when I open the scanned PDF page, it opens OK, but I cannot copy the texts.

This is quite important for my workflow, as I am a medical physician and I need to study a lot of books.

I would really appreciate it if you can help me with this.

Hello Aditya,Hope you are doing well. Thanks a lot for your lead. I have started using Tesseract. Well, in another article i read that Gscan2pdf offers the option to select the OCR, and Tesseract is an option. I tried that ... and wow ... the text recognition was much better than the previous method I was using in Windows. Thanks a lot. One more step closer towards getting completely out of Windows. I tried to vote up your reply. But I do not have enough reputations. regards. –  learner Mar 17 at 3:53
