You can print pages from a Kortext eTextbook.
Once you have opened the eTextbook on your screen, there is a printer icon 
on the left hand side toolbar.
However, UK copyright law states that you can only print 10% of the book or a chapter, whichever is the greater amount. The Kortext eTextbook will state how many pages you can print altogether.
Please note: that you can treat a Kortext eTextbook as your own personal copy for the duration of the module you are studying or for the research that you are undertaking. You can read online, take a break and read some more and access will always be available to you.
