eBooks normally use digital rights management, which is a complex and expensive process to set up for yourself. Adobe's DRM software is part of the LiveCycle server suite, it cannot be done with Acrobat alone.
Acrobat can apply a 'permissions' password to a PDF file which requests that printing is disabled, but only Adobe software is guaranteed to respect that request. Many third-party PDF reading apps will print it anyway.
Thanks for the information. I have a number of publications that I wish to apply DRM restrictions to. I must now look at where one may obtain suitable software.
