When I first bought a piece of equipment and only a manual on CD was supplied, I longed for the printed version. As with other things times have changed, perhaps for most people for the better.
Now if the pdf version of a manual is not supplied, I go to the manufacturer's web site to see if one is available. Usually there is.
How PDF manuals can be better than printed versions.
* All the PDF manuals for your equipment can be recorded on one CD/DVD or so, or kept on your computer or external hard drive.
* Copy the PDF manual from the manufacturer's CD to your own preferred location.
* All the manuals for all your equipment, computer, entertainment, tools, etc. are easily available from your preferred location.
* If you use Dropbox or similar service they are available on any piece of your equipment including iPad or phone.
*No searching through file cabinets, piles of paper or whatever - all your manuals are in one place.
* If you have a laptop computer, or iPad, you can have your manual right beside the product you are working on.
* You can go right to the section of the manual you want by using menus and links that are usually built in to the PDF version.
* Extra resources are available by clicking on the links supplied in many PDF manuals, including updates.
* If you need to help a friend with their problem, take the manual with you on a USB jump drive or access it with Dropbox.
* If you are going on a trip, take the manual with you for your computer, GPS, cell phone or whatever electronic devices you carry with you.
* Many printed manuals these days are written in mini-print that you can barely read. Using PDF you can enlarge the print with your reader to whatever size you are comfortable with.
* PDF manuals are easier to read. If you need the steps for programming a remote control or need to see the terminal connections for your cable box, you don't have to try and hold a tightly bound mini-book open and manipulate the controls at the same time.
There are many more reasons. I am sure if you give it a try you will soon agree PDF manuals are more valuable than it first appears. Not only that, if need be, you can always print out a page or two, or a diagram if that is your need. Don't print out the whole thing though, that defeats the purpose.
It takes a little practise, and sometimes a change in attitude to adapt to new ways of doing things. In this case it is worth it.
A Google search will help you find PDF manuals you want for practically anything you own, often for free.
If you have a paper manual for your equipment, why not scan it to PDF format and save it to your preferred location so you can find it when you need it.
