When asking a computer scientist, I received a clear answer: does not exist. However from a legal perspective, "printed computer programs" do exist and a can be chosen as a class for CTM registration.
So what is a printed computer program?

Why don't you ask your computer scientist how he would describe what comes out of the printer when he is looking at his computer program and presses "print"?
For the purposes of the law you cite, that is what it means.
Edit to address comments
The computer program stored in an electronic format is covered by a different section of copyright law (also referenced in the case you cite).
When the source code is printed then there is copyright in the printed source code. Alternatively, if a procedure was written by hand with a pencil and paper (i.e. never stored electronically) there is copyright in that; not that such an event is likely. Copyright exists in both the text of the program and the presentation on the paper; there could be circumstances where the presentation is important although I can't think of any. Copyright does not exist in the algorithms used - these may be patentable inventions but they are not protected by copyright, only the "literary work" aspect of a program is copyright.
In the case of the web browser presentation and the 3d-printing of a chair - neither of these are computer programs; they are the output of a computer program. The browser presentation is a "literary work" in its own right and covered by copyright. The chair is not a "literary work" and does not have copyright protection but it may be a registrable design.
In order to be "copyrightable," a work such as a computer program needs to be "fixed in a tangible medium."
One way of doing this is "printing it out." Another way is "saving it to a disk" (or hard drive).
A program that is written and not saved to anything is not copyrightable, because it could be lost, along with all evidence of authorship.
