Basically, `tex-view` works, opening Evince, on a compiled .pdf only
after a .dvi is created.
Running 'emacs -Q' I evaluate the following in the scratch buffer, to
make it so that latex is compiled to pdf:
```
(setq tex-print-file-extension ".pdf"
tex-dvi-view-command "evince"
tex-dvi-print-command "lpr")
```
the last two lines are following the instructions on the description of
`tex-print-file-extension`.
I navigate to a simple .tex in an empty directory and press `C-c C-c`
which is bound by default to `tex-compile`, I press enter, as the
default is `pdflatex`, and the file compiles, creating a .pdf in the
directory. After that I press `C-c C-v`, which is bound to `tex-view`
but Evince does not open, instead I get the message "tex-print: No
appropriate ‘.dvi’ file could be found. If I press `C-c C-f`
(`tex-file`) after that, a .dvi file is created, and now `tex-view`
works, meaning it opens the .pdf with Evince.
The fact that `tex-view` works on the .pdf only when a .dvi is first
created seems like a bug.

Thanks. Can you step with Edebug through tex-print in your case and
try to figure out what happens there that causes the error message?
There's some logic there which is supposed to verify that the current
buffer's print file is up-to-date:
(if (and (not (equal (current-buffer) tex-last-buffer-texed))
(buffer-file-name)
;; Check that this buffer's printed file is up to date.
(file-newer-than-file-p
(setq test-name (tex-append (buffer-file-name)
tex-print-file-extension))
(buffer-file-name)))
(setq print-file-name-dvi test-name))
Maybe something goes wrong there in your case?
(I don't have the requisite tools installed to try this myself,
sorry.)

I debugged this and the problem is that tex-print expects the variable
tex-print-file to be set, but (as its doc string says) it is set by
tex-region, tex-buffer and tex-file, which are all not commands run by
tex-compile, which is meant to run external programs (listed by
tex-compile-commands). A simple fix is the following patch:

But I'm not familiar with the tex-mode.el code and don't know if this
change might have unwanted consequences (though it seems prima facie
safe).

Thanks.
Stefan, do you agree with this fix?

No objections here.
Personally, I use `C-c C-c` to view the PDF (i.e. `C-c C-c` first to
compile the TeX file, then a second time to view the result).
So, maybe the patch below would also help.
