kprinter cli and preview

[Thomas Friedrichsmeier]

Hi,

this issue has come up before. A quick search in the list archives, for 
example, showed up a thread from 2002 
(http://lists.kde.org/?l=kde-print&m=103661712527872&w=2).
The problem is, kprinter does not offer a preview when invoked from the 
command line. As far as I understand this is, because it can not be sure, 
whether the input is PS.
Now, most of the time, when using kprinter, I do indeed want it to print some 
PS input, and a preview option would be nice. One suggestion in the thread 
referenced above, was to add a command-line option along the lines of 
"--trust-me-input-is-ps-enable-preview-i-know-what-i-am-doing". This was 
turned down since a more generic approach was said to be in the pipe.
Well, this discussion took place more than two years ago, and the problem 
still exists. If the generic approach has proved problematic, could we have 
the command line option as a quick solution, please?

Thanks!
Thomas
