Hi Peter,

Many thanks for your answer. I opened the console and found out that the *are* indeed 
errors (the log is appended). I'll use the terminal and let you know how it works.

Cheers,

I suppose there must not be a bug in QtiPlot, because the printing  
system has another programme to convert PS or EPS to PDF ... The  
reasons why TeXShop can fail are a few.


Have you /Applications/Utilities/Console.app running? If TeXShop sees  
an error it will report it in Console.

Are you experienced with the command line in Terminal? Then you could  
try to use the supposed printing system's convertor, it's like:

	/System/Library/Printers/Libraries/convert -i application/postscript  
-j application/pdf -f "best complete path to EPS input file within  
double quotes" -o "best complete path to PDF output file within  
double quotes" -P <path to PPD file optionally>

The sequence that starts with '-P ...' is optional. I am not  
completely sure whether the path to the 'PostScript Printer  
Description' (PPD) file is necessary in any case. You can make your  
life easy when you just type the command until the first double quote  
and then drag&drop the file from Finder onto Terminal. Check whether  
spaces in this path name where 'escaped' by \ and remove these  
backslashes. Finish the input file name by typing a double quote  
exactly at file name's end (by dropping the file on Terminal  
automatically a SPC is added) and continue with ' -o "' and drop  
again that file onto Terminal and filter its name from backslashes.  
Now remove the file name's extension and substitute it with pdf.  
Finish with a '"' and a <RET>!


You too can try to convert à la TeXShop: 'pstopdf <EPS input file>',  
optionally you can add the PDF output file's name. pstopdf can work  
in Terminal when you first type 'pstopdf ' and then drag the EPS file  
from Finder onto Terminal and type the final <RET>. By default the  
PDF output file will be created in the same directory from which you  
dragged the EPS file. A possible cause for an error can be that this  
directory is not writable ...
