Re: TPostScript, empty pages are created in between real pages

 Hi,

 I cannot run your example because, as you said, it is not a complete one. But looking at I gathered you would like to generate several outputs in the same file. In that case why don't you use the "parenthesis mechanism" described here: http://root.cern.ch/root/HowtoPS.html ?
