[Scribus] prepress RIP

[bart at solozone.com]

I inquire as to the use of pre press RIP in Scribus. I think this may have been discussed before but my colleagues in wondows are discovering that Quark needs RIP for good results in Windows and they are all dizzy with Harlequin pre-flight and such. I do not myself use high end printers or wide format or image setters but others do and I would like to advise soundly.
TO print in Scribus is there significant difference between its printing or export to pdf or RIP? IS RIP used in Linux at all?
