Welcome to the forum Neil.
Personally I wouldn't use a template for a CV. There's so much text that you need to add that the extra work taken to add your own text frames into a blank document fades into insignificance.
As for the problem you're having, it could be almost anything:
* Does a change in font make a difference? It could be a dodgy font.
* The template could be designed badly. Are there any layers containing stuff you don't know what it's for? Are there any frames or objects that don't have a reason to be there?
* Does the text contain any unusual character strings? They might be hidden if you've copied and pasted from a file that isn't plain text.
* Your printer driver could be faulty. Do you have the correct and up-to-date version?
* Have you got the latest version of Acrobat?
* Are you using a stable version of Scribus? 1.4.6 is the current recommended version.
Normally I'd ask for you to attach the document with the problem in it but as it's your CV - containing all sorts of personal information - that's probably not a good thing to do.
