Again, as I've mentioned to Max Peter previously, this is one of those obvious things to chack and eliminate before getting on to a forum.
What my curiosity has turned up is that on a standard lower res setting it prints ok, but higher res and better paper [archival matte, watercolour paper, gloss] all print bigger. Given that the print settings arte the dsame except for resolution and paper type, I'm baffled.
I've tried a file on earlier versions of Quark - v.6, 7, and 8, and the same problem occurs.
By the way Max - yes I have done pdfs from Quark and these printed as they should, so it couldn't be the printer driver or printer description file if CS4 use the same printer files ..... could it?
Thanks for your time and comments
