First of all, I don't know how I can disable hyphenation (with Adobe InDesign it's quite simple, you have just to flag a box in the text window), but I can't find anything similar in Quark and I really don't know how I can proceed (because I don't want hyphenation).
Edit > H&Js > select the style, click Edit button > uncheck the Auto Hyphenation checkbox > OK > Save
Then I can't trasform a .qpx file into a .pdf - I've been searching on the web and it seems the only way is to use Adobe Distiller (while with InDesign, you have only to press a button - and it's clear indeed because they're both Adobe products). But I was guessing if there are any alternative solutions (I don't have Distiller).
I guess you can use any printer driver that produces the PDF files. Personally, I always print to PS file and then use Distiller.
