Please try the following then
Rename the folder named QuarkXPress 6.0 to OLD QuarkXPress 6.0 at the location below:
My Commputer//C drive//Documents and Settings//Your Usre//Application Data//Quark//QuarkXPress 6.0
Also make sure that the no folder with the name Preferences should exist at the location below:
My Computer // C drive//Program files//Quak//QuarkxPress6.0
Now relaunch the application and then try printing it.
Step 2: Try printing only the second page rather than printing all of them together.
Step 3: If still it doesn't work Go Utilities >> Usage >> Fonts and then replace all the fonts with the font Arial ; click Done:
And then try Printing the problem file
I hope this will help
