Hi! After a lot of work without any problem, now I am not able to print some files. The problem is the same both for Pepakura Designer High. Res. and for Pepakura Viewer for CraftRobo. Different files (having the same size: about 430 Mb), generated from different parts of the same metasequoia model, behave differently: some can be printed, some others cannot, causing an unexpected escape from the program. OS: Windows 7 Printers: Epson Stylus DX4850, HP OfficeJet 7500A Wide Format Software: Metasequoia 2.4.13, Pepakura Designer High Res. 3.0.7a, Pepakura Viewer 3 for CraftRobo 3.0.3a Thanks for your help!
