Hello joncanfield, if possible, I would like a counsel from you. At first, I must tell you that I have recently began working with a 44" HP z3200ps printer connected to a MacBook Pro (with Mac OSX Leopard Snow). Nevertheless, seeing that I would like to print very big posters by tiling pictures, I would like to buy a RIP to do so. Someone offers me a software EFI Designer RIP 5.1 XL as you had with your HP Z3200ps printer. Therefore, my question is: since this EFI Designer RIP 5.1 was made for HP z2100 and HP z3100 printers, does it work 100% very well with a Z3200ps printer which is somewhat different in relation to the Z3100 HP printer ? (eg. the HP z3200 Management color has changed seeing that some of the 12 inks have been modified: red and blue have changed in the z3200). So, please, tell me if that EFI Designer program is worth buying although it has been replaced by EFI Express Color for Proofing Advanced 4.5 (if I am right). I thank you very much for your precious help and counsels. Sincere greetings to you all.
