Gian Luca Mora, technician at Zenit Informatica in Novara, tells us about a small but inconvenient Jaguar bug in the configuration of Apple printers. "The problem that occurs when any model you choose the Print Center always uses the generic driver, and I after a few reports of customers who could not configure them I investigated why the result of this verification that if you are trying to configure the printers as admin or general users he does not disturb the PPD, which compressed in .gz format. enough to write to that directory the software always manages them as generic drivers.
The solutions, pending an Apple bug fix, are four: here they are in order of comfort.
1) Log in as root user, go to the folder "Macintosh HD / System / Library / Printers / PPDs / Contents / Resources / it.lproj" and once you unzip them all the files and delete the .gz after unpacking (so whatever apple printer you use there are no more problems).
2) Move the first compressed files from the "Macintosh HD / System / Library / Printers / PPDs / Contents / Resources / it.lproj" directory to the "Macintosh HD / Library / Printers / PPDs / Contents / Resources / it.lproj" directory "
3) Remember to always configure apple printers by the root user
4) Change the privileges to the "Macintosh HD / System / Library / Printers" folder and all those contained in it, but better not to play with the privileges in the "System" folder "
