The Arabic version of the LaserWriter Select 310 print driver is not a requirement for using the printer with Arabic System 7.1. Compatibility with the UK version of the print driver is not known, however, the international Z-version will work with the Arabic system.
Essentially, the localized print drivers such as the Arabic version contain localized strings (Page Setup and Print dialog boxes with Arabic instead of English words), installer scripts, and paper size selections available in the respective country. The Z-version has English strings for the user interface, though contains the region-specific paper size selections, as well as modified installer scripts to accommodate the various script systems.
