In the NSPrintInfo documentation, when talking about the printSettings, it says:
"Adding keys to the dictionary is equivalent to calling the Core Printing
function PMPrintSettingsSetValue. Your new keys are added to the current print
settings and are saved with any user preset files generated by the Mac OS X
printing system. Because the print settings are stored in a property list, any
values you add to the dictionary must correspond to scalar types such as
strings, numbers, dates, booleans, and data objects or collection types such as
dictionaries and arrays."
I took this to mean that so long as I store my own custom settings in the
printSettings dictionary, then if I used NSArchiver and NSUnarchiver to save
and restore the NSPrintInfo object, that my custom items would be stored along
with the dictionary. It appears this is not the case. If I set some custom keys
in the print into printSettings, then do the following:
NSPrintInfo *oldPrintInfo = [self printInfo];
NSPrintInfo *newPrintInfo = [NSUnarchiver
unarchiveObjectWithData:[NSArchiver archivedDataWithRootObject:[self
printInfo]]];
My oldPrintInfo printSettings has all my added keys, and the newPrintInfo has
only the standard keys.
I want to save my custom keys with the print info, and the documentation says
that this happens when it is stored by the printing system, so what do I need
to do to be able to save it in my document?
I realize that I could archive printSettings separately and re-populate the
printinfo, but that seems pretty messy when the documentation says explicitly
that there is a way of storing it so that the custom attributes are preserved.
Thanks
