// The code below is borrowed from the CUPS 2.2.x upstream repository
// (via patches attached to https://www.cups.org/str.php?L4258). This
// allows for automatic PPD generation already with CUPS versions older
// than CUPS 2.2.x. We have also an additional test and development
// platform for this code. Taken from cups/ppd-cache.c,
// cups/string-private.h, cups/string.c.
// 
// The advantage of PPD generation instead of working with System V
// interface scripts is that the print dialogs of the clients do not
// need to ask the printer for its options via IPP. So we have access
// to the options with the current PPD-based dialogs and can even share
// the automatically created print queues to other CUPS-based machines
// without problems.

char ppdgenerator_msg[1024];


//
// Human-readable strings in the PPDs generated by the PPD generator for
// using driverless IPP printers with CUPS
//
// To allow for translated/localized PPDs we use the standard set
// of human-readable strings from the PWG:
//
// https://ftp.pwg.org/pub/pwg/ipp/examples/ipp.pot
// https://ftp.pwg.org/pub/pwg/ipp/examples/ipp.strings
//
// Creating those with translated human-readable strings would allow us to
// easily produce PPDs in other languges.
//
// Translations are supposed to go here (but none are available yet):
//
// https://github.com/istopwg/ippregistry/tree/master/localizations
//
// These standard strings are also part of CUPS' translation files:
//
// https://github.com/OpenPrinting/cups/tree/master/locale
//
// Here translations take actually place as part of the translations
// of CUPS itself.
//
// We take the files from the CUPS installed into the system (as the PPD
// generator actually does not make sense without CUPS) but currently
// only use the English version. It is not complicated to check the user
// language in the printer's IPP response via the
// attributes-natural-language attribute and then request an appropriate
// language version of the files if available. The printer-specific
// strings are downloaded from the printer following the URI in the
// printer-strings-uri attribute and are in the selected language.
//
// It is not clear whether PPD translation will get fixed in the PPD
// generator as the need of PPDs in CUPS will go away with version
// 3.x.
