Il codice del framework \u00e8 scritto in C ed \u00e8 distribuito sotto la licenza Apache 2.0 con un'eccezione che consente il collegamento a codice sotto licenze GPLv2 e LGPLv2.    <\/p>\n<p>Nella nuova versione:  <\/p>\n<ul>\n<li class=\"l\"> \u00c8 stata aggiunta la possibilit\u00e0 di configurazione via Wi-Fi.\n<li class=\"l\"> \u00c8 stata introdotta la supporto all'accesso alla stampante tramite il protocollo IPP-over-USB (IPP-USB).\n<li class=\"l\"> \u00c8 stata implementata la ricerca di driver adeguati per la stampante e l'aggiunta automatica di funzionalit\u00e0 avanzate.\n<li class=\"l\"> \u00c8 stata aggiunta la modalit\u00e0 PAPPL_SOPTIONS_NO_TLS per disattivare la crittografia TLS.\n<li class=\"l\"> Sono stati aggiunti pulsanti e comandi per sospendere e riprendere il funzionamento della stampante.\n<li class=\"l\"> \u00c8 stata aggiunta l'API papplSystemSetAuthCallback per supportare meccanismi di autenticazione alternativi.\n<li class=\"l\"> \u00c8 stata implementata un'opzione per abilitare la compressione.\n<li class=\"l\"> \u00c8 stato migliorato il controllo simultaneo di pi\u00f9 stampanti.\n<li class=\"l\"> \u00c8 stato aggiunto il supporto per le piattaforme Windows 10 e 11.  <\/ul>\n<p>Ricordiamo che il framework PAPPL \u00e8 stato originariamente sviluppato per supportare il sistema di stampa LPrint e i driver Gutenprint, ma pu\u00f2 essere utilizzato per implementare il supporto per qualsiasi stampante e driver nella stampa su sistemi desktop, server e embedded. Si prevede che PAPPL possa accelerare l'adozione della tecnologia IPP Everywhere al posto dei driver classici e semplificare il supporto per altri programmi basati su IPP, come AirPrint e Mopria.    <\/p>\n<p>PAPPL include un'implementazione integrata del protocollo IPP Everywhere, che fornisce strumenti per accedere alle stampanti localmente o in rete e gestire le richieste di stampa. IPP Everywhere funziona in modalit\u00e0 senza driver (\"driverless\") e, a differenza dei driver PPD, non richiede la creazione di file di configurazione statici. \u00c8 supportata l'interazione con le stampanti sia direttamente tramite connessione USB, sia tramite rete utilizzando i protocolli AppSocket e JetDirect. I dati possono essere inviati alla stampante nei formati JPEG, PNG, PWG Raster, Apple Raster e \"raw\".      <\/p>\n<p>PAPPL pu\u00f2 essere compilato per sistemi operativi compatibili POSIX, inclusi Linux, macOS, QNX e VxWorks. Tra le dipendenze spiccano Avahi (per il supporto di mDNS\/DNS-SD), CUPS, GNU TLS, JPEGLIB, LIBPNG, LIBPAM (per l'autenticazione) e ZLIB. Basato su PAPPL, il progetto OpenPrinting sta sviluppando un'applicazione universale chiamata PostScript Printer Application, capace di funzionare sia con stampanti moderne compatibili con IPP (che utilizza PAPPL) che con stampanti pi\u00f9 vecchie per le quali sono disponibili driver PPD (utilizzando i filtri cups-filters e libppd).<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=56359\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041c\u0430\u0439\u043a\u043b \u0421\u0432\u0438\u0442 (Michael R Sweet), \u0430\u0432\u0442\u043e\u0440 \u0441\u0438\u0441\u0442\u0435\u043c\u044b \u043f\u0435\u0447\u0430\u0442\u0438 CUPS, \u043f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u0438\u043b \u0432\u044b\u043f\u0443\u0441\u043a PAPPL 1.1, \u0444\u0440\u0435\u0439\u043c\u0432\u043e\u0440\u043a\u0430 \u0434\u043b\u044f \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u043a\u0438 \u043f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u0439 \u0434\u043b\u044f \u043f\u0435\u0447\u0430\u0442\u0438 \u043d\u0430 \u0431\u0430\u0437\u0435 \u043f\u0440\u043e\u0442\u043e\u043a\u043e\u043b\u0430 IPP Everywhere, \u043a\u043e\u0442\u043e\u0440\u044b\u0435 \u0440\u0435\u043a\u043e\u043c\u0435\u043d\u0434\u0443\u0435\u0442\u0441\u044f \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u044c \u0432\u043c\u0435\u0441\u0442\u043e \u0442\u0440\u0430\u0434\u0438\u0446\u0438\u043e\u043d\u043d\u044b\u0445 \u0434\u0440\u0430\u0439\u0432\u0435\u0440\u043e\u0432 \u0434\u043b\u044f \u043f\u0440\u0438\u043d\u0442\u0435\u0440\u043e\u0432. \u041a\u043e\u0434 \u0444\u0440\u0435\u0439\u043c\u0432\u043e\u0440\u043a\u0430 \u043d\u0430\u043f\u0438\u0441\u0430\u043d \u043d\u0430 \u044f\u0437\u044b\u043a\u0435 \u0421\u0438 \u0438 \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u044f\u0435\u0442\u0441\u044f \u043f\u043e\u0434 \u043b\u0438\u0446\u0435\u043d\u0437\u0438\u0435\u0439 Apache 2.0 \u0441 \u0438\u0441\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435\u043c, \u0440\u0430\u0437\u0440\u0435\u0448\u0430\u044e\u0449\u0438\u043c \u0441\u0432\u044f\u0437\u044b\u0432\u0430\u043d\u0438\u0435 \u0441 \u043a\u043e\u0434\u043e\u043c \u043f\u043e\u0434 \u043b\u0438\u0446\u0435\u043d\u0437\u0438\u044f\u043c\u0438 GPLv2 \u0438 LGPLv2.
