O projeto OpenPrinting apresentou o lan\u00e7amento do sistema de impress\u00e3o CUPS 2.4.0 (Common Unix Printing System), desenvolvido sem a participa\u00e7\u00e3o da Apple, que desde 2007 controlava totalmente o desenvolvimento do projeto, tendo adquirido a Easy Software Products, criadora do CUPS. Devido \u00e0 perda de interesse da Apple na manuten\u00e7\u00e3o do sistema de impress\u00e3o e \u00e0 import\u00e2ncia geral do CUPS para o ecossistema Linux, entusiastas da comunidade OpenPrinting fundaram um fork, no qual o trabalho no projeto continuou sem mudar o nome. Michael Sweet, o autor original do CUPS, que deixou a Apple h\u00e1 dois anos, tamb\u00e9m se juntou ao fork. O c\u00f3digo do projeto continua a ser fornecido sob a licen\u00e7a Apache-2.0, mas agora o reposit\u00f3rio do fork \u00e9 o principal, e n\u00e3o o da Apple. <\/p>\n

Os desenvolvedores do OpenPrinting anunciaram que continuar\u00e3o o desenvolvimento independentemente da Apple e recomendaram que sua ramifica\u00e7\u00e3o seja considerada o projeto principal, ap\u00f3s a confirma\u00e7\u00e3o da Apple de que n\u00e3o tem mais interesse em desenvolver a funcionalidade do CUPS e que pretende apenas manter a base de c\u00f3digo do CUPS para macOS, incluindo a transfer\u00eancia de corre\u00e7\u00f5es do fork do OpenPrinting. Desde o in\u00edcio de 2020, o reposit\u00f3rio do CUPS mantido pela Apple estava em profunda estagna\u00e7\u00e3o, mas recentemente Michael Sweet come\u00e7ou a transferir as mudan\u00e7as acumuladas para ele, participando ao mesmo tempo do desenvolvimento do CUPS no reposit\u00f3rio do OpenPrinting. <\/p>\n

Entre as mudan\u00e7as introduzidas na vers\u00e3o 2.4.0 do CUPS, destaca-se a compatibilidade com clientes AirPrint e Mopria, a adi\u00e7\u00e3o de suporte \u00e0 autentica\u00e7\u00e3o OAuth 2.0\/OpenID, a inclus\u00e3o do suporte ao pkg-config, melhorias no suporte a TLS e X.509, a implementa\u00e7\u00e3o dos atributos «job-sheets-col» e «media-col», suporte para sa\u00edda no formato JSON no ipptool, a transi\u00e7\u00e3o do backend USB para opera\u00e7\u00e3o com permiss\u00f5es de root e a adi\u00e7\u00e3o de um tema escuro na interface web. <\/p>\n

O pacote tamb\u00e9m inclui corre\u00e7\u00f5es de bugs e patches acumulados ao longo de dois anos, fornecidos em um pacote para Ubuntu, incluindo funcionalidades necess\u00e1rias para a distribui\u00e7\u00e3o do stack de impress\u00e3o baseado em CUPS, cups-filters, Ghostscript e Poppler em um pacote autossuficiente no formato Snap (o Ubuntu planeja transitar para este snap em vez de pacotes comuns). As ferramentas cups-config e autentica\u00e7\u00e3o via Kerberos foram declaradas obsoletas. A partir dos arquivos cupsd.conf e cups-files.conf, o suporte para as configura\u00e7\u00f5es FontPath, ListenBackLog, LPDConfigFile, KeepAliveTimeout, RIPCache e SMBConfigFile, anteriormente declaradas obsoletas, foi interrompido. <\/p>\n

Nos planos para o lan\u00e7amento do CUPS 3.0 est\u00e1 a inten\u00e7\u00e3o de descontinuar o suporte ao formato de descri\u00e7\u00e3o de impressoras PPD e migrar para uma arquitetura modular do sistema de impress\u00e3o, totalmente livre de PPD e baseada na utiliza\u00e7\u00e3o da estrutura PAPPL para o desenvolvimento de aplica\u00e7\u00f5es de impress\u00e3o (CUPS Printer Applications) na base do protocolo IPP Everywhere. Componentes como comandos (lp, lpr, lpstat, cancel) e bibliotecas (libcups) ser\u00e3o transferidos para m\u00f3dulos separados. servidor<\/a> O m\u00f3dulo de impress\u00e3o local (respons\u00e1vel pelo processamento de solicita\u00e7\u00f5es locais de impress\u00e3o) e o servidor de impress\u00e3o compartilhado (respons\u00e1vel pela impress\u00e3o em rede). <\/p>\n

Vale lembrar que a organiza\u00e7\u00e3o OpenPrinting foi criada em 2006 a partir da fus\u00e3o do projeto Linuxprinting.org e do grupo de trabalho OpenPrinting da Free Software Group, que se dedicava ao desenvolvimento da arquitetura do sistema de impress\u00e3o para Linux (Michael Sweet, autor do CUPS, foi um dos l\u00edderes desse grupo). Um ano depois, o projeto passou a integrar a Linux Foundation. Em 2012, por acordo com a Apple, o projeto OpenPrinting assumiu a manuten\u00e7\u00e3o do pacote cups-filters com componentes necess\u00e1rios para o funcionamento do CUPS em sistemas diferentes do macOS, j\u00e1 que a partir do lan\u00e7amento do CUPS 1.6 a Apple descontinuou o suporte a v\u00e1rios filtros de impress\u00e3o e backends usados no Linux, mas n\u00e3o relevantes para o macOS, al\u00e9m de declarar obsoletos os drivers no formato PPD. Durante seu tempo na Apple, a grande maioria das mudan\u00e7as na base de c\u00f3digo do CUPS foi feita pessoalmente por Michael Sweet.
