Pulojekiti ya OpenPrinting inapereka kutulutsidwa kwa makina osindikizira a CUPS 2.4.0 (Common Unix Printing System), omwe adapangidwa popanda kutenga nawo mbali Apple, yomwe kuyambira 2007 yakhala ikuwongolera chitukuko cha polojekitiyi, itatenga kampaniyo Easy Software Products, yomwe idapanga. MAKAPU. Chifukwa cha kuchepa kwa chidwi cha Apple posunga makina osindikizira komanso kufunikira kwa CUPS ku Linux ecosystem, okonda ochokera ku gulu la OpenPrinting adayambitsa foloko momwe ntchitoyo idapitilira popanda kusintha dzina. Michael R Sweet, mlembi woyambirira wa CUPS, yemwe adachoka ku Apple zaka ziwiri zapitazo, adalowa nawo ntchito pa foloko. Khodi ya pulojekitiyi ikupitilira kuperekedwa pansi pa layisensi ya Apache-2.0, koma malo osungiramo foloko ali ngati malo osungira, osati a Apple.
Madivelopa a OpenPrinting adalengeza kuti apitiliza chitukuko mosadalira Apple ndipo adalimbikitsa kuganizira foloko yawo ngati projekiti yayikulu Apple itatsimikizira kuti alibe chidwi pakupititsa patsogolo magwiridwe antchito a CUPS komanso cholinga chake chodziletsa kusunga codebase ya CUPS ya macOS, kuphatikiza kusamutsa. zokonza kuchokera ku foloko kuchokera ku OpenPrinting. Kuyambira koyambirira kwa 2020, chosungira cha CUPS chosungidwa ndi Apple chakhala chokhazikika, koma posachedwa Michael Sweet wayamba kusamutsa zosintha zomwe zidasokonekera, pomwe akutenga nawo gawo pakupanga CUPS munkhokwe ya OpenPrinting.
Zosintha zomwe zawonjezeredwa ku CUPS 2.4.0 zikuphatikiza kuyanjana ndi makasitomala a AirPrint ndi Mopria, kuwonjezeredwa kwa chithandizo cha kutsimikizika kwa OAuth 2.0/OpenID, kuwonjezera thandizo la pkg-config, chithandizo cha TLS ndi X.509, kukhazikitsidwa kwa "mapepala a ntchito- col" ndi "media-col", kuthandizira kutulutsa mu mtundu wa JSON mu ipptool, kusamutsa USB backend kuti igwire ntchito ndi ufulu wa mizu, ndikuwonjezera mutu wakuda pa intaneti.
Zimaphatikizanso zaka ziwiri zokonza zolakwika ndi zigamba zotumizidwa mu phukusi la Ubuntu, kuphatikiza kuwonjezera kwa zinthu zofunika kugawira stack yosindikizira yochokera ku CUPS, zosefera makapu, Ghostscript ndi Poppler mu phukusi lokhala ndi Snap (Ubuntu mapulani switch. ku chithunzithunzichi m'malo mwa phukusi lokhazikika). Makapu-config ndi kutsimikizika kwa Kerberos kwachotsedwa. Zokonda za FontPath, ListenBackLog, LPDConfigFile, KeepAliveTimeout, RIPCache, ndi SMBConfigFile zachotsedwa mu cupsd.conf ndi cups-files.conf.
Pakati pa mapulani otulutsa CUPS 3.0 ndi cholinga chosiya kuthandizira mawonekedwe osindikizira a PPD ndikusunthira ku kamangidwe ka makina osindikizira, opanda PPD komanso kutengera kugwiritsa ntchito chimango cha PAPPL popanga mapulogalamu osindikiza (CUPS Printer Applications. ) kutengera protocol ya IPP Everywhere. Akukonzekera kuyika zigawo monga malamulo (lp, lpr, lpstat, kuletsa), malaibulale (libcups), seva yosindikizira yapafupi (yoyang'anira zopempha zosindikizira zapafupi) ndi seva yosindikizira yogawana (yomwe ili ndi ntchito yosindikiza pa intaneti) kukhala magawo osiyana. .
Tikumbukire kuti bungwe la OpenPrinting lidapangidwa mu 2006 chifukwa chophatikiza pulojekiti ya Linuxprinting.org ndi gulu logwira ntchito la OpenPrinting kuchokera ku Free Software Group, lomwe lidachita nawo ntchito yomanga makina osindikizira a Linux ( Michael Sweet, wolemba CUPS, anali m'modzi mwa atsogoleri a gululi). Patatha chaka chimodzi, ntchitoyi idakhala pansi pa mapiko a Linux Foundation. Mu 2012, pulojekiti ya OpenPrinting, mogwirizana ndi Apple, idagwira ntchito yokonza zosefera makapu ndi zinthu zofunika kuti CUPS igwire ntchito pamakina ena kupatula macOS, kuyambira ndi kutulutsidwa kwa CUPS 1.6, Apple idasiya kuthandizira kusindikiza kwina. amagwiritsidwa ntchito ku Linux, koma alibe chidwi ndi macOS, komanso adalengeza kuti madalaivala amtundu wa PPD satha. Munthawi yake ku Apple, zosintha zambiri ku CUPS codebase zidapangidwa ndi Michael Sweet.
