Ekuqaleni ulwimi olulungiselelwe ukuprinta amaxwebhu kwiiprinta zalaser, i-Postscript yatshintshwa ngokukhawuleza ukuze ivelise iifayile ezichanekileyo kwiifetetetters ezisetyenziswe ngabashicileli bezorhwebo.
I-Adobe PostScript (iNqanaba 1)
Ulwimi lokuqala, ulwimi olusisiseko lubizwa ngokuba ngu-Adobe PostScript. I-Level 1 yaxhaswa xa iNqanaba 2 laziswe. Ngeemilinganiselo zanamhlanje, iziphumo zaso ziyimpumelelo, kodwa nje ngeenguqulelo ezintsha ze-software ziqulethe izixhobo ezintsha ezingekho kwiinguqulelo zangaphambili, amanqanaba aPostScript alandelayo ancedisa inkxaso yezinto ezintsha.
I-Adobe PostScript Level 2
Ekhutshwe ngo-1991, iNqanaba le-PostScript lalingcono kakhulu kwaye lithembeke kunokuba lidlulileyo. Yongezelela inkxaso yobukhulu bekhasi ehlukeneyo, iifomati ezidibeneyo, ukuhlula ngokukhawuleza kunye nokushicilelwa kombala okungcono. Nangona kukho ukuphucula, kwakunzima ukuvunyelwa.
Adobe PostScript 3
I-Adobe isuswe "iNqanaba" elibizwa ngegama lePostScript 3, elakhishwa ngo-1997. Linikeza umgangatho ophezulu ophezulu kunye nokuphathwa kwegraphic engcono kuneenguqu ezidlulileyo. I-PostScript 3 isekela ubugcisa obubonakalayo, amafonti angaphezulu, kwaye isantya ukunyathelisa. Ngamazinga angaphezulu kwama-256 amakhreyithi ngombala ngamnye, i-PostScript 3 ibangela ukuba ibhendi ibe yinto edlulileyo. Ukusebenza kwe-intanethi kwaqaliswa kodwa ayiqhelekanga kusetyenziswa.
Kuthiwani NgePostScript 4?
Ngokutsho kwe-Adobe, akusayi kuba nePostScript 4. I- PDF yiplani yokushicilela isizukulwana esilandelayo ngoku ikhethwa ngabachwephesha kunye nabashicileli basekhaya. I-PDF ithathe iimpawu zePostScript 3 kwaye yandisa ngeendlela eziphuculweyo zendlela yokuphatha imibala, ukulungelelanisa i-algorithms yokuguqulela iphethini, kunye nokucwangcisa okufanayo, okunciphisa kakhulu ixesha elifunekayo ukucwangcisa ifayile.

Nangona kunjalo, ngoku ukuba i-PostScript 3 sele iphelelwe iminyaka engama-20, akunakwenzeka ukuba udibane nomshicileli okanye esinye isixhobo sokuvelisa esingahambelaniyo.
