Epson XP-.332 inkjet štampač Print/scan/copy/wifi Veoma dobro očuvan Epson štampač u ekstra dobrom stanju. Nije mnogo ni odštampao tj radio uopšte . . . . dolazi sa novim kertridžima. Za ovaj model Epsona kertridzi postoje zamenski i kod nas i ima ih uvek i nisu uopšte skupi. .. cena je veoma povoljna. Odlično štampa na svaku vrstu papira . .. uostalom opštepoznata stvar za svakog Epsona. Veoma lako se instalira njegov upravljački softver na računar i nije velik a takdodje i sa lakoćom se povezuje na bežičnu wifi mrežu i radi besprekorno. Moguće ga povezati i sa mobitelom, tabletom. .. laptopom. .. štampati sa udaljene lokacije bez problema ikakvih kad se pravilno konfiguriže uredjaj. Štampač se može povezati putem wireless opcije koju ima štampač pa stoga usb kabal mu i ne treba nizašta. Ako nekome ipak treba usb kabal neka mi napomene da pošaljem sa štampačem inače uz ove štampače ne šaljem usb kablove jer su bespotrebni. Štampač je pregledan i testiran . . . . test stranice vidite na slikama. Sve je savršeno. Test stranice koje vidite dolaze sa štampačem inače . Uredjaj je kao nov i spreman za dalje korištenje. Imam trenutno još jedan ovakav Epson samo drugi model i on je takodje na oglasima. .. .Inače imam uvek veoma dobrih inkjet štampača sa povoljnim cenama. Svaki štampač koji mi stigne se servisira, pregleda i na kraju testira na sve funkcije tako da dobijate siguran i pouzdan štampač uvek od mene. Može lično preuzimanje naravno ali ako se šalje onda Postekspresom šaljem. . . najsigurnije. Poštarina vam je manja za 50% ako uplatite otkupni iznos na moj bankovni račun pre slanja jer onda mogu da šaljem bez otkupa kao paket a stiže istovremeno kao i kad ide kao postekspres. Ovo nije uslov nikakav ali tek onako pišem jer nekome znači i neki ljudi traže upravo tako da im se pošalje paket. Jer skupa je dostava previše za naš standard kao i sve ostalo.
