Printer chal raha tha, ab Offline kyun dikha raha hai?

Kal sab theek tha, aaj Offline, aur kuch badla bhi nahi. 10 mein se 9 baar router ne printer ko naya address de diya hai (bijli gayi, router restart hua, ya lease khatam) aur EasyKOT Desktop App purane address pe knock kar raha hai. Desktop App pehle printer ko uske hardware address se dhoondhta hai, isliye aksar aapke pahunchne se pehle yeh khud theek ho jaata hai.

Printer chale ya na chale, sale save ho chuki hai. Desktop App bill pehle apne andar save karta hai, print uske baad. Har symptom ki poori table mein baaki saare cases hain.

Sabse common wajah

Address badla hai. Printer wahin ka wahin hai.

Router ne printer ko naya address de diya. Router har address ek fixed time ke liye deta hai. Power cut ke baad network ka har device ek saath dobara maangta hai, aur kaun pehle wapas aaya us hisaab se address bant jaate hain. Toh jo printer .50 pe tha, woh .63 pe aa sakta hai.
Printer ka purana address kisi aur ne le liya. Naye phone ya smart TV ko printer ka purana IP mil gaya, toh knock ka jawaab wahi dega. Tab row pe Offline ke saath alag hint aata hai: us address pe koi jawaab de raha hai, par woh printer nahi hai.
Printer so gaya, ya cable nikal gayi. Wi-Fi printer khaali baithe apna Wi-Fi band kar dete hain aur pehla knock miss kar dete hain. Isiliye ek miss pe row Offline nahi hoti, lagaatar 2 miss chahiye. Phir bhi Offline rahe toh printer pe jaake power aur network cable check karo.

Fix

Pehle yeh karo.

Thoda ruko, Desktop App pehle se dhoondh raha hai

Ek baar accha connection ho jaaye toh Desktop App printer ka hardware address yaad rakhta hai, sirf IP nahi. Row Offline hote hi woh network se poochta hai ki yeh hardware address kahan gaya, naya address save karta hai aur agle check pe phir try karta hai. Raat mein DHCP ne address idhar-udhar kar diye, toh Desktop App kholne tak aksar pata bhi nahi chalta: row Offline hoti hai aur khud wapas aa jaati hai.

Phir bhi Offline hai toh Detect printers chalao

Settings → Printers & KDS → Detect printers rescan karta hai aur batata jaata hai ki abhi kaunsa round chal raha hai: pehle is computer ke USB aur Bluetooth port, phir printers ke factory address, phir network pe broadcast ki kaunse printers hain, phir Wi-Fi pe port 9100 wali har cheez ka sweep. Jo milta jaata hai, dikhta jaata hai. Agar aapka printer saved address se alag address pe mila, toh poori problem yahi thi.

Printer pe hi address check karo

Printer ka feed button dabake rakho aur switch on karo. Status slip niklegi, uspe IP address aur MAC dono honge. IP ke pehle teen number Desktop App ke IP se match hone chahiye: 192.168.1.x se 192.168.1.y theek hai, 192.168.1.x se 192.168.29.y nahi.

Address reserve karo taaki kabhi na badle

Router ke admin page mein DHCP reservation dhoondho (kabhi iska naam Address Reservation ya Static Lease hota hai), aur printer ka MAC uske abhi wale address se jod do. Ek baar, 2 minute, aur har power cut ke baad bhi printer ka address wahi rahega.

Rescan ke baad Detect printers screen: upar Epson ke liye router mein plug karne wali tip, neeche 'Detected printers — No printers found. Make sure the printer is on and on the same network (Bluetooth printers must be paired in OS settings first), then rescan — or add one manually,' aur Rescan aur Add manually buttons.

Detect printers ne rescan kiya aur kuch nahi mila: address badal gaya hai, ab printer ki apni status slip dekho.

Desktop App par

Printer ki row kya bolti hai.

Settings → Printers & KDS mein har printer ki apni row hoti hai. Us row pe status green dot se nahi, seedhe words mein likha aata hai. Is problem ke exact words yeh hain.

Jab tak problem hai: “Offline”, saath mein line “Can't reach the printer. Check power and the network cable.” Agar us address pe koi aur jawaab de raha hai, toh hint badal ke “Something answers at that address, but not a printer. Check the address.” ho jaata hai. Row ke neeche ek “How to fix this” khulta hai, jismein wahi fix hai jo is page pe hai.
Fix hone ke baad: “Connected”. Pichhle 5 minute mein fire hue tickets line se print ho jaate hain; usse purana ticket pehle hi ruk chuka hota hai, uske row pe Print dabao.

Ek miss hua knock Offline nahi hai. Wi-Fi printer apna Wi-Fi sulaata hai aur pehla check aksar miss karta hai, isliye row lagaatar 2 miss ke baad hi badalti hai. Jo printer bas der se jaagta hai, uske liye kabhi jhootha alarm nahi bajta.

Printer wapas aaye toh purane tickets khud print nahi hote. Review se chuno; sale chalti rehti hai.

Kuch lost nahi hota

Jo ticket chhoot gaya, woh kaise nikle.

Tickets queue hote hain, gayab nahi hote. Printer Offline tha tab jo bhi fire hua, woh Settings → Printers & KDS ke print queue mein baitha hai aur khud retry kar raha hai: 1 second, phir 2, 5, 15, 30 aur 60, uske baad har minute — 5 minute tak.
5 minute ke baad woh aapko bulata hai. Row pe “Not printed — waiting for your choice” aata hai aur tab tak dikhta hai jab tak aap kuch karte nahi. Print, Send to <another printer> ya Discard, sab usi row pe ek tap mein.
Fail hote hi aapko 4 options milte hain. Settle ya fire karte waqt printer na mile, toh Desktop App Retry now, Fix printer, Send to <another printer> aur Skip — keep it for reprint deta hai. Tab tak sale save ho chuki hoti hai. Yeh saare buttons sirf paper ke liye hain.

Ek dialog jiska title 'Counter Printer isn't connected — The order is saved. Counter Printer: Offline. What do you want to do?' hai, buttons Retry now, Fix printer aur Skip — keep it for reprint, peeche catalog screen pe laal '2 tickets need you' bar.

Settle ya fire karte waqt printer na mile, tab yeh options aate hain. Yeh dialog aane tak sale save ho chuki hoti hai.

Seedhe jawaab

Printer Offline dikha raha hai: log aur kya poochte hain

Static IP kahan set karu, printer pe ya router pe?

Router pe. Router ke DHCP reservation page pe printer ka MAC address daal do, usse hamesha wahi IP milega. Printer ki setting chhedne ki zaroorat nahi, aur printer kabhi reset hua toh bhi setting nahi jaayegi. MAC printer ki status slip pe hota hai: feed button dabake printer on karo. Printer ke andar static IP set karna bhi chalta hai, lekin tab woh IP router ki DHCP range se bahar honi chahiye, warna kisi din wahi address kisi aur device ko mil jaayega.

Power cut ke baad printer ne kaam kyun band kar diya?

Kyunki router restart hua aur usne address dobara baante. Printer theek hai, Desktop App bhi theek hai: Desktop App bas us address pe call kar raha hai jo ab printer ka nahi hai. EasyKOT printer ka hardware address dekh ke usse khud dobara dhoondh leta hai. Router pe DHCP reservation kar do, toh yeh hoga hi nahi.

Kya printer dobara add karna padega?

Nahi, aur karna bhi mat. Delete karke dobara add karne se settings chali jaati hain, aur woh saved hardware address bhi jisse automatic dhoondhna kaam karta hai. Detect printers chalao, ya existing row pe address edit karo, sab kuch bacha rahega.

Offline dikha raha hai, par printer ki light jal rahi hai.

Light jalne se yeh pata nahi chalta ki Desktop App printer tak pahunch pa raha hai ya nahi. Offline ka matlab hai us address pe lagaatar 2 knock ka jawaab nahi aaya. Printer pakka on hai aur pakka aapke Wi-Fi pe hai, toh agla shak do cheezon pe: router devices ko alag rakh raha hai, ya Desktop App doosre network pe hai. Dono ka apna page hai.
