Restaurant billing ke liye kaunsa thermal printer le?

ESC/POS zaroori hai, lekin bas wahi kaafi nahi. Connection, paper size, cutter aur aapke device se nikla real test print bhi check kare. 58 mm aur 80 mm dono bill print kar sakte hain.

ESC/POS

ESC/POS ke saath connection aur paper size bhi check kare.

ESC/POS woh command language hai jisme billing software thermal printer ko text, feed aur cut ke instructions bhejta hai. Listing ya manual mein ESC/POS ya "Epson compatible" pehla check hai.

Printer ka USB, LAN, Wi-Fi ya Bluetooth connection aapke laptop ya phone se match hona chahiye. Paper width sahi select honi chahiye, cutter kaam karna chahiye aur usi device se real test print nikalna chahiye. Ek model ka naam har firmware aur cable ki guarantee nahi hai.

Paper size

58 mm aur 80 mm dono bill print karte hain.

58 mm80 mm
Line width32 characters42, ya "80mm wide" setting par 48
ReadabilityLong names jaldi wrap hote hainNames aur amount ke liye zyada jagah
CutterTear bar common; cutter model par dependAuto-cutter zyada common
RollCompact, aam taur par sastaLamba chalta hai, jagah aur cost zyada

58 mm sirf KOT aur 80 mm sirf bill ke liye nahi hai. Dono dono kaam kar sakte hain. Busy counter par readable bill aur auto-cutter useful hote hain; chhote phone counter par compact printer useful ho sakta hai. Loaded roll aur EasyKOT Desktop App ki width setting same rakhe.

Connection

Jis device se print karna hai, uske hisaab se connection chune.

  • LAN / Wi-Fi. Counter aur kitchen ke network printer ke liye. Device aur printer same local network par hone chahiye; router mein printer ka address reserve karna accha hai.
  • USB. Ek Windows ya Mac Desktop App ke liye seedha option. Phone USB printer ko drive nahi karta. Data cable chahiye; charge-only cable kaam nahi karegi.
  • Bluetooth. Android phone ke liye. Printer pehle phone settings mein pair kare. Generic Bluetooth printer iPhone ka supported path nahi hai; iOS build Wi-Fi use karta hai.
  • Serial (RS-232). Purane desktop printers mein milta hai. Baud rate aur cable match karni padti hai; naya printer le rahe hain toh zaroorat confirm kare.
Checklist

Payment se pehle yeh 5 cheezein dekhe.

  • Listing ya manual mein ESC/POS.
  • 58 mm ya 80 mm, aur usi width ke rolls.
  • Aapke device ke liye sahi connection.
  • Busy bill counter ke liye auto-cutter.
  • Drawer use karte hain toh cash-drawer port; model manual se port aur voltage confirm kare.

Final check

Test page ke baad sample bill bhi print kare.

Printer ko connection guide se add kare, paper width chune aur Print test page dabaye. Ruler sahi aaye toh sample bill nikale. Dish names, quantity, amount, GST lines aur cut check kare.

EasyKOT ke print bytes se virtual 80 mm ESC/POS printer par nikla sample GST bill, jisme bill number, table, items, CGST, SGST aur paid total hai

Yeh Desktop App ke print bytes se nikla real 80 mm layout hai. Paper par Rs. aata hai, kyunki thermal-printer character sets mein ₹ glyph reliable nahi hai.

Baad mein blank, garbage ya offline status aaye toh printer troubleshooting guide dekhe. Failed ticket 5 minute ke baad queue se gayab nahi hota; wahan se retry ya doosra printer chune.

Printer ke sawaal

Straight answers.

Kaunsa printer EasyKOT ke saath chalega?
Aisa thermal printer dekhe jo ESC/POS support karta ho aur aapke device ke connection se match karta ho. Model aur firmware ka behaviour alag ho sakta hai, isliye koi certified brand list nahi hai. Printer add karke test page aur sample bill print kare. Dono sahi nikle, tabhi compatibility maan kar chale.
58 mm ya 80 mm: kya farak hai?
Dono bill aur KOT print kar sakte hain. 58 mm printer compact hota hai aur rolls aam taur par saste hote hain, lekin long dish names jaldi wrap hote hain. 80 mm bill padhna aasaan hota hai, roll lamba chalta hai aur auto-cutter zyada common hai. Desktop App mein wahi width chune jo printer mein lagi hai.
Bluetooth printer phone se chalega?
Android par paired Bluetooth printer ya Wi-Fi printer use kiya ja sakta hai. Public iPhone app abhi App Store mein nahi hai, aur generic Bluetooth thermal printer iPhone ka supported path nahi hai; iOS build Wi-Fi printer use karta hai. Apne phone se test print zaroor kare.
USB printer laptop ke bina chalega?
Nahi. Phone USB receipt printer ko drive nahi karta. USB ke liye Windows ya Mac par Desktop App chalaye. Phone se print karna hai toh Bluetooth ya Wi-Fi/LAN printer chune.
Thermal printer ko ink chahiye?
Nahi. Thermal paper heat se dark hota hai, isliye ink, ribbon ya cartridge nahi lagta. Sahi width ke rolls le, ek spare counter par rakhe aur rolls ko dhoop aur heat se door rakhe.
Printer service ke beech ruk jaaye toh kya kare?
Power, paper, cover, cable aur Wi-Fi ya Bluetooth connection check kare. Definitely failed ticket 5 minute tak retry hota hai; phir queue mein Print ya doosra printer chune. Result clear nahi ho toh app blind auto-retry nahi karta, kyunki duplicate bill nikal sakta hai.
