Hi @saravanacs What is the SUNMI device you are using? I can only verify on sunmi V1.

saravanacs commented 5 years ago

@tmalbonph Hi sir, i use Sunmi V1

@tmalbonph Hi sir, i use Sunmi V1

  1. For paper not available, you can only detect it while your printing.
  2. If you are not targeting Native java code, you won't be able to check the status of the printer unless you remember its status during printer setup.
  3. If you are targeting Javascript base solution like phonegap and ionic3+, I can help you but the code is not in the public domain.
  4. Refer to the updated source here: https://github.com/tmalbonph/cordova-plugin-sunmi-inner-printer

@tmalbonph I write below code for printing data, but before printing check printer is available and above mentioned validations

checkPrint(data) { /try { //this.printerInfo = sunmiInnerPrinter.hasPrinter(); sunmiInnerPrinter.printerInit(); sunmiInnerPrinter.printTextWithFont('\nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers \nABC Computers ', 'Calibri', 36); if (JSON.stringify(sunmiInnerPrinter) !== "{}") { this.printerInfo = JSON.stringify(sunmiInnerPrinter); return; } this.printerInfo = sunmiInnerPrinter.hasPrinter(); // it is safe to use sunmiInnerPrinter here } catch (err) { this.printerInfo = ("error: " + JSON.stringify(err.message)); }/ try {

var address = data.BranchAddress; //var name = "Saravana Kumar. M" var receiptNo = data.ReceiptNo; var subscriberName = data.SubscriberName; var receivedAmount = data.ReceivedAmount; var pendingAmount = data.PendingAmount; var advanceAmount = data.AdvanceAmount; var paymentMode = data.PaymentMode; var collectionAgent = data.PreparedBy; var group = data.Group; sunmiInnerPrinter.printString("Receipt No: "+receiptNo+ "\n"+"Date : "+'20-09-2019'); sunmiInnerPrinter.printTextWithFont('\n\t Test Pvt.Ltd ', 'Segoe UI Black', 32); sunmiInnerPrinter.printString("\n\t"+address+"\n"); sunmiInnerPrinter.printTextWithFont('\nName : '+subscriberName, 'Arial Black', 30); sunmiInnerPrinter.printString("\n------------------------------\n"+"Group : "+group+"\n"+"Received Amount : Rs. "+receivedAmount+"\n"+"Pending Amount : Rs. "+pendingAmount + "\n"+ "Advance Amount : Rs."+advanceAmount+"\n"+"Payment Mode : "+paymentMode+"\n"+"------------------------------"+"\n"+"* System generated Bill."+"\n"+"\t Prepared by : "+collectionAgent+"\n"+"No Signature Needed\n"+"\n\t\t\t\t\tThank You ..!!\n\n"+"\n\n") } catch (err) { this.printerInfo = ("error: " + JSON.stringify(err.message)); } }

You will need to use the plugin entry here: cordova-plugin-sunmi-inner-printer/www/innerprinter.js

tmalbonph commented 5 years ago

For example

  printString: function (text, resolve, reject) {
    exec(resolve, reject, "Printer", "printString", [text]);
  },

there is a resolve and reject parameter entry, at reject callback, you can detect status of the printer being printed in progress. That is the only reliable way to check for the status.

  printString: function (text, resolve, reject) {
    exec(resolve, reject, "Printer", "printString", [text]);
  },

Where i put this code sir. I posted my print function code above . Please edit that code sir and send me where set resolve and reject functionality

It is not that simple, You need to code at a minimum of 120-550 lines of code to make the robust printing code works on SUNMI V1 using Javascript. More codes if your using ionic3+

If you want to get your hands dirty; you need to digest my suggestion from top to bottom on this thread here: https://github.com/labibramadhan/cordova-sunmi-inner-printer/issues/14

Yes that is the basic idea, as I have mention on top of this thread, you need to provide both the resolve and reject callback to monitor status of your printer and the data your application is printing.
