Loop printing with bitmap

[RobertStuff]

Hi good day.. Have you tried printing loop with bitmap and text.

here is my code.. RNFetchBlob .config({ fileCache : true }) .fetch('GET', 'http://www.example.net:8000' + item[0])

       .then((resp) => {

           imagePath = resp.path()
           return resp.readFile('base64')
       })
       .then((base64Data) => {
            for(var i=0; i<data.netcode.length;i++){

            var note = data.netcode[i]
            Reactotron.log(note)

            SunmiInnerPrinter.printBitmap(base64Data, 200, 200)
            fs.unlink(imagePath)

            .then(()=>SunmiInnerPrinter.setAlignment(1))
            .then(()=>SunmiInnerPrinter.printString('\n'))
            .then(()=>SunmiInnerPrinter.setFontSize(26))
            .then(()=>SunmiInnerPrinter.printString(
                    note.service_category.company.company_name+ ' ' +  -  + ' ' +note.category.service.service+ ' ' + -  + ' ' +note.category.value+ ' ' + 'ID' + '\n'
            ))
            .then(()=>SunmiInnerPrinter.setAlignment(1))
            .then(()=>SunmiInnerPrinter.setFontSize(36))
            .then(()=>SunmiInnerPrinter.printString('Pin Code' + '\n' ))
            .then(()=>SunmiInnerPrinter.printString(note.code + '\n'))
            .then(()=>SunmiInnerPrinter.setAlignment(1))
            .then(()=>SunmiInnerPrinter.setFontSize(32))
            .then(()=>SunmiInnerPrinter.printString(note.service_category. + '\n'))
            .then(()=>SunmiInnerPrinter.setFontSize(28))
            .then(()=>SunmiInnerPrinter.printString(
                    note.service_category.message_service_en + '\n' +
                    note.service_category.message_service_kd + '\n' 
            ))
            .then(()=>SunmiInnerPrinter.setFontSize(26))
            .then(()=>SunmiInnerPrinter.printString(
                    'Serial Number' + '\n' 
            ))
            .then(()=>SunmiInnerPrinter.printString(note.serial_number + '\n'))
            .then(()=>SunmiInnerPrinter.setFontSize(24))
            .then(()=>SunmiInnerPrinter.printString(note.date_of_purchased + '\n'))
            .then(()=>SunmiInnerPrinter.setFontSize(28))
            .then(()=>SunmiInnerPrinter.printString('Code generated by eshortway'))
            .then(()=>SunmiInnerPrinter.printString('\n\n\n\n'))

but the result is like looping 1 item on the length of datasource.. The machice is printing the line base on the length

its like image image image same text same text same text and so on .......

Thanks.. cheers..

HI good day.. here's the sample images

I was trying to print this http://i.imgur.com/z77ijP6.jpg

but I achieve this http://i.imgur.com/ZoV1WOS.jpg

Thanks.. cheers..

[januslo]

Because you not wait for the print operation finish in your loop. Try with asycn- await operators instead

plz check this https://stackoverflow.com/questions/37576685/using-async-await-with-a-foreach-loop

[RobertStuff]

Thanks will try that...

Here.

return RNFetchBlob .config({ fileCache : true }) .fetch('GET', 'http://example.website.info:8000' + item[0])

           .then((resp) => {

               imagePath = resp.path()
               return resp.readFile('base64')
           })
           .then((base64Data) => {
                data.netcode.map(async (note) => {
                    Reactotron.log('start loop')
                const testing = await SunmiInnerPrinter.printBitmap(base64Data, 200, 200)
                    .then(()=>SunmiInnerPrinter.setAlignment(1))

                    ))
                    .then(()=>SunmiInnerPrinter.setAlignment(1))

                    .then(()=>SunmiInnerPrinter.setFontSize(28))
                    .then(()=>SunmiInnerPrinter.printString(
                            note.service_category.message_service_en + '\n' +
                            note.service_category.message_service_kd + '\n' 
                    ))
                    .then(()=>SunmiInnerPrinter.setFontSize(26))
                    .then(()=>SunmiInnerPrinter.printString(
                            'Serial Number' + '\n' 
                    ))
                    .then(()=>SunmiInnerPrinter.printString(note.serial_number + '\n'))
                    .then(()=>SunmiInnerPrinter.setFontSize(24))
                    .then(()=>SunmiInnerPrinter.printString(note.date_of_purchased + '\n'))
                    .then(()=>SunmiInnerPrinter.setFontSize(28))
                    .then(()=>SunmiInnerPrinter.printString('Code generated by eshortway'))
                    .then(()=>SunmiInnerPrinter.printString('\n\n\n\n'))
                    Reactotron.log('End of loop')
                    return fs.unlink(imagePath)
                })
                dispatch(setPrintPinCode({printCodeState: 'Code has been successfully printed.'})); 
           })

But when I remove the async/await the logs looks good but It also doesn't print correctly.

May show thing like this:

const Reactotron = {};
const RNFetchBlob={};
const SunmiInnerPrinter = {
    printBitmap(){
        return new Promise();
    }
};

export default class Test {

[RobertStuff]

Thanks with your prompt reply. I'll check it out thanks...

[RobertStuff]

Hi Im having an error in this part 'async print = (base64Data)=> {'

[RobertStuff]

Hi I have added another async function inside and it work perfectly... Thank you very much...

[januslo]

@RobertStuff cool man. so let's close this case.
