printerservice | Simple implementation standart android print API for custom | Android library

I'm trying to print a jasper report but it keeps giving me a FileNotFoundException error.

A little bit of context, the person who designed this, had the jrxml file outside the repository, using this code (and it works, it actually prints it)

I tried to use the AcceptHeaderLocaleResolver in my application. I have made a lot of searches, but I still don't understand how to use it correctly. For the moment, the following code is the one that's working:

HeaderLocaleResolver class:

I have been looking for a solution to print from web on client side this (https://medium.com/@yehandjoe/angular-2-raw-printing-service-56614d358754) is what i have been following it suggests to use qz tray to get access for printer. I have copied the code as it is but its not working.

whenever the function getprinters() is executed it says "qz is not defined"

i have imported packages using these npm commands

npm install qz-tray sha ws

npm install rsvp, this is my printer service code :

I've been stuck with the problem for almost a week now. The issue that I am facing is that when I set the application in debug mode, the printer functions work well; they return the correct responses and the sample texts are printed from the thermal printer the POS has.

However, when I switch the app to release mode, things start to behave a little differently. To give you a picture of what is happening, here is the correct method calls and responses. You can see that the request that goes to the OS is correct and the return values are correct too.

So I'm trying to get a response from a Promise in a Provider but I'm not having much luck.

My component never receives a response,

Today I updated my project from Spring Boot 1.5.9 to 2.1.1, and some of my tests stopped working. When i start the tests, error pops on console:

Field authEntryPoint in com.example.rest.config.SecurityConfig required a bean of type 'com.example.rest.service.auth.entrypoints.AuthenticationEntryPoint' that could not be found.

The problem is I have bean of this type defined in my SecurityConfig class, but I am overriding this configuration in my test package in TestApplication class. Security config is defined there as static inner class. I have tried different approaches including Spring profiles and @Primary annotation, but nothing seems to work and Spring doesn't pick my test configuration like it did before. Only thing that worked was when I deleted the non-test version of SecurityConfig class and test version became only bean of this type.

Can someone tell me how do I override this original configuration or how to turn off Spring Security just for testing? Or maybe there is a way to force Spring not to pick up that non-test @Configuration bean?

SecurityConfig.class

I am calling a custom Web API from my Angular app, and I need to JSON.parse() my response twice in order to access the properties. I am not sure why this is happening.

Am trying to format a receipt to a thermal printer. The printer can only align to one side at a time. using ESC/POS commands to reset and print to another alignment makes it print slowly and also loses the previous line it was supposed to print. Is there a way i can format the receipt before sending it to the printer? I would really appreciate any help.

This is my code:

I'm writing a PrinterService to control a proprietary printer and I try to use PDFRenderer to convert the PDF file sent by the PrinterManager to a bitmap to be sent to the printer.

I started from this example to use PDFRenderer.

I'm sure about the PDF file I receive but mCurrentPage.render(bitmap, null, null, PdfRenderer.Page.RENDER_MODE_FOR_PRINT); desesperately fill up an empty bitmap.

So I was wondering if PDFRenderer could need some context not available in a service.
