There are a lot of complications involved in this.

First, as I answered the previous question, if you are using POS for.NET(including OPOS/JavaPOS), don't send the printer's ESC/POS control command directly with the PrintNormal method.

If you want to print a QR code, it may be supported by PrintBarcode method, please check the ADK document of EPSON, and if you can't find it in the ADK document, please contact EPSON support desk.

It is possible to send ESC/POS control commands for the printer according to the UnifiedPOS specification.
A UnifiedPOS POSPrinter escape sequence called "Path through embedded data" (ESC|[*]#E) will send the bytes of data specified in # directly to the printer.
However, it is assumed that the service object supports the feature. Please check with your ADK documentation or support contacts for support availability.

Next, it depends on whether you're using a POS for.NET native service object or an OPOS service object via COM Interop.

When using OPOS service objects, the conversion from Unicode to ANSI code pages is done automatically by the OLE runtime function during the method call, and character codes greater than 127 can be changed by the system code page. Also, if there is a 0x00 in the middle of the data, it will be terminated there and the rest of the data will be ignored.

This is because the parameter of the PrintNormal method are string, not a byte array.

ILegacyControlObject.BinaryConversion property of the service object can be changed to Nibble or Decimal instead of the default value of None.
However, depending on the implementation of COM Interop of POS for.NET, attention may be needed, so it is better to contact the support desk about how to use it.

If you're using a native service object in POS for.NET, it depends on how it's implemented. Again, please check with your ADK documentation or contact support desk for more information.

Try this- update previous state.

Empty strings evaluate as False in a boolean context. Use filter to get at just the columns that start with feature. Then use astype(bool) and followed by any(axis=1)

You can't call a function in your php file directly from the client. You can, however, pass data back which lets you determine which function to call.

For example, you could send back a query string test1.php?functionName=condCheckedUpd, and then in your test1.php file, you can check for it:

For 2D arrays this method will work: array_map('array_filter', $d);

For more nested levels you can use pointers or recursive functions:

I agree with comments saying that this should not take 30 days to run so the bottleneck should be somewhere else. Probably the biggest offender is the huge string that you are building, instead of just dumping each line to file at every iteration (^).

(^) The biggest offender is more likely to have been the continue statement in the inner loop, as that will always force the code to compare the current line with all the elements in the lookup file, rather than stop at the first match. Replacing that with a break should be the way to go.

Here what I would do and see how fast this performs:

Using BeautifulSoup bs4 and lxml parser library to scrap xml data.

Per default, ember-data expects data payloads from the backend to be in JSON:API format. As @Lux mentioned, your payload isn't JSON:API compliant, therefore the findAll returns an empty array.

You can either tell ember-data about your custom data format by customizing Serializers or you change your backend to send JSON:API compliant data.

There are a lot of libraries supporting JSON:API. You could for example use jsonapi-serializer in your current express server, to serialize your payloads for ember-data (There even is an express server example).
