QUESTION
Hello my favorite people!
I am trying to send an email after submitting a form, with the AUTO INCREMENT number attached to the email because the AUTO INCREMENT number is the clients Job Card Reference Number. So far i have successfully created the insert script which inserts the data into the database perfectly, and also sends the email too. But does not attach the AUTO INCREMENT number into the email. The INT(11) AUTO INCREMENT primary key is "job_number" in my MySQL database.
Here is my insert page:

}
if($insertId){
// do stuff with the insert id
}
QUESTION
I have downloaded the most recent UPD PCL6 driver from HP home page. Its version 7.0. We are using a solution call HP Access Control (16.8.1) which is a so called pull print solution. I created a queue on my Windows Server 2016 and created a port. The HP Access Control comes along with its own port monitor. I assigned the port to the queue and when I open the printer properties I get an error:
Function address 0x00007FFEB9E06402 caused a protection fault. (exception code 0xc0000005)
I have done this installation some time ago with the same version of HP Access Control and there all worked. Unfortunately I deleted that VM. But I believe I had an older version of UPD installed. Server operating system was also WS 2016.
...ANSWER
Answered 2021-Jun-15 at 09:42I had posted the same question in the HP forum and got an answer. For those who are interested:
**
The current UPD driver seems to have an issue if you assign it to ports like LPT1 or File or 3rd party port monitors like those from pull print solutions.
There seems to be a simple workaround:
If you can access a printer that is in your network, then you can create a direct TCP/IP port and assign it to the queue you are having problems with.
Then you can open properties or any other menu you get this error and then make the changes you would like to do.
You can then re-assign the queue to the port which caused the error.
Alternatively, if you still have an older UPD version and that still is fine for you then you can install the older version.
You should keep in mind though that the older version may not support brand new printer models from HP.
But if you have not the latest freshly released models you should be fine. **

In the following example, how would one utilize flex classes to make columns no.3 and 4 the same height as columns no.1 and 2? Without Javascript, that is.
More specifically, how would I make the height of all columns change automatically to the height of the column with the biggest content?

QUESTION
Right now I am developing web which has ability to connect thermal printer. I am using angular framework, and I successfully connect the thermal printer with USB using library ng-thermal-printer. But I want to my web also being able to connect thermal printer via web bluetooth which is BLE (Bluetooth Low Energy). As far as I know, BLE has specification in term of GATT and has services and characteristics in it.
The progress I did so far, I can connect and send a value to the thermal printer device in a Service and a Characteristic, let's say Service with UUID AS and Characteristics with UUID AC, using my android phone with the help of application named nRF Connect. Targeting Service AS and send hexadecimal value at charateristic AC make me successfully print something on the thermal paper.
But there is a problem. After knowing the right service and characteristic. I implemented it in my project. But, my chrome browser console showed error:
- Origin is not allowed to access any service... and it told me to add optionalServices when requestiDevice()
- After I added Service AS in property optionalServices, the console showed error DOMException: Connection failed for unknown reason. The errors showed both in chrome PC and chrome android.
NB:
- I have enabled Experimental Web Platform features on chrome
- I have enabled Use the new permissions backend for Web Bluetooth on chrome
- I have enabled Allow invalid certificates for resources loaded from localhost. on chrome
- I have enabled Enable new USB backend on chrome
- I have used https.
Additional question. is bluetooth connection that application nRF Connect used different from BLE? if so, why it displays services and characteristics?
...ANSWER
Answered 2021-Jun-14 at 07:34I'd recommend you try sending those hex values directly from the about:bluetooth-internals page and see if you can reproduce the connection error from there as well. See https://web.dev/bluetooth/#tips
If so, check out https://www.chromium.org/developers/how-tos/file-web-bluetooth-bugs to learn how to properly file a chromium bug so that the team can fix the underlying issue.
If not, could you share your JS code so that we can help you diagnose what could be going wrong in your code?

QUESTION
Im using a thermal printer (Hoin POS-58) to print receipts but i dont like the final result due to ugly font styles.
Im setting font-family and font-size in css print media query but as i told you the results are poor.
However, I can see how the selftest page font are much more pretty.
Do you know what font is "Font-A" or how can I set a propper font or configure printer to print the same way than in selftest page?
Im using Ubuntu 18.04 and google chrome.
...ANSWER
Answered 2021-Jun-05 at 12:18The thermal receipt printer can print beautifully at the lowest cost when requesting printing of text with character code.
In that case, the font data held by the printer is used, and it has only a few types of fonts with different character sizes (number of dots).
The font does not have a name like that given on a PC, etc., and is usually named Font-A/Font-B/Font-C.
However, there is no standard for font content and it depends on the vendor and model.
Also, unlike PC fonts, it is not possible to specify the size in 1-point units, and the decoration of characters can only be specified within a poor range.
On the other hand, the print result you got is probably that the application and the print driver have expanded the print content into a bit image and requested the printer to print it as a bit image.
The method of developing and printing on a bit image can produce poor results, such as yours, or you can obtain precise results, such as photographs.
It depends on how beautiful and precise the bit image can be created when creating print data.
There are two directions you can do.
One is to improve the beauty and fineness of the bit image data for printing to be created while keeping the current method.
The other is to stop creating print data as a bit image, to request printing by text in character code, and print contents and printer by the control code supported by the printer (usually ESC / POS original extension). Is to switch to control.
In this case, you will need to change everything from the printer's hardware mode settings to the printer driver to the application's control method.
