            EOS thermal printer does not print Arabic characters properly when using Flutter framework
            Asked 2022-Mar-23 at 00:02

            Context:

            I have an EOS thermal printer, but it does not print Arabic characters properly like in this image below:

            As you can see, the Arabic text is printed incorrectly and from Left-to-Right (LTR), (it should be Right-to-Left - RTL).

            Note: You can clearly see the English text is printed perfectly at the end of the page.

            Question:

            How can I print Arabic text the right way in flutter?

            Additional Info:

            Flutter version: 2.5.3 (Stable)

            first I have used the esc_pos package and it didn't work. In the end, I've used the printing package to print an Arabic invoice and it works fine, and the explanation below

            This is the full code to use the printing package. first, create a class to pass the parameters to it(the parameters that you need to print) in my case 4 required param.

            Access printer connected at Virtual Printer Port (USB001) using python-escpos on Windows 10
            Asked 2022-Jan-11 at 10:00

            I have created a printing module, which work with printer connected at serial port using printer.Serial("COM5") interface provided by python-escpos.

            But now, I have to switch to USB printer rather than serial. My USB printer is connected at virtual printer port (USB001). Now, printer.USB() requires vendorID and productID but in my case when I see Device Instance Path, it does't contain vendorID and productID (screenshot is attached below). I am stuck here that how can I connect with this USB printer.

            Please note that my printer is R290 thermal printer and I have downloaded its driver from http://itambition.com/printer.html. The printer is connected at USB001 and test page is being printed successfully.

            I have resolved the issue using following steps:

            • connect USB printer
            • install R290 driver from http://itambition.com/printer.html. it will setup USB001 for usb printer
            • from printer & scanners menu, select printer properties and share the printer
            • open cmd as administrator and run:

            net use lpt1 \your-systems-hostname\printer-sharename

            • now connect printer.File("LPT1") interface of python-escpos and start printing

            I have two Bluetooth thermal printers as well as an integrated device.

            One of the printers doesn't support QR codes via GS ( k .. 49, so I'm printing by loading a file.bmp into a Bitmap kotlin class and then sending as image via GS v 0.

            The problem I'm facing is that when I print the QR image the other printer stalls mid-image.

            I must restart the printer for it to work properly, otherwise it'll print garbage.

            The source file has the following characteristics:

            • 82x82 pixels
            • 2.9x2.9 cm print size (needs to be 3 cm)
