Hi! What the model of printer do you use? When has the issue started? After last update or from the beginning of using printer? Additional details can be very helpful. Looking forward to hear from you

Hello i recently bought NETUM NT-1809DD bluetooth thermal printer from aliexpress.

It works but sometimes like 1 in 10 times it writes weird characters like in the picture below.I tried different settings and configuration it didnt worked in "other model" selection of loyverse printer settings.i tried Selecting model as epson tm-m30 it wrote but this time i think epson paper width is larger than 58mm so end of the letter and total price wasnt visable and no setting to adjust in loyverse on epson model.Are there any solution for this in the loyverse or we are only allowed to use loyverse recommended printers.

Based on the problem you described, the cause may be in one of 2 cases.

  1. First, the printer has a small buffer, and therefore when graphics are being printed, the buffer does not have time to process it and starts to choke.
  2. The second possible reason is that the printer may not support the esk / pse command flash buffer, which flushes the printer buffer before receiving a new piece of information.

Considering that your printer is bluetooth-enabled, which means that it has a slow exchange rate, I would recommend that you use text mode instead of graphic mode.

Thanks for your answer john. 
In the software they give to me there is a pos58 serial port settings and setting baud rate there which is shown on the screenshot.Default is 19200
Can i make it work with playing these settings?
