thermal-printer

问题 I am new in Android development. The following bloc is part of my APP's code, it does a simple job of select two columns of information from a local sqlite database's table, filter it by a scanned barcode and print the information retrieved plus the current date. My issue is the label feed control. Printer only execute Android APP's command when in ESC/POS mode, and doesn't stop the label paper in the right position for the next label to be printed. If anyone have ever made something similar

问题 My code is currently printing a barcode and hri text easily, but I want everything to be printed dead centre on the label. Can someone please tell me when I should declare the alignment command? I tried declaring it at the beginning and just before the barcode print command, but the barcode is still printing in the top left corner. Here is my align command: def align_esc(self,esc,n): ''' ESC|a|n 0<=n<=2,48<=n<=50 0,48 = Left; 1,49 = Mid; 2,50 = Right ''' align = [esc,n] align_prnt = bytearray

问题 I'm developing an aplication to manage multiples branches for a fast food locale, it's up in a shared hosting, and trying to use barryvdh/laravel-dompdf library to print in a thermal printer (client side) two tickets (one for invoice and other for order).

But right now the web print preview doesn't show, only register the invoice and log show this error 'PrinterController::pdf Invalid characters passed
