[chauvoluuhuong]

Hello guys,

I am developing application that control the label printer to auto print label from data input.

My solution i'am choosing is use CUPS. For more detail,

firstly i write python program that will generate image file from data input (image contain QR code, product seri number...)
second, i use CUPS command to print label from that image.

i followed CUPS document and test many case for using CUPS command. but still get failed.

please share me some of experience !

Thanks all
