I have the same problem printing a pdf417 code as an image and with QR codes. I discard that it is my printer, since printing an image from windows via usb does it fast.

We had the same issue printing images. We fixed the issue adjusting the chunkSizeBytes argument when calling the printTicket function. The default value is 20. We change it to 256 and that was it, it worked perfectly.
