Hello Zubair, Sorry for opening this old thread. But I have also encountered with the similar problem and really need a guidance. I am plotting two graphs using pyqtgraph, and then want to export the image and do print (using thermal printer to do it). It does not matter for me whether it will do printings directly when data arrives or after all data will be arrived. I am just keen on whether you had got a clear graph prints. Was you able to print smooth data (clear graph)? How had you acquired this?
