Hello, I've recently start to work with Python.
I'm developing a managment software for a swimming pool, this software needs to print stuff directly from the website. I'm using Ajax request and shell exec to call a Python script which launch the print job. The script to print an image works fine with a standard printer but, I've to print on a card printer (FARGO-DTC1250e). When I launch a print job from the website, the python script launch the job on the printer, that's ok. The probleme is that I have a substantial quality deterioration .. The image printed on the card looks bad. I first thought it was because of the DPI which was incorrectly configurated but I've type : printer_dpi = hDC.GetDeviceCaps (LOGPIXELSX), hDC.GetDeviceCaps (LOGPIXELSY) And I get (300, 300) which is correct. I'm sure the problem is about the Python script, I've tried to start the print job directly from Windows, the image quality is perfect. I don't know anymore where to search, eventually when the script draw the image ? In this part of the code ? dib = ImageWin.Dib (bmp) scaled_width, scaled_height = [int (scale * i) for i in bmp.size] x1 = int ((printer_size[0] - scaled_width) / 2) y1 = int ((printer_size[1] - scaled_height) / 2) x2 = x1 + scaled_width y2 = y1 + scaled_height dib.draw (hDC.GetHandleOutput (), (x1, y1, x2, y2)) I hope you'll have the time to help me.
