Notes on Printing Images without Using the Printer Driver

Mass Storage mode supports JPEG image printing. The printer converts color JPEG files to black and white using the dithering process, which could result in fuzzy images. To improve image quality, avoid or turn off any functions that preprocess images.

Your printer supports an Object Push Profile (OPP) when printing via Bluetooth.

  • Only JPEG images can be printed, that is, this function is limited to files with the .jpg extension.
  • The maximum file size is 16 MB.
  • The maximum resolutions are as follows:
    • RJ-3235B/RJ-3255WB

      Height × Width = 24000 dots × 576 dots

    • RJ-4235B/RJ-4255WB

      Height x Width = 24000 dots × 832 dots

    If these limits are exceeded, the data received by the printer is discarded and not printed.

  • Print is at 1 pixel = 1 dot.
  • The printer performs binary processing (simple binary) to print the image.
  • The image is printed with the height-to-width proportions of the received data.
