FAQs & Troubleshooting

What is the JPEG printing and how can I use it?

Image data (JPEG) can be printed without using the printer driver.

JPEG images can be printed using the mass storage feature.
The Object Push Profile (OPP) is used for printing via a Bluetooth^® connection.
This printer will convert a color JPEG image to a ‘Black & White’ image using a dithering process.
When sending a JPEG image that is already ‘Black & White', this dithering process may make your printed image fuzzy.
To improve the image quality, try to turn off any preprocessing of the JPEG image.

Only JPEG images can be printed. (Limited to files with the .jpg extension.)
The maximum file size is 15.8 MB.
The maximum resolution is as follows:
Height × Width = 24000 × 832 dots
If these limits are exceeded, the data received by the printer will be discarded and not printed.
Print is at 1 pixel = 1 dot.
This printer performs binary processing (simple binary) to print the image.
The image is printed with the height-to-width proportion of the received data.
