The NP-1 print image data taken by a mobile phone with camera using infrared communication function, so you dont have to worry about connecting cables or plugging the recording media. The printer is easy to operate, just turn on the power and then select the image you want to print with your phone, and you can print it wirelessly using infrared communication. For printing, we use a film for the popular instant camera "CHEKI" which is popular in card size photographs, so you can easily buy it at many window openings such as convenience stores, camera shops, and appliances, so you wont miss an important print opportunity. In addition, the film is highly sensitive (ISO 800) type so it can form images with a slight amount of light, and it can print approximately 100 prints with a small primary battery (2 lithium batteries). In addition, the image data is written using a "line-sequential exposure method" that practically performs the three primary colors (R, G, and B), and it will be output in only 15 seconds (*2) after receiving the data. ★Printing method, Instant photography method, Film size , Print size , Fujifilm instant color film, instax mini (film), 86 mm x 54 mm, 62 mm x 46 mm, Print pixels: 480 x 640 dots, Print resolution, 10.0 dots/mm (254 dpi), print gradation, RGB color 256 scale, image writing time, film write film ~ To send out: about 1 5 seconds Film from emission to image appear: about 24 seconds (25 degrees Celsius) interface Infrared interface Printable Image data format JPEG Printable image data size up to 1664 x 1248 pixels up to 650 kbytes Other features Print and REPEAT button can be reprinted the last image Brightness Adjusted / (Lighten)= Brightness (Darken)= Brightness (Darken)= Brightness (Darken)= Brightness (Darken)= Brightness (Darken)= Brightness (Darken)= Brightness (Darken)= Brightness (Darken)= Dim film sends out Electric LCD Display Film Counter (remaining number display), Brightness Adjustment, Battery Capacity, ERROR Display, Power Supply, Lithium Battery, CR2 Printable Yield: Approximately 100 sheets (according to our test conditions), Auto Power Off Function, Power Consumption: 2.5 W (when printed), Other Film Pack Check Window, Size 4.7 x 1.8 x 45.0 mm (excluding protruding parts) Weight: 8.8 oz (250 g).
