There generally isn’t a common desktop printer that will directly print a 1-meter continuous image onto real 35mm photographic film. Older film recorders could transfer digital images to photographic media, but they were typically made for 35mm slides or other standard formats, not long continuous strips.

The most practical options mentioned are:

1. Use a prepress/high-contrast film service: Commercial prepress providers can expose digital artwork onto high-contrast film, sometimes in long custom lengths. This is probably the closest established process to what you want.
2. Use transparent media instead of photographic film: Inkjet-printable transparency film or clear continuous media may be easier to work with if true photographic film isn’t essential.
3. Build a custom transport/recording solution: If you specifically need 35mm film dimensions, sprocket compatibility, or a continuous strip, a custom setup may be more realistic than finding an off-the-shelf printer.

If your design requires sprocket holes and true 35mm handling, that makes standard printing options much less practical. In that case, a specialist film service or a custom-built system is likely the best route.
