Need to stop wasting ink

[bigten333]

My friend is using his Samsung Note 9 to document people attending his classes. He places the student's driver's license on top of a paper with typed information. He then needs to print this image for his business. When he prints, however, the file the background is gray instead of white which wastes ink.

I cannot find a setting to save the file as only black and white. It defaults to filetype .jpg . I'd rather it be .doc. because I'm thinking it would not print as a color(?) Image. The printer settings are set to black and white yet I continue to get colored images with the gray background.

Can any one tell me how to take the picture and then print it without the background printing g as gray?

Thank you.

I would reconsider the entire tracking process. Taking a photo of people's driver's license is a huge privacy risk to the students.

Welcome to Android Central! I agree with Mooncatt -- taking pictures of a driver's license is somewhat fraught, and a student could legitimately refuse to have it photographed. Do the students have some kind of separate student ID?

If they have some other ID that doesn't include sensitive info, then your friend could use the Google Drive Scan function (which scans an image into PDF format) -- there's an option there after snapping the shot to modify the filter, one of them being Black & White.
