Once upon a time, I used to scan things like this: scanimage > scan.pnm (I'd usually just pipe it into other commands, but something like that. Just like it says in the man page.)
Now the trouble is, the rest of my pipeline is failing because instead of printing a pnm file, scanimage is printing "Failed cupsGetDevices" followed by the scan output. pnm files are not supposed to start with the magic phrase "Failed cupsGetDevices", and so the pnm utilities are now refusing to operate on my scans. Why is this happening? How do I make it stop?
