I just purchased an HP all in one printer and scanner but because I use Linux I can't scan directly to my desktop. As a result I'm having to scan to email and I just noticed that my picture file size was only 244 KB. That's seems small to me and I'm worried that the scanner lacks in the quality departement. I've already check the settings and there's no where to set or change the DPI of scans. Any input would be appreciated. Thanks.
