Notes: HPLIP software is not used in support of scanning on certain multifunction products (MFP's), some of which are listed below. These products which use HP Digital Sending Technology allow scanning directly to email addresses, network folders, or other networked devices. These MFP's do not support the SANE or TWAIN APIs, so HPLIP which provides SANE support is not needed for these devices.
