If the digital camera uses a Type I CompactFlash (CF) card, the card can be inserted into the printer to print photos. The camera must support Digital Print Order Format (DPOF) version 1 or 1.1 to print directly from the CF card to the printer. Review the digital camera’s documentation to see if it supports DPOF files.
Photos can also be downloaded from the CF card onto the computer’s hard disk, and they can be printed from a software application such as HP Photo Printing Software. To print photographs on photo paper, see document BPD50466 - Paper Handling, Media Specifications, and Supported Media Sizes.
note:Only Type I CompactFlash cards are compatible with the HP Deskjet 450 printer. The printer cannot accommodate any form of Type II CF card, even though some User's Guides, Datasheets, etc. claim that Type II CF cards are supported.
