HP PhotoSmart 7400 4800 1200 www.hp.com us-ascii MLC,PCL,PML,DW-PCL,DESKJET,DYN 7450 HP Photosmart 7400 series A hplip HP's 7-ink printer using three cartridges at once, a standard color (CMY), a black (K), and a photo cartridge (probably cmk). Because the printer's hardware does all dithering internally when HP's HPLIP driver is used, 7-ink printing is fully functional under free operating systems. It has ports on the side for inserting SmartMedia, CompactFlash, IBM Microdrive, SD, or Sony Memory Stick digital "film" and has a color LCD panel which displays your photos (as a digital camera does) so that you can select pictures to print easily. This way one can use the device as a digital photo lab without PC. To get all functionality of this printer working under Linux, especially also the non-printing features, like scanning, printer status, maintenance, and photo download from memory cards, use the <a href="show_driver.cgi?driver=hplip">HPLIP driver package from HP</a>. It has a USB port on its front side to directly connect a digital camera (HP only). Border-less (full bleed) printing on paper sizes up to Oufuku-Hagaki is supported with the HPLIP driver. Best output quality reachable with the HPLIP driver (printer compatible to HP DeskJet 990C), especially the 1200-dpi high resolution mode gives excellent photo quality. When used with HP's HPLIP driver, this printer auto-detects the paper type and ink cartridge type and does appropriate dithering and colour adjustment internally, controlled by the hardware. So even when Ghostscript with the HPLIP driver only renders the image with 300 or 600 dpi, the higher resolutions are used for the internal dithering. So if you insert photo paper, the printer will print in photo quality, no paper type choice in the driver's options is needed. There is also a special high resolution mode where the image is rendered in 1200 dpi and interpolated to 4800x1200 dpi by the hardware, without paper detection, intended for photo paper only. This printer supports an optional duplex unit (probably supported by the HPLIP, "cdj970", and "pcl3" drivers). When the black and/or the photo cartridge is not installed the printer does not stop working, it switches automatically to a 6-, 4-, or even 3-ink process and goes on printing, but slower and in an appropriately lower quality.
