HP has announced the DeskJet 990C, the PhotoSmart 1215 and the PhotoSmart 1218. Both PhotoSmart printers include CompactFlash and SmartMedia card slots, so photos from a digital camera can be printed directly without having to put them into a computer. The slots can also be used from uploading to a Mac or Windows PC. The three printers include HP’s new optical paper-sensing technology, which detects the type of paper in the printer’s paper tray using an optical sensor and adjusts the print settings accordingly. This can be turned off if necessary. The sensor can detect plain, glossy, photo and coated paper – and transparency paper – from most manufacturers. All of the printers have a maximum resolution of 2,400-x-1200dpi. The DeskJet 990C offers up to 17ppm in black-&-white and up to 12ppm in colour, as does the PhotoSmart 1218. The 1215 offers up to 15ppm and 12ppm. The DeskJet 990C also offers a 150-sheet paper tray, while the PhotoSmarts have a 4-x-6 photo paper tray. IBM has announced its first laser printer that is compatible with the Mac. The Infoprint 12 is 1,200dpi compact laser with a maximum print speed of 12ppm. It also works with Windows PCs. The Infoprint 12 has a 250-sheet paper tray with a 100-sheet auxiliary tray. A 550-sheet tray is also available as an option. It has 4MB of on-board memory, which is expandable up to 68MB. Options include PostScript 3 support and Fast Ethernet networking.
