Also included is an IrDA port for direct printing. This kind of print connection has the potential to be very useful, particularly with the increasing number of digital cameras and PDAs using infrared. There's a parallel and USB connector for regular printing. Print quality in draft mode is acceptable but really improves in normal or high definition mode. While it's possible to print at 2,400 by 1,200dpi, this has to be done on dedicated photo paper.
Normal paper can only take so much ink without becoming saturated.
To minimise human error, the print driver software restricts printing at the highest resolutions on unsuitable media. The DeskJet 990Cxi is the highest specified printer in the 900 series, which is reflected by its price. The innovative automatic optical paper sensor is useful and will no doubt become more proficient in future releases.
