HP is planning to introduce two professional-level printers -- the Photosmart 8750 and the Designjet 90 series -- at next week's Photo Marketing Association (PMA) trade show in the US.

The Photosmart 8750 can produce pictures as large as 13-x-19 inches in approximately three-and-a-half minutes and print 4-x-6-inch shots in as little as 29 seconds.

Its nine-ink system uses HP's new Blue Photo inkjet cartridge, which enhances the blue shades in all output. HP will ship the printer in April with a $499 (around £275) price tag.

The 8750 features USB 2.0 and Ethernet ports, with 802.11b/g or Bluetooth wireless connectivity available through optional adapters, PictBridge technology for direct printing from compatible cameras and slots that accommodate CompactFlash Type I and II, Secure Digital, MultiMedia Card, Memory Stick, xD-Picture Card and USB flash drive.

The Designjet 90 series, which will arrive this summer, can accommodate paper up to 18-x-24 inches, with optional roll-feed capability for printing images up to 18 inches wide and 100 feet long.

Its six-colour ink system can produce images up to 2400dpi in resolution. Connectivity options include a USB port and a Centronics standard Open EIO for adding the printer to a network -- wireless capability can be added with an HP Jetdirect module.

The standard Designjet 90 will sell for $995 (around £550) while the 90r, which includes the roll-feed capability, will sell for $1,150 (around £633).
