Ask why this is a "clearance" product. Usually clearance products are just a few oddments left over in store, not an amount sufficient to stock nearly all PCWorld stores and advertise on their web site. Is it because it didn't sell originally? If so, why didn't it?
Better off buying a standard Epson photo printer that takes up to A4 size paper. Most Epsons come with Photoquicker which gives many print options eg. 1, 2, 4, 8 or Index print (20, 40 or 80) on one A4.
Just purchased one from the local PCW, and it seems a nice little piece of kit for £29.97. Comes complete ready to work out the box, including sample photo paper, except the usb cable, which is £9.99 from PCW, but I buy mine for less than a pound each.
These units are made in China around 2004, and in the box there are a couple of special promotional offers like £10 off an HP bluetooth dongle, but it would appear the offer's may have finished in December 2004!.
Aldi have a Tevion professional photo printer, which was £79.99 now being offered at £49.99, for anyone in the market for a photo printer.
