Lexmark is no longer really in the race when it comes to speed and quality. Their new warhorses are price and multi-functionality. This year, they will probably win on price ratio between function and product.
While attractive on paper, the P707 is evidently less so in reality. Although the quality of the output is average, it is much slower and much more expensive in terms of ink than its rivals. That does not even take into account the fact that the black and white printing option does not work if you are using the default cartridges (color + photo).
Lexmark has abandoned the race for speed and quality in order to invest in functions and services at low cost. The company's position is understandable, because it needs to attract those who don't use much ink and who want to be able to find a complete product but at a price that is not ruinous. This, the X6150 is the only all-in-one at less than 200€ ($200) that also has a fax. In exchange, you have to make a few concessions as regards quality, speed, and cost of ink. It's up to you to determine your priorities.
Let's start with the good news. The best selling point is that this is the only four-in-one with a document loader costing less than 250€ printer + scanner + color copier + color fax + document loader for sending long faxes and making multiple copies. Another item of good news, the color table has been revised. The photos reproduced are less yellow, and much more satisfactory. In other respects, the scanner is still one notch less than average, the print motor is slow and the cost per page is higher than that of the HP products, which are themselves far more expensive than Canon.
