The test procedure was more or less the same as the one we used for our desktop printers.
The only difference is in our method for calculating cost per page. The cost per page for desktops does not apply here. For these devices, it seemed more sensible to find the cost per photo. Afterwards, you can compare this with the prices charged by your usual photo developer.
The tests consisted of a series of prints in monochrome and color, each with the same level of precision in the characters, color block unity and color rendering.
As usual, we also tested the time taken to print one page and a series of pages, both in monochrome and in color.
