The overall design and packaging of the 840C is very similar to that of the 640C. Documentation is almost identical, although the USB and Parallel Quick Start guides have been split off onto two separate sheets.
The 100-sheet A4 paper feeder is functionally identical to the 640C but the implementation has been improved: rather than having to lift off the entire output tray to load the input tray with paper, the bottom of the output tray simply lifts on a hinge. HP has also extended the functionality of the hinge with a slide control that slightly angles the output tray to allow more clearance in the lower paper input tray to feed fan-fold paper. The finger-style paper supports have also been streamlined.
The AC adaptor is still external although the 840C's -brick" is much larger and is colour matched to the printer while the 640C's is black. Although the styling does vary slightly, the front mounted controls are identical to the 640C as is the presence of both parallel and USB ports.
Enough of what is the same, what extras does the 840C offer? While both printers have dual cartridge carriers and the 840C has both a CMY tri-colour and a black cartridge, the inks are formulated so that no photo cartridge is required or offered as an option. Again the printer's maximum resolution depends on the task, with 600 x 600dpi in black, and with HP's PhotoREt enabled, colour printing is at a higher resolution of 600 x 1200dpi. A large clip-off access hatch at the rear of the printer also simplifies clearing the tight -U"-shaped paper path in the unlikely event of a paper jam.
Unfortunately, we did not receive a second set of cartridges in time to carry out life testing.
In the race to output simple documents at an acceptable print quality the 840C is no faster than the 640Câ€"both output pages at a peak of 4ppm in -draft" mode. The quality of the output produced by the 840C was definitely superior as far as the simple Word document is concerned with much better character formation. Once the complexity of the printing task and quality demands are raised, the 840C convincingly forges ahead with almost twice the average output speed of the 640C. It achieved a score of 0.87ppm.
In this test, the output quality of both was similar as far as character formation was concerned although the graphics sprinkled in the document were significantly better with the 840C. On plain paper the 840C's output was also superior to the Epson 680, another $350 printer, with deeper blacks and clearer graphics.
On high-quality inkjet paper, however, the Epson turns the tables on the 840C. The 840C is quicker delivering the print at 0.16ppm and its definition is definitely superior to the 640C but the Epson 680 has much finer and less intrusive dithering. The 840C's output is also a tad oversaturated, the baby face so rosy it goes beyond -glowing health". We also found the greys to be too blue. Of course much of this can be remedied in the printer driver but we test the printers at their default colour settings, which is what the bulk of users will tend to do.
