Advantages: Nice colors, convenient software, excellent printing on dense paper

Disadvantages: Large dimensions

Connection of the printer and also installation of the software and drivers have not called any difficulties.

This printer differs by impressive dimensions of the body. The solid dimensions can entail some problems with accommodation of this printer on a working table. It is rather strange, that in so volumetric body was not found places for accommodation of a rather compact power supply unit.

During testing the driver of version 12.2 was used. Set-ups allow selecting a type, orientation and format of a paper, and also amount of copies. There are options of mirror printing, turn on 180 degrees, printing of pages in the return order, and also process of scaling of a printed image as on a specific format of a paper, and arbitrary. If necessary it is possible to use a mode of manual double side printing for a fastening of sheets on the long or short side. There are options of printing of two or four pages on one sheet, and also large images (posters) on 4, 9 or 16 sheets.

Three gradation of printing quality (draft, normal and best) are stipulated; for want of use of some types of carriers the mode of draft-quality printing becomes inaccessible. For use of a photocartridge it is necessary to activate an appropriate option. In additional tunings there are options of forced printing in gradation gray and optimization of images for transfer by fax.

Together with the driver of the printer the service program HP Toolbox v2.4 is installed, with the help of which can call a help, to initiate procedures of printing of trial page, calibration etc.

Quality of prints is enough good.

The draft-quality print differs by good brightness of the text, however on some lines the numerals are reproduced with declination to the left or to the right.

On a print, executed on a usual paper, is appreciable pixelity. The image on a paper with the improved cover has brightness and contrast slightly. On photographic paper an image i
s bright, saturated and with optimum contrast.

The printer works with moderate noise level.

The loading of the processor for printing of the text made 5-10 %, for printing the graphics - 6-12 %.

HP DeskJet 640C is supplied with the convenient software and demonstrated high efficiency, greatest an exactitude of colors and quite good quality of prints.

Thus, HP DeskJet 640C well will approach for operating printing of the text and mixed documents as on usual, so on special grades of a paper. Rather useful there can be a mode of preliminary survey of pages sent on printing. Besides this printer allows to receive the bright and saturated prints on a dense and invoice paper (cards, envelopes etc.).
