HP DeskJet 3720: Ink Printer in Mini Format in the Test

The DeskJet 3720 Announces HP as the world’s smallest multi function printer. Whether it is small or well, the test revealed.

Superlatives are always difficult to prove. The fact is that HP with the DeskJet 3720 has a very compact multifunction printer. He is suitable especially for users who want to print and scan from the mobile device. For this the manufacturer brought out at the same time the app “Social media snapshot”. With her photos from social networking sites like Facebook or Instagram can customize and print. The app is there free for Android, iOS, and Windows in the respective stores for downloading. The right photo paper is self-adhesive, can detach themselves again from the surface and has a measure of 10 x 13 cm. Not included in the combined printer, it costs approximately $10 for 25 sheets.

The biggest advantage of the HP DeskJet 3720 lies in its construction. He finds a place even in the smallest space. Forward, you must however include more space, because it used the device as a tray. The compact dimensions have need getting used to scan unit result. The feeder only one sheet can be process, which must be also very properly inserted. Digitalizing fall so flat. In addition, slowly working the HP model in all disciplines and creates costly page prices. Thus, it is suitable only for rare operations. Rather a fun article as a classic tool for printing, scanning and copying.

Indeed, the HP DeskJet 3720 reveals little room on the desk. He owes that first and foremost the scanner that is reduced to the minimum. The manufacturer calls the technology “Scroll-Feed”. These are a kind of Input scanner, whose single reading line is across the width of the device. He comes to the width of a DIN-A4-Blatts, thereby saves himself at the same time the size of the usual glass surface.

Despite the small crowd, a small font display on the DeskJet 3720 accommodates HP. It displays the number of copies and symbols for the cartridge filling levels. There are eight buttons are marked only by symbols on the control panel. Black and white and color copies have dedicated buttons – that’s good. In addition to the USB port multifunction printer via Wi-FI can be connect to the home network and has also a WiFi direct function. The device prints, scans, and copies. A fax is not provided. In the narrow tray 60 sheet space for maximum. An own tray saved HP. This must be the footprint.

Consumption – small combination cartridges

The ink cartridges are as small as the device. They belong to the series of 304 with a built-in print head. The Starter equipment is quickly empty printed in the test. Also in the replacement of XL variants, not excessive content is in there. So we calculate with 8.3 cents for the black and white and 8.7 cents for the coloured sheet also salted page prices. Can be only by participating in the instant ink program of manufacturer’s something lower. But even with the cheaper ink replenishment, the device only for occasional use applications. The power consumption of the HP DeskJet 3720 is unobtrusive. He have but to write to a minus: the off switch disconnects the multifunction printer not completely from the power supply. The meter displays still 0.2 Watts when switched off – an unnecessary consumption.

Speed – very leisurely way of working

The compact design takes its toll. Because the HP DeskJet 3720 works very slowly. This is reflected in the test with more parents: so we wait 10 colored A4 pages from Acrobat over five minutes. Also an A4 photo with 4:35 minutes long. We need more patience when scanning. This is first and foremost on the feeder, which correctly handles only absolutely precisely defined templates. Here already the preview with 22 seconds takes almost as long as a full color scan (24 seconds). At all readings are very similar. They show that the unit only for the occasional scan is intended. This also applies to the copy. The device allows only up to 9 copies in one piece. Also, it takes a minimal sloppily drawn sheet now evil. It is advisable not to wait for the operation, but to cancel immediately.

Quality – not a borderless

For an ink multifunction printer, which is especially suitable for photos from the social networks, it is surprising that he can create any borderless pictures. In pure text printing HP DeskJet results 3720 for ordinary, albeit with minimal ink points around the letters. The colours are harmonious, however, and also with skin tones of course remain. The samples have a relatively strong red cast, but sharp fall out. Because the Input scanner is getting, he caused some misses in the test. There is a devaluation as a whole, because in these cases, the scans were useless. The copies suffer something under the scan unit. You will easily something goes wrong. Also color copies fail to light, which lost details
