HP Designjet T770 Ink Cartridges

HP T770 Printer Review

The HP Designjet T770 inkjet printer comes in a few different configurations, with the primary difference being the size of the wide-format device. Buyers can choose the 44-inch or 24-inch version, based on the specific needs of the business. Each size is available as a base model or with a built-in hard drive, which increases the storage space significantly. Companies looking to handle advertising in-house or that specialize in fields such as engineering and CAD will benefit from the addition of the T770 to the office.

When it comes to output rates, line drawings can print at a speed of 28 seconds per page, while more complex, color documents take much longer. In Fast mode, up to 445 feet can be printed in an hour, but this mode will not generate the best quality. Rather, Best mode will call for more dots per inch of HP T770 ink, creating a resolution of 2400x1200 dpi at a speed of about 33 feet per hour. This rate is calculated using the feed roll of paper rather than sheets.

The matte black HP T770 ink is pigment-based, while the cyan, magenta, yellow, gray, and photo black printer ink is all dye-based. There are three printheads, which have nozzles attached for ejecting the Designjet T770 ink in dots ranging from 6-9 picoliters. The built-in color layering technology then ensures that the colors blend together to create accurate, true-to-life images and drawings.

Both formats of the T770 are bulky, with the 24-inch version weighing 134.5 pounds and measuring 49.7x27.5x41.3 inches, and the 44-inch option weighing 180 pounds and measuring 69.7x27.6x41.3 inches. There is a small display that will keep track of the progress of tasks as well as show error messages and settings. There is also a panel on the front corner that pops open and houses the six HP T770 ink cartridges. The slots are color-coded so the correct printer ink is easily installed. Each printhead is designated to two Designjet T770 ink cartridges.

Overall, offices with needs that require large-format printing will be happy with the production rate and quality of the HP Designjet T770 inkjet printer. Its wheels make it easy to move around and the quality makes for excellent signage.
