Printing The Canon PIXMA TR7820 prints using inkjet technology, which sprays liquid ink onto the paper from a moving head. It has very good text quality, though not quite as good as the best printers. Text printing speed is typical, 5 pages took 25 seconds, costing 9.3 cents per page. It prints color graphics well enough for most purposes, such as school reports, costing 31.6 cents per page. It prints very good photos on glossy paper that most people would be happy with. It has auto-duplex printing to print both on sides of the page. The multi-color ink cartridge must be replaced when a single color runs out. The capacity of the main paper tray is 100 sheets, a typical amount. There's a second input tray that can hold another 100 sheets.
Scanning and Copying This is a multi-function printer. Scanning performance was very good, fine for general-purpose scanning. It has an Automatic Document Feeder (ADF) for easily scanning/copying a stack of pages.
Controls and Display The printer has a color display screen 2.6-inch diagonal size, touch-input capability, and can be tilted.
Connectivity and Networking It can print documents via USB and WiFi. We found it more tedious than usual to setup the WiFi connection on this printer.
Cost of Ownership and Ink When this page was last updated, the printer's purchase price was about $170, low for a all-in-one cartridge inkjet printer. Printing uses up ink and the costs add up over time. This printer uses two (2) cartridges. When the ink runs low, you replace the empty cartridge. The inks we used in testing were the Canon CL-286 Color, and PG-285 BK cartridges—at the time, the prices were $30 and $19 respectively. We estimate each cartridge of ink to last at least 8 months—a short time—following a typical monthly printing amount of 19 text and 8 graphic pages. After 2 years of typical use, we estimate your total equivalent cost to be $302—low for a inkjet. The estimated yearly cost is $66, which is typical for a inkjet type of printer. The theoretical total cost after 5 years is $500. The printer needs a moderate amount of space .
