The same question has startled me for a long period of time, after examining both the printers (HP Officejet 4650 and Canon Office and business MX922).
Both these printers are very similar to each other. here is a comparison between these two
Top features of HP Officejet 4650 are:
- Type: Inkjet
- Speed: Print Black up to 9.5 pages per minutes and color up to 6.8 pages per minute.
- Function: Print, Scan, Copy and Fax.
- Connectivity: Apple's AirPrint,Cloud Print, Hassle-free mobile printing, Wireless WiFi 802.11.
- LCD Display: 2-inch high-resolution mono LED.
- Double-sided printing that allows you to print on both sides of the paper, so the usage of paper can be reduced by up to 50%.
Top features of Canon Office and business MX922 are:
- Type: Inkjet
- Speed: Print Black up to 9.7 pages per minute and color up to 5.5 pages per minute.
- Function: Print, Scan, Copy and Fax.
- Connectivity: Wireless LAN, Google Cloud Print, Apple's AirPrint, Wireless Printing as well as Mobile Device Printing.
- LCD Display: 2 Line Display.
- Equipped with 35 sheet Automatic Duplex Document Feeder that allows you to Scan, Copy and fax Multiple Documents at a glance.
- Auto-Duplex Printing which allows us to print on both sides of sheet quickly.
After comparing both these printers, i would like to suggest canon office and business MX922 over HP officejet 4650 because HPofficejet 4650 is lightweight and doesn't have a strong build.
Canon MX922 is much faster than Officejet 4650.
