The buying question
Do you need copy/scan and ADF document intake, or is a color print-only laser setup enough—and which paper-loading layout fits your routine?
The TR7120 combines printing with copying, scanning and a 35-sheet ADF; the LBP646Cdw is a color laser printer listed for printing only, with a larger stated cassette and a one-sheet manual-feed slot.
Quick verdict
Choose Canon PIXMA TR7120 Wireless Multi-Function Home Printer if
- You need to copy or scan originals on the printer, including multi-page sets loaded into an ADF.
Choose Canon Color imageCLASS LBP646Cdw Color Laser Printer if
- You only need printing and prefer the documented 250-sheet cassette plus one-sheet manual-feed slot.
When the recommendation changes
- If copy/scan becomes a requirement, the LBP646Cdw's print-only function is a mismatch; if those functions are unnecessary, the TR7120's multifunction feature may not affect the decision.
