Canon PIXMA TR7120 vs TS3720: Which Printer Fits Your Print and Scan Routine?
For the Windows printer drivers covered by Canon’s manuals, the TR7120 documents automatic duplex on Letter/A4, while the TS3720 offers manual duplex with a sheet-reload step for supported settings. The TR7120 also has a documented ADF for multi-page originals; Canon lists a flatbed for the TS3720 without stating an ADF capacity. The cited driver manuals do not establish macOS, mobile, or other app behavior.

The buying question
In Canon’s documented Windows printer-driver workflows, do you want the TR7120’s automatic duplex for Letter/A4, or is the TS3720’s manual-reload option enough? Does the TR7120 ADF matter for your scan routine?
Canon’s TR7100-series Windows driver documents automatic duplex for Letter/A4 on the TR7120; Canon’s TS3700-series Windows driver documents manual sheet reloading for the TS3720 under supported settings. Other operating-system or app paths were not established. Separately, the TR7120 has a specified 35-sheet ADF while Canon lists a flatbed scanner for the TS3720 without an ADF capacity.
Quick verdict
Choose Canon PIXMA TR7120 (White, 7178C002) if
- You use the documented TR7100-series Windows printer driver and want automatic two-sided printing on Letter or A4.
- You regularly scan or copy stacks and want a documented 35-sheet ADF for plain paper, or up to five legal-size sheets.
Choose Canon PIXMA TS3720 (White, 6671C022) if
- You use the TS3720 Windows printer driver’s manual-duplex option for supported print settings and are comfortable reloading sheets.
- Most scans are individual originals that you can place on the TS3720 flatbed; Canon lists its scanner type as flatbed. If another OS or app matters, confirm its duplex path with Canon.
When the recommendation changes
- If you use Canon’s Windows driver and two-sided printing is frequent, the TR7120 automatic Letter/A4 workflow avoids the documented manual reload; other OS/app workflows are not established here.
- If your originals are usually one page at a time, an ADF may not change your routine; recurring stacks make the TR7120 feeder more relevant. Neither cited source set establishes automatic duplex scanning, so treat that separately.
The differences that matter
Duplex Print Workflow
Canon PIXMA TR7120 (White, 7178C002)
Canon lists duplex printing for the TR7120. The cited TR7100-series Windows printer driver documents automatic duplex without turning the sheet over and limits that workflow to Letter or A4; other operating-system or app workflows are not established here.[1, 2]
Canon PIXMA TS3720 (White, 6671C022)
The TS3720 specification lists single-sided (simplex) printing. Its TS3700-series Windows printer driver manual separately documents manual duplex: after the first side, reload the sheet as prompted and press the printer OK button. That manual option is limited to plain paper and listed layouts; other operating-system or app workflows are not established here.[3, 4]
What this changes: In the cited Windows printer-driver instructions, the TR7120 can turn supported Letter/A4 sheets automatically, while the TS3720 manual option asks the user to reload sheets for the other side. These documents do not establish workflows in other operating systems or apps, and they say nothing about measured print quality or throughput.[1, 2, 3, 4]
Multi Page Scan Workflow
Canon PIXMA TR7120 (White, 7178C002)
Flatbed plus ADF; Canon specifies capacity for 35 plain-paper sheets or 5 legal-size sheets. The ADF accepts originals up to legal size.[1]
Canon PIXMA TS3720 (White, 6671C022)
Canon lists a flatbed scanner with an 8.5 x 11.7-inch maximum document size. The TS3720 specifications do not identify an ADF, so confirm with Canon if feeder loading is a purchase requirement.[3]
What this changes: For a stack, the TR7120 documents an ADF with stated capacity. The TS3720 listing identifies a flatbed, which suits individual originals placed on the glass; its support page does not provide ADF capacity. This physical scanner comparison does not establish software or driver support on every operating system.[1, 3]
Best for your routine
Frequent two-sided Letter/A4 printing from the documented Windows printer-driver workflows with fewer manual paper steps
Best fit: Canon PIXMA TR7120 (White, 7178C002)
Based on listed features, not comparative testing.
Canon documents automatic Letter/A4 duplex for the TR7120 in its TR7100-series Windows printer driver, while the TS3720 Windows driver instructions require reloading sheets for manual duplex. Other OS/app paths are not established.
Scanning or copying recurring stacks of originals
Best fit: Canon PIXMA TR7120 (White, 7178C002)
Based on listed features, not comparative testing.
Canon specifies a 35-sheet plain-paper ADF for the TR7120. TS3720 specifications identify a flatbed and do not state feeder capacity; verify with Canon if an ADF is essential.
Occasional duplex printing through Canon’s documented Windows drivers and one-page-at-a-time scanning
The better fit depends on your priorities
The TS3720 Windows driver documents manual duplex for supported settings, and its flatbed can suit individual originals. Confirm duplex behavior with Canon if using another operating system or app.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
Evaluate current offers at checkout against whether automatic duplex printing and feeder-assisted scanning will be used; this comparison does not quantify the value of those features.
Current history is insufficient for a timing recommendation. Compare the live seller, condition and offer at checkout.
Limitations
- This comparison uses Canon’s published product specifications and driver manuals; Pickoryx did not conduct hands-on testing or compare print/scan quality, speed, reliability or ease of use.
- The TR7120 Letter/A4 automatic-duplex limit and TS3720 manual reload/layout instructions come from their respective Windows printer-driver manuals. The sources do not establish equivalent behavior in macOS, mobile apps, or other software; confirm with Canon if those paths affect your choice.
- Canon lists the TR7120 scanner as flatbed plus ADF with stated feeder capacity. The TS3720 support specification lists a flatbed and does not give ADF capacity; confirm exact-model support with Canon if an ADF is essential.
- The sources do not establish automatic duplex scanning for either model. Do not treat two-sided printing as two-sided scanning.
- No purchase-timing or longer-term-low conclusion is drawn from the available price history.
Questions shoppers ask
Does the TS3720 print on both sides?
In Canon’s TS3700-series Windows printer driver, the manual-duplex option prints one side, then prompts you to reload the sheet and press the printer’s OK button. Canon limits the option to plain paper and supported layouts. The cited instructions do not establish what another operating system or app offers; check with Canon if that is your setup.
What changes when scanning several pages?
The TR7120 has a flatbed and a documented ADF capacity of up to 35 plain-paper sheets or five legal-size sheets. Canon lists the TS3720 scanner as a flatbed with an 8.5 x 11.7-inch maximum document size; its specification does not state an ADF capacity, so confirm with Canon if a feeder is required.
Does the TR7120 scan both sides automatically because it prints both sides?
The cited TR7120 specification/manual establish automatic two-sided printing and an ADF, but do not establish automatic duplex scanning. Confirm exact-model duplex scanning with Canon if you need to capture both sides of originals.
Methodology and sources
The comparison separates the Windows printer-driver instructions for two-sided printing from the hardware-supported original-handling workflow for scanning. The Canon driver manuals document an automatic TR7120 path for Letter/A4 and a manual TS3720 reload path for supported settings; other OS/app paths are not established. Print duplex and scan duplex are treated as different functions, with no measured-performance inference.
