Canon PIXMA TS3720 vs TR8620a: Choose by Duplex Handling and Ink Replacement

These Canon models differ in two everyday routines. The TS3720 is specified for single-sided printing, with a Windows-driver manual duplex option for plain paper that requires reloading and is unavailable with Borderless, Tiling/Poster, or Booklet layouts. The TR8620a lists automatic two-sided printing for supported Letter/A5/A4/B5 sizes and suitable media; its cited Windows driver documents its standard Duplex Printing setting for Plain Paper and selected layout modes; Booklet has a separate two-sided setting. The TS3720 uses black and color FINE cartridges; the TR8620a uses five individual tanks. No print-quality or ink-cost winner is established.

The buying question

For household printing, would you rather reload plain sheets for an occasional TS3720 Windows-driver duplex job or use TR8620a automatic duplex only with a supported paper size and suitable media, while choosing between a black-plus-color cartridge pair and five separately replaceable tanks?

The TS3720 is listed for simplex printing, though its Windows driver documents manual duplex on plain paper: print one side, reload the sheets, then print the reverse. That manual option is unavailable with Borderless, Tiling/Poster, or Booklet layouts. The TR8620a lists automatic two-sided printing; Canon lists Letter, A5, A4, and B5 as suitable sizes and says the media type must suit automatic duplex. In the cited Windows driver, the standard Duplex Printing setting specifies Plain Paper and the Normal-size, Fit-to-Page, Scaled, or Page Layout modes; Canon documents Booklet as a separate two-sided mode. For ink replacement, the TS3720 uses separate black and color FINE cartridges, while the TR8620a uses five individual tanks: pigment black, black, cyan, magenta, and yellow.

Quick verdict

Choose Canon PIXMA TS3720 Wireless All-in-One Printer (White, 6671C022) if

  • Most print jobs are one-sided, and for an occasional duplex job you can use plain paper and an eligible TS3720 Windows-driver layout, then reload the sheets yourself.
  • You prefer a black cartridge plus one color cartridge rather than five individual ink tanks.

Choose Canon PIXMA TR8620a Wireless Home Office All-in-One Printer (Black, 4451C032) if

  • You want automatic two-sided printing for Letter, A5, A4, or B5 jobs using media suitable for duplex; the cited Windows driver specifies Plain Paper for its standard Duplex Printing setting; Booklet has a separate two-sided mode.
  • You prefer to replace the individual ink tank Canon identifies as depleted instead of using a black-and-color FINE cartridge pair.

When the recommendation changes
  • If duplex printing is occasional and the job is plain paper in an eligible Windows layout, the TS3720 has a documented manual option but requires reloading. If you want the printer to turn pages automatically, the TR8620a supports automatic duplex for Letter/A5/A4/B5 with suitable media; its cited Windows driver documents the standard Duplex Printing setting for Plain Paper and Normal-size, Fit-to-Page, Scaled, or Page Layout; Booklet is a separate two-sided mode.
  • If you are comparing supply budgets, check current cartridge and ink-tank prices and the manufacturer’s yield conditions for your own print mix. This comparison does not establish lower ink cost, longer life, or a cost winner.

The differences that matter

Duplex Print Workflow

Canon PIXMA TS3720 Wireless All-in-One Printer (White, 6671C022)

Canon lists the TS3720 for single-sided (simplex) printing. For plain paper, the TS3700-series Windows driver manual documents manual duplex: print one side, reload the sheets as prompted, then print the reverse. The driver disables this manual-duplex option for Borderless, Tiling/Poster, or Booklet layouts.[1, 2, 3]

Canon PIXMA TR8620a Wireless Home Office All-in-One Printer (Black, 4451C032)

Canon lists Auto 2-Sided (Duplex) Printing for the PIXMA TR8620a. Its TR8600-series manual identifies Letter, A5, A4, and B5 as suitable sizes and says the loaded media type must suit automatic duplex. In the cited Windows driver, the standard Duplex Printing setting specifies Plain Paper and Normal-size, Fit-to-Page, Scaled, or Page Layout; Canon documents Booklet as a separate two-sided mode.[5, 6, 8, 9]

What this changes: For frequent two-sided documents, the TR8620a can avoid the TS3720 Windows procedure’s manual reload when the job uses a supported size and suitable media. Canon lists Letter/A5/A4/B5 sizes; in the cited Windows driver, the standard Duplex Printing setting specifies Plain Paper and Normal-size, Fit-to-Page, Scaled, or Page Layout. Canon documents Booklet as a separate two-sided mode. For occasional plain-paper duplex, the TS3720 Windows driver requires reloading and does not offer manual duplex with Borderless, Tiling/Poster, or Booklet layouts.[1, 3, 5, 6, 8, 9]

Ink Replacement Workflow

Canon PIXMA TS3720 Wireless All-in-One Printer (White, 6671C022)

Canon’s TS3720 specifications identify PG-275 black and CL-276 color ink cartridges; its TS3700-series manual describes a black FINE cartridge and a color FINE cartridge.[1, 2, 4]

Canon PIXMA TR8620a Wireless Home Office All-in-One Printer (Black, 4451C032)

Canon lists five individual TR8620a ink tanks: one pigment black (PGBK), one black (BK), cyan, magenta, and yellow. Its TR8600-series manual says to remove and replace the tank where the ink runs out.[5, 6, 7]

What this changes: The TS3720’s replacement choice is between its black and color cartridges, while the TR8620a instructions identify which separate tank has run out. This helps buyers decide which supplies to keep on hand; cartridge count alone does not show which system costs less or lasts longer.[1, 4, 5, 7]

The better fit depends on your priorities

Best for your routine

Printing frequent two-sided plain-paper documents in Letter, A5, A4, or B5 without reloading sheets between sides

Best fit: Canon PIXMA TR8620a Wireless Home Office All-in-One Printer (Black, 4451C032)

Based on listed features, not comparative testing.

Canon lists automatic duplex for the TR8620a and identifies Letter/A5/A4/B5 as suitable sizes. For the cited Windows driver’s standard Duplex Printing setting, use Plain Paper and the documented layout modes; Canon documents Booklet separately as a two-sided mode. The TS3720’s documented Windows-driver method is manual and requires paper reloading.

Based on listed features, not comparative testing.

Canon lists the TS3720 with separate black and color FINE cartridges and single-sided capability. The TR8620a’s automatic duplex and five-tank system may not match a buyer who prefers that cartridge arrangement.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Any price difference should be weighed against whether automatic duplex and five individual tanks fit your routine. This research does not establish cartridge cost, page yield for an individual household, or total ink spend.

There is not enough comparable price history here for a buy-now or wait recommendation.

Limitations

  • Duplex workflows are bounded by the cited manuals. The TS3720 procedure is for Canon’s Windows driver, Plain Paper, and not Borderless, Tiling/Poster, or Booklet layouts. TR8620a automatic duplex is listed for Letter/A5/A4/B5 with media suitable for duplex; its cited Windows driver specifies Plain Paper and Normal-size, Fit-to-Page, Scaled, or Page Layout for the standard Duplex Printing setting; Booklet is a separate two-sided mode. Other OS/app workflows and compatible-media details remain subject to the print dialog and manual.
  • Ink-system configuration does not establish cartridge price, per-page cost, household page yield, or print longevity. Compare current supply offers and the manufacturer’s test conditions for your expected print mix.
  • No controlled head-to-head test was used, so this comparison does not rank print quality, speed, reliability, or real-world ink consumption.

Questions shoppers ask

Can the TS3720 print on both sides of a page?

Canon lists the TS3720 for single-sided printing, but its TS3700-series Windows driver documents manual duplex on plain paper: print one side, reload the sheets when prompted, and print the reverse. This option is unavailable with Borderless, Tiling/Poster, or Booklet layouts. The TR8620a lists automatic duplex for Letter, A5, A4, and B5 with media suitable for duplex; in the cited Windows driver, the standard Duplex Printing setting specifies Plain Paper and Normal-size, Fit-to-Page, Scaled, or Page Layout; Canon documents Booklet as a separate two-sided mode.

How do the ink supplies differ?

The TS3720 uses a black FINE cartridge and a color FINE cartridge. Canon lists five individual tanks for the TR8620a—pigment black, black, cyan, magenta, and yellow—and its manual says to replace the tank that has run out. This describes replacement setup, not which printer costs less to run.

Which one has lower ink cost?

These specifications do not establish a cost winner. Compare the current price and stated yield of each compatible cartridge or tank under the manufacturer’s test conditions, and consider your mix of black-and-white and color pages.

Methodology and sources

Compared the exact models’ documented duplex print procedures and cartridge/tank replacement arrangements. For duplex, checked Canon’s model-linked paper-size/media guidance and Windows-driver layout limits for both sides. No speed, print-quality, ink-cost, or reliability winner was inferred.

AI-assisted research organized Canon’s published specifications and instructions into a conditional buyer guide; no hands-on test was performed.
