Canon PIXMA TR8620a vs MegaTank PIXMA G3270: Which Printing Routine Fits?

The TR8620a manual documents automatic duplex settings for Letter/A5/A4/B5 when suitable media and software settings are used. The G3270 series Windows driver documents manual two-sided printing: print one side, reload paper as prompted and press OK. Canon’s U.S. G3270 specifications also label printing capability single-sided (simplex), so verify the exact duplex job with Canon. Separately, the TR8620a uses replaceable PGI-280/CLI-281 units and the G3270 refills GI-21 tanks. Choose by the degree of paper handling you want and your preferred ink routine; no performance or savings winner is claimed.

The buying question

Would you prefer replaceable ink units or refillable tanks, and do you need automatic two-sided printing or can you reload paper for a Windows manual-duplex job?

The TR8620a documents automatic duplex printing for specified paper sizes with suitable media/settings. Canon’s G3270 series Windows driver documents a manual two-sided workflow that pauses for paper reloading; its U.S. product specifications separately label printing capability as single-sided (simplex), so confirm the intended G3270 duplex use with Canon.

Quick verdict

Choose Canon PIXMA TR8620a All-in-One Printer (Black) if

  • You want the TR8620a’s documented automatic duplex workflow for supported sizes and suitable media.
  • You prefer replacing a depleted individual ink unit instead of refilling built-in reservoirs.

When the recommendation changes
  • If you use macOS, Canon documents automatic duplex settings for the TR8600 series but says manual duplex is unavailable there; the cited G3270 driver instructions are specifically for Windows, so confirm your operating-system workflow before buying.
  • If comparative ink yield, supply cost or lifetime cost decides the purchase, compare current genuine-supply offers against your print mix; the documented routines do not establish which costs less.

The differences that matter

Ink Refill Workflow

Canon PIXMA TR8620a All-in-One Printer (Black)

The TR8620a uses separate PGI-280 and CLI-281 ink units. Canon calls them ink tanks in its manual; when a unit is depleted, the instructions say to replace that unit with a new matching one.[1, 2, 3]

Canon MegaTank PIXMA G3270 Wireless All-in-One Printer (Black)

The G3270 has integrated ink tanks refilled from GI-21 black and color bottles. Its manual directs users to match bottle and tank colors, fill to the upper line, and reset the remaining-ink count if ink-level notification is enabled.[4, 5, 6]

What this changes: Choose the recurring routine you prefer: replace a depleted individual ink unit, or open a bottle and refill the matching built-in reservoir. These instructions do not establish comparative yield, replacement frequency, supply cost, or total cost of ownership.[3, 6, 1, 4]

The better fit depends on your priorities

Duplex Printing Workflow

Canon PIXMA TR8620a All-in-One Printer (Black)

Canon’s TR8600-series manual lists automatic two-sided printing in the Windows printer driver and macOS print dialog. It names Letter, A5, A4 and B5 as sizes suitable for automatic duplex; the media and application settings must also be suitable. The series manual index explicitly lists TR8620a.[2, 8]

Canon MegaTank PIXMA G3270 Wireless All-in-One Printer (Black)

Canon’s G3070-series Windows printer-driver instructions (the series index lists G3270) describe manual 2-sided printing: the first side prints, the user reloads the paper according to the prompt, then presses OK for the opposite side. Canon’s U.S. G3270 specifications also label printing capability “Single Sided (Simplex) Printing”; verify the intended duplex job and media with Canon.[5, 7, 4]

What this changes: This is a workflow distinction rather than a speed or output-quality result: the TR8620a has a documented automatic duplex setting for specified paper sizes and suitable media, while the G3270 series Windows driver describes a user-guided reload step. Because Canon’s G3270 product specification also says single-sided (simplex), confirm that its manual-duplex procedure covers your exact model, application and paper before relying on it.[8, 7, 4, 2, 5]

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 or user-guided manual duplex and the ink-handling routine matter to you. Neither tank design proves lower lifetime cost.

There is not enough comparable long-term price history to suggest a buy-now or wait decision. Compare current prices and checkout terms when shopping.

Limitations

  • No matched hands-on test was performed; this comparison covers published ink and duplex-printing procedures, not print speed, image quality, reliability or performance.
  • The TR8600-series manual lists Letter/A5/A4/B5 for automatic duplex and requires suitable media and application settings. The cited G3270-series driver page documents a Windows manual-duplex workflow but does not specify eligible paper sizes or media types.
  • Canon’s U.S. G3270 product specifications label printing capability “Single Sided (Simplex) Printing,” while the G3070-series Windows driver instructions describe manual two-sided printing. Confirm with Canon that the documented procedure applies to the G3270 and your intended paper/job.
  • The sources do not establish comparable page yield, ink replacement frequency, supply cost, or total cost of ownership. No savings winner is claimed.

Questions shoppers ask

Can both printers print on both sides of paper?

Canon documents an automatic duplex setting for the TR8620a through the TR8600 series manual: Letter, A5, A4 and B5 are listed, with suitable media and compatible settings. The G3270’s series Windows driver instructions describe printing one side, reloading paper at the prompt and pressing OK to print the opposite side. Canon’s G3270 U.S. specification also says single-sided (simplex), so confirm the intended job and media with Canon.

Are the ink systems interchangeable?

No. Canon specifies PGI-280/CLI-281 replaceable units for the TR8620a and GI-21 bottles for refilling the G3270’s integrated tanks. Use the supply type listed for the exact printer model.

Methodology and sources

Verified exact product identities and ink routines, then compared the TR8600-series automatic duplex settings and supported sizes with the G3070-series Windows manual reload procedure. Canon’s G3270 specification also lists simplex printing, so the intended manual-duplex job/media should be confirmed with Canon. No supply-cost, yield, speed or print-quality winner is claimed.

I compared Canon’s documented replace-versus-refill steps and automatic versus user-guided manual duplex procedures, including OS and paper-size conditions stated in the manuals.
