Open your event, tap Configure Printers, tap the printer you want, and find Print Size under Settings. The row shows the current size on the right; tap it to open the full list.

The size belongs to that one printer entry, not to the app and not to the physical machine. Add the same printer twice and each entry carries its own size — that's how one DS620A can run 4×6 for one template and 6×8 for another. See Managing Multiple Printers.

Everything else on that screen — margins, strips per sheet, cutting, finish, quality and sharpening — is covered in Print Settings Explained.

Print sizes aren't a generic list. Each model produces its own set, and a few sizes need a firmware version new enough to know about them.

The "starts on" column is what a printer prints before anyone touches the setting. It's worth a second look on the 8-inch models: a freshly added DS820A or DS80 prints 8×10, not 4×6, so a template designed for a 4×6 booth print will be fitted onto a much larger sheet until you choose otherwise.

Where a size is listed as needing firmware, it appears once Snappic can read the firmware off the connected printer — so it won't be in the list while that printer is unplugged.

Each size is a physical sheet the printer cuts from the roll. Choosing one is choosing what a guest walks away holding.

These are large-format printers, and every size is 8 inches across the paper — 8×4 through 8×12 vary only in how long the sheet is. The short ones (8×4, 8×5, 8×6) give you a wide panoramic shape; 8×8 (square) is square; 8×10 and 8×12 are the poster-sized prints these machines exist for. The DS820A adds 8×7 and 8×9; the DS80 and DS80DX don't offer those two.

The QW410 is the compact model, and its sizes come in two widths. 4×4 (square), 4×6 and 4×8 print on 4-inch-wide paper; 4.5×4.5 (square), 4.5×6 and 4.5×8 print on 4.5-inch-wide paper. Which of the two groups you can use depends entirely on the roll you've loaded — see below, because this is the model where it bites hardest.

This option is listed as 4×6 — 2 per sheet, and it's available on the 6-inch models only. It prints a 6×8 sheet carrying two 4×6 panels, and the printer cuts the sheet between them, so two finished 4×6 prints come out.

Three things about it are worth knowing before you switch it on.

Both panels are the same photo. This isn't a way to fit two different guests' prints onto one sheet. It prints one image twice — the classic "one for you, one for the album".

One copy gives you two prints. Snappic works out how many sheets it needs from how many copies were asked for, so a single copy still produces one sheet, and that sheet still comes out as two identical 4×6s. Ask for two copies and you get exactly one sheet. Ask for three and you get two sheets — four prints, one of them spare.

That interacts with print limits, which count copies rather than prints: a one-copy job costs one against an event's limit and hands the guest two photos. See How Event Print Limits Work.

It needs 6×8 media. The panel is a 6×8 sheet, so a 6×4 roll can't produce it. A 6×8 or 6×9 roll can.

The reason to reach for it is media economy. On a 6×8 roll, this is how you get two 4×6 prints out of one sheet rather than one — and it halves the number of sheets, and the number of print cycles, for the same number of prints.

A print size is only real if the roll in the printer can produce it. These are the combinations that work.

Two rows in that table catch people out. A 6x4 (PC) roll produces one size and one only — no 6×6, no 6×8, and no 2-up. And on the QW410, a 4.5-inch roll refuses the 4-inch sizes: load 4.5x6 and 4×4, 4×6 and 4×8 all become unavailable, even though the printer supports them.

That second one has a sharp edge, because 4×6 is also the size a QW410 starts on. A QW410 entry you've never set a size on will fail every job while a 4.5-inch roll is loaded. Choose 4.5×6 or 4.5×4.5 and it prints.

Sticker media follows whatever its base roll can do — a 6x8 (A5) Sticker roll produces the same sizes as plain 6x8.

While a printer is connected, Snappic reads the loaded roll and marks the sizes it can't produce. Open the Print Size row and any incompatible option carries a note underneath it in orange — "Not available with the loaded 6x4 (PC) media", naming the roll it actually found.

Marked options are not removed, and nothing stops you selecting one — you may be about to change the roll. But it means you have to open the row to see the warning: the settings screen itself just shows the size you've chosen, with no flag on it.

This is the single most common cause of a setup that worked yesterday failing today. If you change media mid-event, update the print size to match before you carry on, and run a Test Print.

You can open and edit a Direct USB printer's settings whether or not the printer is plugged in — but with nothing to ask, Snappic can't show that unit's real list. An unconnected entry shows a general 6-inch list instead: 4×6, 6×6 (square), 6×8 and 4×6 — 2 per sheet, whatever model the entry actually points at.

Two consequences follow. Firmware-dependent sizes — 6×9 and 4.5×6 on a DS620A, 6×6 on a DS40 or DS-RX1 — won't be listed until the printer is connected. And a size shown on an unconnected entry isn't a promise that the printer offers it.

These look nothing alike on the day, so they're worth telling apart.

The two can chain: if a substituted size doesn't suit your roll either, you get the media failure — which is exactly what an untouched QW410 does on 4.5-inch media.

This catches people out, so it's worth stating plainly: Print Size drives strip jobs too. It isn't a standard-prints-only setting. Change the size on a printer that handles strips and your strips change with it.

The size sets the sheet your strips are laid onto, and Strips Per Sheet divides that sheet between them. Two strips on a 4×6 sheet gives the classic pair of 2×6 strips; four on a 6×8 sheet gives four 2×6 strips from one sheet. If you've never chosen a size, strips use 4×6.

Two knock-on effects:

So if you adjust a size and your strips start coming out wrong, the size is the first thing to check — and Test Print after any size change on a strips printer, not just on a standard one.

Test Print is the check that actually covers size. It sits on each printer's settings screen and prints a card through the same rendering your guests' prints use, at the size and settings that printer currently holds — so what comes out of the machine is the answer. Where a printer can receive both kinds of job you get two buttons, Standard and Strips. Run one after any size change, and again whenever you change media.

Printer Check runs by itself when you start an event, but it's answering a different question. It reports templates that no configured printer is allowed to print ("No configured printer can print these templates: 3 stills, 2 GIFs."), printers it couldn't find, and printers reporting a problem such as a cover open. You can Continue Anyway or choose Review Printers.

Why isn't the size I want in the list?

Cause: Either that model doesn't produce it, or it's one of the firmware-dependent sizes and the printer isn't connected for Snappic to check.

Fix: Connect the printer and reopen its settings. If the size still isn't listed, check the model table above — you may need a different printer for that size.

Why is a size marked "Not available with the loaded media"?

Cause: The roll currently in the printer can't produce that size. The note names the roll Snappic found.

Fix: Either choose a size the roll can produce, or load media that suits the size you want. You can still select a marked size — but jobs will fail until the media matches.

Why did a job fail saying the loaded media can't print my size?

Cause: The size on that printer entry and the roll in the machine don't agree — usually because the media was changed and the size wasn't.

Fix: Update the print size to match the roll, run a Test Print, then retry the failed job from the print queue.

Why are my prints coming out a different size than I set, with no error?

Cause: The size was chosen while the printer was unconnected, and that model or its firmware doesn't actually support it. Snappic substitutes the model's starting size and prints — 4×6 on the 6-inch models and the QW410, 8×10 on the 8-inch ones. Nothing is reported, because from the printer's point of view the job succeeded.

Fix: Connect the printer, reopen its settings, and choose the size again from the list it shows. Confirm with a Test Print.

Why did my strips change when I only changed the print size?

Cause: The print size drives strip jobs as well as standard ones — it sets the sheet the strips are laid onto.

Fix: Set the size that suits your strips, then Test Print to confirm. If you need different sizes for strips and standard prints, add the printer twice with different settings — see Managing Multiple Printers.

Why can't I find Cut Strips Apart any more?

Cause: The strip cutter only works on a 4×6 sheet, so the row disappears at any other size — including 4×6 — 2 per sheet.

Fix: Set Print Size back to 4×6 and Strips Per Sheet to 2. See Print Settings Explained for the full set of conditions.

Why is only one 4×6 printing when I chose 2 per sheet?

Cause: The job went to a printer entry that isn't set to that size. Sizes belong to individual entries, so if you have the same printer added twice, only the entry you changed is on 2-up.

Fix: Work out which entry is receiving the template and set the size there — see Routing Templates to Printers. If the size is right on that entry, check its media is 6×8 or 6×9; on a 6×4 roll the job fails rather than printing a single 4×6.

Why is my 2 per sheet giving me two of the same photo?

Cause: That's what the size does — it prints one image twice on a single sheet and cuts it apart. It isn't a way to combine two different photos.

Fix: Nothing to fix. If you want one print per guest rather than two, use plain 4×6.

Why doesn't this printer have a Print Size at all?

Cause: Either it's not a Direct USB printer, or it's a Citizen CW-01, which produces one size and so has nothing to choose.

Fix: On AirPrint, set the size on the unit itself. On a print server, set it on the server. See Managing Multiple Printers.
