Stop guessing why nothing is printing

Print queue to-do list

Printing Organization Print Farm Plan School Plan

The print queue to-do list turns your whole queue into a short, prioritised checklist of physical changes to make on the floor: which spool to swap, which nozzle to change, which plate to fit, which printer to top up. For every idle machine it works out the single highest-impact move - "put PLA in this printer and it can run 16 more jobs" - so instead of scrolling 40 printers wondering why the queue is stuck, you read a list, make the changes, and unlock the next round of prints.

Turn "why is nothing printing?" into a checklist

On a busy farm the queue stalls for boring, physical reasons: a printer is loaded with the wrong material, a spool ran out, a nozzle or plate doesn't match the next job. The hard part isn't fixing them - it's finding which of your printers is the one holding up an order.

The to-do list does that finding for you. It compares your live queue against every printer's current setup and lists exactly what to change, ordered by how many prints each change would unlock. It's built for print-farm operators who'd rather work a short list than walk the floor guessing.

The one change that unlocks the most prints, per printer

An idle printer that matches nothing in the queue is wasted capacity. For each one, the to-do list finds the single change that would let it run the most queued jobs and shows it plainly: "This printer doesn't match any queue items. Put PLA in it and it would match 16 items."

You're never handed a wall of options - just the highest-impact move for that machine, with the job count it would free up, so you can work top-down and clear the biggest bottlenecks first.

Every kind of change, in one place

The list covers the physical work that actually blocks a queue, grouped into filter pills you can toggle:

  • Filament - load the material or colour the next jobs need.
  • Nozzle - swap to the nozzle size a job requires.
  • Bed type - fit the build plate the queue is asking for.
  • Refill - spools running low or already empty.
  • Idle - printers matching no queue items, with the change that would match the most.
Each pill carries a live count, so you can see at a glance there are, say, three refills and two idle printers waiting - and the printers actually blocking the queue are highlighted so they rise to the top.

Fix it from the list, then advance to the next

You don't have to leave the to-do list to act on it. Each task offers the quick actions that make sense for it - set the tag so the printer advertises the new material, nozzle or plate; assign a specific spool from your filament inventory; or jump to the printer for anything hands-on.

Complete a task and the list strikes it through and advances you to the next card, so clearing the queue's blockers becomes a steady top-to-bottom sweep instead of a hunt.

A pick list of what to grab before you start

Before you walk to the printers, the to-do list shows a "You need:" bar that adds up every material the pending changes call for - 3x PLA, a roll of Sediment Brown Bambu Lab PLA - with the colour swatch for each. If you've recorded where your spools live, it even shows the storage location, so it doubles as a pick list and you make one trip instead of five.

Hand the right task to the right person

On a team, not everyone changes every printer. Assign any task to a specific team member and it shows up under their name, ready to filter to "assigned to me" so each person sees only their work.

For the repetitive routing, set up auto-assign rules: send every refill to one person, every nozzle change to another, optionally scoped to a printer group - so tasks land with whoever owns that bench without anyone triaging the list by hand.

A daily digest, so the shift starts informed

Have the day's to-do list delivered before anyone's on the floor. Schedule a digest to a chat webhook - Discord, Slack, Teams or a custom endpoint - and to email recipients, at a time you pick, optionally anchored to your working hours.

The morning crew walks in already knowing which spools to load and which printers need attention, instead of opening the panel to find out.

Filter it down to exactly your patch

Big farm, focused view. Narrow the list to a printer group, include or hide offline and busy machines, restrict it to a set of eligible printers, or show only the groups you own. There's even a one printer per queue item mode that suggests a single printer per job - fewer spool swaps when you'd rather burn a queue down slowly.

Dial in the filters once and save them as your account default, so the to-do list always opens on the view that matters to you.

Plan availability

The queue to-do list is part of the Print Farm plan and is included on the School and Enterprise plans too. It's built for operations running many printers, where finding the one blocker fastest pays off most. The print queue itself is part of the core platform.

Frequently asked questions

It is a tab on the print queue that turns your whole backlog into a short, prioritised checklist of physical changes to make on your printers - which spool, nozzle or build plate to swap, and which printer to top up. SimplyPrint compares every printer's current setup against the queue and tells you exactly what to change to unlock the most prints.
It runs the same matching the queue uses to assign jobs to printers, but in reverse: for each printer it works out why it can't run more of the queue. The result is grouped into filament, nozzle, bed-type, refill and idle tasks. For an idle printer that matches nothing, it surfaces the single change that would match the most queued items, with the job count it would free up.
Yes. Each task offers quick actions - set the printer's tag for the new material, nozzle or plate, assign a specific spool from your inventory, or jump to the printer for anything hands-on. When you complete a task the list advances you to the next one, so clearing blockers is a steady top-to-bottom sweep rather than a hunt across printers.
Yes. A "You need" pick list adds up every material the pending changes call for, with a colour swatch for each, so you can grab everything in one trip. If you've recorded where your spools are stored, it shows the storage location next to each item too.
Yes. Assign any task to a specific team member and they can filter the list to just their own work. For routine routing you can set auto-assign rules - send every refill or every nozzle change to a particular person, optionally scoped to a printer group - so tasks land with the right person automatically.
Yes. Schedule a daily digest to a chat webhook (Discord, Slack, Teams or a custom endpoint) and to email recipients at a time you choose, optionally anchored to your working hours. The morning crew arrives already knowing which spools to load and which printers need attention.
