Printing at an onsite contest

At a physical venue, contestants can send documents to a printer in the room without any network access of their own: the console registers the printer, a printer client running at the venue authenticates with the printer's secret and collects jobs one at a time, and the contest is bound to that printer.

Printing needs a plan that grants at least one printer. Without it the Printers tab is not in Settings and the Printer field is not on the contest — see Why a section is missing. Registering printers needs permission to configure the space; binding one to a contest needs permission to write contests.

Set printing up

Go to Settings → Printers and choose Create printer.
Give it a name — this is the label organizers and participants see, so name it after the room or the machine rather than the model.
Save. A secret is generated with it.
Open the printer again with Edit to read the secret. It is shown only here, and it is what the printer client uses to authenticate.
Install and run the printer client at the venue with that secret. It connects to Eolymp, reports its state, and receives jobs.
Open the contest, go to Settings → Other, and pick the printer in the Printer field.

A contest is bound to one printer. More on registering and maintaining them is in Printers.

While the contest runs

The printer list shows each printer's state:

State	What it means
Offline	The client is not connected. Nothing will print
Ready	Connected and idle. Jobs are handed to it
Busy	Working on a job

A printer is given work only while it reports Ready, and only one job at a time — the next is handed over after the client reports the previous one finished. Jobs move through Pending → Printing → Complete, or end as Error or Cancelled. The pending queue has a cap, so a printer that has stopped answering cannot accumulate work indefinitely.

If nothing is coming out, look at the state first. Offline is the printer client, not the contest: restart it at the venue and check the secret it was given.

Printing the problem set

Printing the statements for the contestants is a different job and does not go through the printer at all — the contest's Problems tab exports the whole set as one PDF booklet, which you print and photocopy in the ordinary way. See Contest problems.
