Device detail

Inspect a single fiscal printer — check cash balance, run X and Z reports, edit fiscal settings, and review the command history for that device.

The Device detail screen is where you manage one specific fiscal printer. Open it by tapping a device tile on the Devices tab. From here you can check the printer's status, run daily fiscal operations, change settings, and review what commands have been sent to it.

The screen has four tabs: Overview, Operations, Settings, and History.

Open the Device detail screen

Sign in and pair a device

If you have not paired any printers yet, the Devices tab shows an empty state. Pair one through Pairing or Manual connect first.

Tap the Devices tab

The bottom navigation bar opens the list of all printers paired at your active location.

Tap a device tile

This opens the Device detail screen for that printer. Use the back arrow in the top-left to return to the list.

Read the header

The header shows three things at a glance:

  • The device name.
  • A status badge next to the name — Online, Connecting, Disconnected, or Error.
  • A subtitle with the protocol, transport, and location, for example Datecs · Bluetooth · Main Store.

The four tab pills sit just below the header. Tap any pill to switch tabs.

Switching tabs reloads that tab's content. If you opened a form on one tab and switch away, your unsaved input is lost. The Overview cash balance is also re-fetched each time you return to that tab.

Check the printer in Overview

The Overview tab shows three cards.

Device info

A grid of read-only details about the printer:

LabelWhat it shows
ProtocolThe fiscal protocol family (for example Datecs, Tremol, Custom).
TransportHow the app talks to the printer — Bluetooth, Serial, USB, or TCP.
ConnectionThe address — host:port for TCP, otherwise the device address.
ControllerThe assigned controller, or Unassigned.
LocationThe store this printer belongs to.
Last seenWhen the app last reached the printer (e.g. 5m ago, yesterday).

Cash balance

This card reads the current cash drawer balance directly from the printer:

  • If the printer is offline, the card shows a placeholder and skips the read.
  • While the read is in flight, you see a spinner.
  • If the printer rejects the read, you see the error message.
  • On success, the amount appears formatted in Romanian style with the currency code (for example 1.234,56 RON).
The cash balance is read once when you open the tab. It does not refresh on its own. If you make a cash deposit or withdrawal, switch to another tab and back to Overview to see the updated amount.

Alerts

Shows No active alerts when everything is fine. Serious connection problems surface through the status badge in the header instead.

Run fiscal operations

The Operations tab groups every printer command into five collapsible sections. All sections are expanded by default — tap a section header to collapse it.

If the printer is offline, every action button is disabled and a banner at the top of the tab tells you why.

Manage cash

  • Cash deposit — record cash added to the drawer. Opens a form to enter the amount.
  • Cash withdrawal — record cash removed from the drawer. Opens a form to enter the amount.

Configure the printer

  • Sync date and time — push the phone's current date and time to the printer.
  • Set VAT rates — review and update the printer's VAT rates. Opens a form prefilled with the current values.
  • Set header and footer — edit the lines printed at the top and bottom of every receipt.
  • Set operator — assign the operator code that will appear on receipts.
  • Print duplicate — reprint the last issued receipt.

Run reports

  • X report — print a non-resetting daily summary. Safe to run any time.
  • Z report — close the fiscal day. This is irreversible. The app asks you to confirm before sending the command.

Use advanced tools

  • Open drawer — pop the cash drawer connected to the printer.
  • Upload logo — send a logo bitmap to be printed on receipts.
  • Delete logo — remove the logo bitmap from the printer. The app asks you to confirm.
Each button shows a spinner while the command runs and is disabled until it finishes, so you cannot accidentally send the same command twice.

Each command is logged automatically. Switch to the History tab to see every command sent from this device, along with whether it succeeded.

Manage device settings

The Settings tab has three cards.

Rename the device

Change the printer's name in the text field and tap Save. The new name appears in the header and on the Devices list immediately.

Review the connection

A read-only summary of the protocol, transport, and connection address. To change any of these, remove the device and pair it again.

Remove the device

Tap Remove device to unpair the printer. The app asks you to confirm. After removal, you return to the Devices list. To use the printer again, pair it through Pairing or Manual connect.

Fiscal settings — VAT rates, header and footer, operator code — live on the Operations tab under Configure the printer, not here. The Settings tab is only for renaming the device, viewing connection info, and removing it.

View command history

The History tab lists every command sent to this printer, newest first.

Each row shows:

  • The command type (for example X report, Cash deposit, Set VAT).
  • A status pill — green for success, red for error.
  • A relative timestamp (e.g. Just now, 5m ago, 3d ago).

When the list is empty, you see a placeholder explaining no commands have been sent yet.

The history is read-only inside the app. For receipt-level audit across all devices, use Receipts in the portal.

Handle a missing device

If the device you opened was removed — by you, by another operator, or by an admin in the portal — the screen shows a Device not found message and a Back button.

This usually happens when:

  • You removed the device on the Settings tab and tried to return through a back button or notification.
  • An admin unpaired the device from the portal while the screen was open.
  • You switched the active location and the device no longer belongs to it.
Support tip: if a customer reports their device "disappeared", ask them to (1) check the Devices tab, (2) sign out and back in to refresh from the cloud, and (3) re-pair through Pairing if it still does not appear.

Where to next

  • Devices — the list that opens this screen.
  • Daily operations — issue receipts (separate from per-device fiscal operations).
  • Settings — app-wide settings such as account, language, and active location.
  • Portal → Devices — manage the same fleet from a desktop browser.
