The printer does not print from Torgsoft until the Windows test page is run

When the printer stops printing after idle time

• after 15–30 minutes of POS idle time;

• after restarting the PC or waking from sleep;

• when working through RDP or a USB hub.

How to understand that the problem is specifically in the port, driver, or print queue

• the job is present in the Windows queue, but is not sent to the printer;

• Torgsoft shows no error, the receipt is “apparently sent”;

• printing starts only after Test Page in printer properties;

• the printer disappears/appears after reconnecting USB.

• the Windows queue may display the status “Delayed printing” or “Work offline”.

What most often blocks printing until the test page is launched

1. Windows power saving — the system turns off the USB port.

2. Unstable USB power — passive hubs, poor cable.

3. Print Spooler freezes — the queue is blocked.

4. Driver conflict — especially new POS printer drivers.

5. RDP redirection — the channel “falls asleep”.

6. After idle time, Windows may activate another USB port (USB00X), and the printer actually works, but not on the port selected in the printer properties.

How to restore stable printing without the Windows test page

A. Disable USB power saving (main cause)

1. Open Device Manager (devmgmt.msc).

2. Section USB controllers.

3. For each USB Root Hub / Generic USB Hub:

• Properties → Power Management.

• clear the checkbox “Allow the computer to turn off this device to save power”.

1. Control Panel → Power Options:

• High performance plan;

• USB settings → USB selective suspend setting → Disabled.

B. Check the physical connection

1. Connect the printer directly to the PC (without adapters).

2. Use USB 2.0 (black port).

3. Do not use passive USB hubs.

4. Replace the cable (length ≤ 1.8 m).

C. Restore the print service

1. Open services.msc.

2. Print Spooler (Print Spooler) → Restart.

3. Clear the print queue of the required printer. If there are frozen jobs in the queue, new documents are not sent to the printer.

4. Also check that the checkbox “Work offline” is not enabled in the print queue. If this mode is enabled, Windows does not send jobs to the printer even when the connection is active.

D. Check the driver and port

In Printer Properties → Ports, check the active port (USB001, USB002 etc.). Delete duplicate Copy 1 / Copy 2.

Make sure the checkbox is set exactly on the USB00X that corresponds to the printer’s current connection.

Path: Control Panel → Devices and Printers → right-click the printer → Printer Properties → “Ports” tab.

If another port is selected — change it, click Apply → OK.

For POS printers:

• if driver 2023–2024 is installed and there are problems — replace it with a stable version (for example, Seagull 2018.x).

E. If working through RDP

Completely end the session (Log off), not just close the window. For permanent work — configure printing via network (LPR/LPD) instead of RDP redirection. RDP redirection may “fall asleep” after idle time, while network printing works more stably.

How to check that printing has been restored

1. Leave the POS without actions for 30 minutes.

2. Create a receipt in Torgsoft.

3. Printing should start immediately, without the Windows test page.

How to avoid the problem recurring

• disable USB power saving immediately on POS PCs;

• use quality USB cables;

• do not connect POS equipment through passive hubs;

• fix stable driver versions.
