Bulk Printing QR Codes in PRTG

PRTG offers a hidden feature which allows you to display QR codes of all devices at glance. You can call a corresponding page suitable for printing by adding certain parameters to the URL of your PRTG installation. It is also possible to call a page showing only QR codes of devices within a specific group or probe. In addition, the size of the QR codes on this page is adjustable to your needs.

Important notice: Please note that this is a hidden feature. We cannot guarantee that it will be forever working the way as denoted below.

Calling a Page with Printable QR Codes

Log in to your PRTG installation. Add parameters to the IP address/DNS name of your PRTG server as pointed out below.

• In order to call a page containing the QR codes of all devices on your PRTG installation, add devices-qr.htm to the URL: https://yourprtgserver/devices-qr.htm

• In order to show only QR codes of devices within a specific group or probe, add the corresponding ID to the URL: https://yourprtgserver/devices-qr.htm?id=group_or_probe

• Alternatively, you can go to a device list via the main menu (choose Devices | Device List >) and simply add -qr between devices and .htm in the current URL. This is also possible when you are on the Favorite Devices page: https://yourprtgserver/devices-qr.htm?filter_favorite=1

• You can adjust the size of the displayed QR codes by providing according parameters for width, height, and margin. The following units are possible:

Parameter in URL	Unit
in	inch
cm	centimeter
mm	millimeter
em	1em is equal to the current font size. 2em means two times the size of the current font. E.g., if an element is displayed with a font of 12 pt, then '2em' is 24 pt. The 'em' is a very useful unit in CSS, since it can adapt automatically to the font that the reader uses
ex	one ex is the x-height of a font (x-height is usually about half the font-size)
pt	point (1 pt is the same as 1/72 inch)
pc	pica (1 pc is the same as 12 points)
px	pixels

• Add the desired units as parameters to the URL, connected with ampersands. For example: https://yourprtgserver/devices-qr.htm?id=group_or_probe&width=150px&height=150px&margin=50px
