HTML5 and Remote Desktop access have different printer handling mechanisms – make sure that you are using the correct one:
To enable a printer in RDP, you must enable it in your local remote desktop. Check with your local IT team to make sure it is visible, along with any local drives and other equipment you need to use.
HTML5 clients will need to use a native client like RemoteApp in order to bridge the gap between the browser and local hardware. This is a necessary step to ensure optimal security – otherwise, every website you visit could theoretically access your local drives, printers, scanners, and other equipment.
