NX Print

NX Print provides secure access to Windows' printing infrastructure from the browser.

Use cases:

• Print PDF just-like-you-see-it to the printer (no more browser-based differences)
• Raw printer-level access (control the printer in its own language)

Features:

• Clean, modern integration. Works with all desktop browsers.
• Supports printing labels. Head over to LabelCloud offering, which is built on NX Print's technology.
