get_printer_list() -> dict

Returns a list of all available printers in the system.

2. Get Printer Status

printer_status(index: int = None) -> dict

Gets the status information of the specified printer. If no index is specified, returns the default printer status.

3. Get Printer Attributes

printer_attrs(index: int = None) -> dict

Gets detailed configuration attributes of the printer (macOS/Linux only).

4. Print File

print_file(index: int = None, file_path: str = None, options: dict = None) -> dict

Prints files using the specified printer. Supports custom print options.

Parameters:

• index: Printer index (1-based). If None, uses the default printer

🪟 Windows Options — DEVMODE Documentation

Windows uses Device Mode (DEVMODE) parameters with dm prefix:

{
    "dmCopies": 2,
    "dmOrientation": 1,
    "dmColor": 2,
    "dmPaperSize": 9,
    "dmDuplex": 1,
    "dmDefaultSource": 7,
    "dmMediaType": 0,
    "dmPrintQuality": -4,
    "dmCollate": 1
}

Option	Type	Description
dmCopies	int	Number of copies
dmOrientation	int	1 = Portrait, 2 = Landscape
dmColor	int	1 = Monochrome, 2 = Color
dmPaperSize	int	Paper size constant (1 = Letter, 5 = Legal, 8 = A3, 9 = A4, 11 = A5)
dmDuplex	int	1 = Simplex, 2 = Long Edge, 3 = Short Edge
dmDefaultSource	int	Paper source / bin
dmMediaType	int	Media type
dmPrintQuality	int	Print quality (-4 = Default, positive values = DPI)
dmCollate	int	1 = Collate, 0 = No collate

🐧🍎 Linux / macOS Options — CUPS/IPP Format

Linux and macOS use CUPS with IPP standard options:

{
    "copies": "2",
    "media": "A4",
    "orientation_requested": "3",
    "print_color_mode": "color",
    "sides": "one-sided",
    "print_quality": "4",
    "page_ranges": "1-5,10-15",
    "number_up": "1"
}

Option	Type	Description
copies	str	Number of copies
media	str	Paper size (e.g., A4, Letter, Legal)
orientation_requested	str	3 = Portrait, 4 = Landscape
print_color_mode	str	monochrome or color
sides	str	one-sided, two-sided-long-edge, two-sided-short-edge
print_quality	str	3 = Draft, 4 = Normal, 5 = High
page_ranges	str	Page ranges (e.g., 1-5,10-15)
number_up	str	Pages per sheet

API Response Format

All APIs return responses in a unified format:

{
  "code": 200,
  "msg": "success",
  "data": {
    // Specific data content
  }
}

Configuration

MCP Configuration Example

Add to your MCP configuration file:

Printer AI Skills

If you prefer a CLI + AI Skill approach instead of running an MCP server, check out printer-ai-skills. It provides a standalone printer-ai CLI tool that AI assistants (OpenClaw / Cursor / Claude) can drive directly through SKILL.md — no server process needed. Same cross-platform printing capabilities, lighter deployment.
