📖 About This Skill

name: broder-printer description: Brother DCP-T426W network printer skill — IPP + driverless (primary), TCP direct (fallback for text-only, no sudo). version: 5.0.0

Brother DCP-T426W Printer Skill

When to Use

  • When you need to print text, images, or PDFs to a Brother DCP-T426W from a CLI or script
  • When you're on a NAS, Linux, or macOS machine with CUPS and want driverless IPP printing
  • When you need a text-only fallback on a headless or no-root system (TCP direct, no CUPS)
  • When you want to check printer status or print a test page programmatically

    • How It Works

    Printing to a Brother DCP-T426W inkjet printer via two methods:

    1. IPP + driverless PPD (primary) — Full support: text, images, PDFs. Requires CUPS with driverless. 2. TCP direct (fallback) — Text only, no CUPS, no sudo required.

    Supported platforms: Any device with CUPS + driverless (NAS, Linux, macOS) or Python 3 with TCP access (fallback).

    Printer Info

    | Field | Value | |-------|-------| | Model | Brother DCP-T426W | | IP | 192.168.50.232 | | Protocol | IPP (ipp://192.168.50.232:631/ipp/print) — primary; TCP 9100 fallback | | Type | Color Inkjet MFP (Print / Scan / Copy) | | Max Resolution | 4800 x 1200 dpi | | Paper | A4, Letter, A5, A6, Photo (10x15cm), Envelopes |

    Quick Start

    # Print a text string (CUPS IPP)
python scripts/print.py --text "Hello World"
    Print a file (text, image, PDF — CUPS handles conversion)
    
python scripts/print.py --file document.txt
python scripts/print.py --file photo.jpg
python scripts/print.py --file report.pdf
    Print a receipt-style text
    
python scripts/print.py --text "Invoice #123\nTotal: $42.00" --mode receipt
    Print a test page
    
python scripts/print.py --test
    Check printer status
    
python scripts/print.py --status
    Fallback: TCP direct (text only, no CUPS needed)
    
python scripts/print.py --text "Hello" --method tcp

    Setup (One-Time)

    Step 1: Install CUPS + driverless

    # Linux (Debian/Ubuntu)
sudo apt install cups cups-filters ipp-usb
sudo systemctl enable --now cups
    macOS — CUPS is built-in, skip this step

    Step 2: Generate driverless PPD and add printer

    # Generate PPD from printer's IPP capabilities
driverless "ipp://192.168.50.232:631/ipp/print" > ~/brother.ppd
    Add printer to CUPS
    
sudo lpadmin -p Brother_DCP-T426W \
  -v "ipp://192.168.50.232:631/ipp/print" \
  -E \
  -P ~/brother.ppd
    sudo lpadmin -p Brother_DCP-T426W -o printer-is-shared=false
    Verify
    
lpstat -p Brother_DCP-T426W -l

    Step 3: Test

    echo "Hello" | lp -d Brother_DCP-T426W

    How It Works

    IPP + driverless (default): 1. Script calls CUPS lp command 2. CUPS converts input (text/image/PDF) to PWG-raster using the driverless PPD 3. Data sent to printer via IPP protocol 4. Printer renders and prints

    TCP direct (fallback, --method tcp): 1. Script opens TCP socket to printer port 9100 2. Wraps text in PJL (Printer Job Language) commands 3. Sends data directly to printer 4. Text only — images/PDFs need CUPS conversion

    IPP vs TCP

    | Feature | IPP + driverless | TCP Direct | |---------|-----------------|------------| | Setup | CUPS + driverless | None | | sudo required | Setup only (once) | No | | Text printing | Yes | Yes | | Image printing | Yes (PWG-raster) | No (raw bytes only) | | PDF printing | Yes | No | | Print queue | Yes | No | | Use case | NAS, desktop, full features | Headless, no-root, text-only |

    Direct CUPS Commands

    # Print any file CUPS understands
lp -d Brother_DCP-T426W file.txt
    Print with options
    
lp -d Brother_DCP-T426W -o media=A4 -o sides=one-sided document.pdf
    Check jobs
    
lpstat -o Brother_DCP-T426W
    Cancel jobs
    
cancel Brother_DCP-T426W

    Troubleshooting

    | Issue | Solution | |-------|----------| | driverless: command not found | sudo apt install cups-filters ipp-usb | | IPP connection refused | Verify printer supports IPP: driverless (list available IPP printers) | | No paper output | Check paper tray, ink levels, printer not in error state | | TCP prints garbled text | Printer may not support PJL PLAINTEXT — use IPP method | | CUPS printer not found | lpstat -p to list printers; re-run lpadmin setup | | lp command not found | sudo apt install cups-client |
