Lexmark’s monochrome office printers—notably the Lexmark MS310d, MS310dn, MS410, E260d, and E360d—are renowned for their industrial build quality, high-speed 35 to 40 ppm paper delivery, and rapid first-page-out times under 6.5 seconds. Powered by Lexmark’s specialized Unison Toner and high-yield cartridges (such as the 50F1000 / 50F1H00 and E260A11A), these printers routinely outlive modern budget plastic alternatives.

Most of these desktop workhorses feature built-in hardware automatic two-sided printing (d models) and heavy-duty 850-sheet expandable paper feeders.

However, getting an iPhone, iPad, or Android phone to print to a USB-connected Lexmark printer is notoriously difficult:

AirPrint Hardware Paywall: Base USB models (like the MS310d or E260d) lack network connectivity. To get official wireless printing, Lexmark required customers to purchase an expensive MarkNet N8352 wireless card or external print server costing upwards of $150.
Lexmark Mobile Print App Limitations: Lexmark’s mobile app relies on Bonjour broadcast discovery to discover networked multi-function devices. It has zero capability to see USB-connected desktop printers.
Complex Universal Print Drivers: Lexmark printers thrive on PostScript 3 and PCL 6 emulation. Inexpensive USB wireless dongles cannot properly translate modern mobile PDF print jobs into Lexmark PostScript/PCL streams without garbled text or missing fonts.

With Printman, you don’t need to spend $150 on hardware adapters. By turning your Windows PC into a local LAN printing gateway, Printman gives you full mobile wireless printing to your Lexmark laser printer in minutes.

Why Buy a Lexmark MarkNet Adapter When You Have Printman?

Lexmark manufactured optional wireless print server cards (the MarkNet series) for its enterprise lineup. Comparing that legacy hardware upgrade to Printman highlights why a software bridge is the smarter approach:

Step 1: Ensure Your Lexmark Printer is Configured on Windows

Printman interfaces directly with the official Lexmark Universal Print Driver (UPD), ensuring complete fidelity for graphics, complex tables, and duplexing:

Connect your Lexmark printer to your Windows PC with a high-speed USB-A to USB-B cable.
Download the Lexmark Universal Print Driver (PCL 6 or PostScript 3) from Lexmark’s official support website.
Open Windows Settings > Bluetooth & devices > Printers & scanners.
Click on your Lexmark printer and open Printer properties > Device Settings:
- Set Duplex to Installed (if using MS310d, MS410d, or E260d).
- Confirm paper trays (Tray 1: 250 sheets, Tray 2: optional 550 sheets) match your physical setup.
Print a Windows test page to confirm the USB link is functional.

Step 2: Download and Launch the Printman Server

Printman is packaged as a single portable, zero-dependency binary that does not modify your system registry or install hidden background telemetry.

Download the standalone ZIP package (printman-win-x64-standalone.zip) from the Printman GitHub Releases.
Extract printman.exe to a permanent folder, for instance C:\Tools\Printman.
Open PowerShell or Command Prompt in that directory and start the server:

./printman.exe serve --no-auth

Security Note: In an office or shared building environment, run ./printman.exe serve --pin 310360 to enforce PIN authentication for all mobile print requests.

Printman initializes its embedded Kestrel web server and outputs your local network URL:

  [WEB SERVER RUNNING]  Port: 5000
  [SECURITY] Open Access (No PIN required)

  Access from this machine or your phone on the same Wi-Fi:
    Local:    http://localhost:5000/
    Network:  http://192.168.1.192:5000/

Step 3: Print Directly from Safari or Chrome on Your Phone

With Printman active, any mobile device on your local Wi-Fi network can print without installing drivers:

Ensure your smartphone or tablet is connected to the same home or office Wi-Fi.
Open mobile Safari (iOS) or Chrome (Android) and navigate to the Network URL (e.g., http://192.168.1.192:5000).
In Printman’s clean, mobile-first interface:
- Tap Select Documents to upload invoices, shipping labels, contracts, or photos.
- In the printer dropdown, choose your Lexmark MS310 / E260 series printer.
- Select your Duplex setting (Long Edge for standard double-sided documents).
- Configure paper size (Letter or A4) and page selection.
Tap Print.

Printman immediately ingests the file, rasterizes the vector payload at 300 DPI, and routes it through the Lexmark Universal Print Driver. Your Lexmark printer will initiate its instant fuser and finish printing your job in seconds.

Pro Tip: Run Printman as an Always-On Windows Service

To ensure your Lexmark printer remains accessible 24/7 without needing an interactive user session:

Open PowerShell as Administrator and run the following command to register a startup task:

$action = New-ScheduledTaskAction -Execute "C:\Tools\Printman\printman.exe" -Argument "serve --no-auth"
$trigger = New-ScheduledTaskTrigger -AtStartup
$principal = New-ScheduledTaskPrincipal -UserId "SYSTEM" -LogonType ServiceAccount -RunLevel Highest
Register-ScheduledTask -TaskName "PrintmanLexmarkService" -Action $action -Trigger $trigger -Principal $principal

Once registered, Printman automatically launches as soon as your Windows machine powers on, turning your USB Lexmark workhorse into a permanent wireless print station.

Frequently Asked Questions (FAQ)

Can I print double-sided (duplex) pages from my iPhone to the Lexmark MS310d?

Yes! The d in Lexmark model names (MS310d, MS410dn, E260d, E360d) indicates an integrated automatic duplexing unit. Printman automatically queries the Windows driver for hardware duplexing capabilities. In the mobile web UI, simply select Duplex: Long Edge (or Short Edge for flip-over booklets), and the printer will feed the sheet back in to print both sides automatically.

What is Lexmark Unison Toner and why does it matter?

Lexmark’s proprietary Unison Toner features a unique formulation that reduces friction inside the cartridge. This minimizes internal wear on mechanical components, provides consistent dark monochrome text throughout the cartridge’s life, and requires lower fusing temperatures, saving electricity and speeding up print wake-up times.

Why doesn’t the Lexmark Mobile Print app work with my USB printer?

The official Lexmark Mobile Print app relies strictly on network discovery protocols (SNMP, mDNS, and Bonjour) to locate network-attached printers on the same subnet. Because USB printers have no network interface of their own, the mobile app cannot communicate with them. Printman bridges this gap by letting your Windows PC act as the network-accessible gateway.

Can I print from Android devices without installing Google Cloud Print?

Yes. Google Cloud Print was officially deprecated and shut down in 2020. Printman provides an entirely local, zero-cloud alternative that runs inside Android’s Google Chrome or any other mobile browser. No cloud relays, third-party apps, or Google accounts are required.
