Multifunction Devices
On this page

In one line: an MFD (printer/scanner/fax) needs a model- and bitness-matched driver, a page language (PCL or PostScript), a connection (USB/Ethernet/Wi-Fi), and — for shared use — a print server, secure release, and scan-to destinations.

Companion to: Professor Messer A+ Core 1 (220-1201), Section 3, objective 3.7. The full version is the Multifunction Devices class notes; the section overview is the Section 3 sheet.

Setup and drivers

Step Detail
Place Power + (usually) wired network; accessible, out of the walkway
Driver Model-specific, matching OS and bit-width (32→32, 64→64); unlocks full features
PDL PCL (Printer Command Language, HP) or PostScript (Adobe) — driver must match
Firmware Device OS; update from the vendor site, follow their process (every device differs)

Connectivity

Type Notes
USB Type A at PC; Type B / USB-C at printer
Ethernet RJ45 (can run alongside USB simultaneously)
Bluetooth Short range — be close
802.11 infrastructure Via an access point (shared)
802.11 ad hoc Point-to-point, no AP (modern equivalent: Wi-Fi Direct)

Sharing

  • OS sharing: printer properties → Sharing tab → network name. Downside: host PC off = nobody prints.
  • Print server (in the printer or external): queues/manages jobs, web front end, add/remove from queue.
Feature Options
Duplex Both sides (may need extra hardware)
Orientation Portrait / landscape (page doesn’t physically turn)
Trays Multiple types/sizes; a default (e.g. Tray 1 = Letter)
Quality Resolution (e.g. 600×600 dpi), colour/grayscale, colour/toner-saving

Secure output

Control What it does
Auth / permissions Limit who can print vs manage (users/groups)
Badging Job held until you badge in at the printer
Secured print Job held until you enter a PIN/passcode (Windows PIN printing)
Auditing Who printed how much — device log or Windows Event Viewer

Scanning

  • Flatbed; ADF = Automatic Document Feeder for multi-page.
  • Scan to: email (small jobs) · folder / SMB (Server Message Block, Windows share; large jobs; SMB = TCP 445) · cloud (Google Drive, Dropbox).

🔐 Security notes

  • An MFD is a networked computer: firmware OS, web admin, internal storage — patch it, change default admin passwords, disable unused services (incl. fax line), and put it on a segmented VLAN.
  • Scan-to holds credentials: SMB share creds, SMTP, cloud tokens live on the device — use a least-privilege account for scan-to-folder, never domain admin.
  • Physical output leaks: badging / PIN secured print keep sensitive documents out of the tray; audit logs record misuse.
  • Internal drives cache documents: wipe/remove the drive before disposal.
  • Print path is attack surface: Print Spooler (PrintNightmare) and kernel-level printer drivers — patch, restrict driver install, vendor drivers only.

Practice drills

1. Three things a printer driver must match?

The model, the OS, and the OS bit-width (32-bit OS → 32-bit driver, 64-bit → 64-bit).

2. Name the two page description languages and their creators.

PCL (Printer Command Language) by HP, and PostScript by Adobe.

3. Infrastructure vs ad hoc 802.11?

Infrastructure connects via an access point (shared); ad hoc is a direct point-to-point link with no AP.

4. Weakness of sharing a printer directly from a PC, and the fix?

If that PC is off, nobody can print — use a print server instead.

5. Badging vs secured print?

Both hold the job until you’re at the printer; badging releases with a badge, a secured print with a PIN/passcode.

6. Three scan-to destinations, and when folder beats email?

Email, folder/SMB share, and cloud; scan-to-folder suits large jobs that would overwhelm an inbox.

7. Why is a decommissioned MFD a data risk?

Its internal drive may cache scanned/printed documents — wipe or remove it before disposal.

Key takeaways

  • Driver = model + OS + bit-width; match the PDL (PCL/PostScript); update firmware from the vendor.
  • Connect via USB (A→B/C), RJ45, Bluetooth, or 802.11 infrastructure/ad hoc.
  • Print server beats direct sharing (no dependence on one PC).
  • Features: duplex, portrait/landscape, trays, quality; secure output via auth, badging, PIN secured print, auditing.
  • Scan (flatbed/ADF) to email, SMB folder, or cloud — and treat the MFD as a networked computer to patch, segment and wipe.
