Printer Technology Guide

Everything you need to know before choosing a printer. Understand toner systems, RAM, scanning, duplex, finishers, software, and security to make the right decision for your office.

Toner & Ink Systems

The consumable that determines your cost per page

How Laser Printing Works

1

Charge

The OPC drum is given a uniform electrical charge by the primary charge roller

2

Expose

A laser beam writes the image onto the drum, discharging areas where toner should stick

3

Develop

Toner powder is attracted to the discharged areas of the drum, forming the image

4

Transfer

The toner image is transferred from the drum onto the paper via the transfer belt

5

Fuse

Heat and pressure from the fuser unit permanently bond the toner to the paper

Colour laser printers repeat steps 1-4 four times — once for each colour: Cyan (C), Magenta (M), Yellow (Y), and Black (K). The four toner layers are combined on the transfer belt before fusing.

Conventional vs Polymerised Toner

Conventional (Pulverised) Toner

Made by crushing and grinding raw materials. Particles are irregular in shape and size (6-10 microns). Used in most standard printers. Lower manufacturing cost.

Polymerised (Chemical) Toner

Chemically grown into uniform, spherical particles (5-7 microns). More consistent coverage, sharper detail, lower fusing temperature = less energy. Used by Konica Minolta (Simitri HD), Canon (V2 toner), and Ricoh (PxP-EQ).

Bottom line: Polymerised toner gives better print quality and uses less energy, but the printer may cost more upfront.

Cartridge vs Drum: What's the Difference?

Integrated Cartridge (Toner + Drum)

The toner and imaging drum are combined in one unit. When you replace the toner, you also get a fresh drum. Simpler to replace but higher per-page cost. Used by HP and some Canon models.

Separate Toner & Drum

The toner cartridge and drum unit are independent. You replace the toner frequently but the drum lasts 3-5x longer. Lower running cost overall. Used by Brother (TN/DR series), Kyocera (drum lasts the printer's lifetime), Konica Minolta, and Ricoh.

Kyocera's ECOSYS: The drum is rated for the entire life of the printer (up to 300,000+ pages), so you only ever replace the toner — lowest TCO in the industry.

Toner Yield & Cost Per Page

How Yield is Measured

Toner yield is measured by the ISO/IEC 19752 (mono) and ISO/IEC 19798 (colour) standards. These use a standardised test page with 5% coverage — roughly a half page of text. Real-world documents with photos, charts, or heavy text will use more toner per page.

Typical Yields
Standard Mono Cartridge3,000 - 6,000 pages
High-Yield Mono Cartridge10,000 - 25,000 pages
Standard Colour Set (CMYK)2,000 - 5,000 pages each
High-Yield Colour Set6,000 - 12,000 pages each

Calculating Cost Per Page

Cost per page = Toner price ÷ Rated yield

For colour: add all four cartridge costs (C+M+Y+K) then divide by yield

Typical Cost Per Page (HK Market)
Desktop Mono LaserHK$0.10 - $0.15
Enterprise Mono LaserHK$0.04 - $0.08
Desktop Colour LaserHK$0.60 - $1.00
A3 Colour MFPHK$0.30 - $0.50
Ink Tank (e.g. Canon G6070)HK$0.02 - $0.04

Inkjet: Ink Tank vs Cartridge

Traditional Ink Cartridge

  • Small ink volume (5-15 ml per cartridge)
  • High cost per page (HK$0.50-2.00 colour)
  • Frequent replacement
  • Lower printer purchase price

Ink Tank / MegaTank / EcoTank

  • Large refillable tanks (70-140 ml per colour)
  • Extremely low cost per page (HK$0.02-0.04)
  • One refill prints 6,000-8,000+ pages
  • Canon MegaTank, Epson EcoTank, Brother InkBenefit

RAM & Storage (Hard Disk / SSD)

Why printers need processing power

RAM (Memory)

RAM processes and holds print jobs before they reach the imaging engine. More RAM = faster processing of complex documents (graphics, large PDFs, multi-page jobs).

256 MB Basic desktop printers (text documents)
512 MB - 1 GB Mid-range printers & small office MFPs
2 - 4 GB Enterprise MFPs (large jobs, multiple users)
8 GB+ Production presses & heavy workgroup

The Konica Minolta bizhub C360i ships with 8 GB RAM — more than many laptops — enabling fast processing of complex colour documents for large workgroups.

Storage (HDD / SSD)

Built-in storage enables advanced features beyond basic printing. Here is what the hard disk or SSD actually does:

Secure Print (Hold & Release)

Jobs are stored on the SSD and only printed when you enter a PIN at the machine. Prevents confidential documents sitting in the output tray.

Document Mailbox

Frequently-used forms, templates, and documents stored on the printer for instant re-printing without a PC.

Job Spooling

Large print jobs (100+ page booklets) are spooled to disk so your computer is freed up immediately.

Scan Storage

Scanned documents can be saved to the built-in storage for later retrieval, forwarding, or OCR processing.

Security note: When decommissioning a printer, the SSD/HDD should be securely erased. Most enterprise printers have a built-in "Data Overwrite" function that writes random data to the disk. Canon, Ricoh, and Konica Minolta all offer this.

Duplex (Double-Sided) Printing

Save paper, cut costs, look professional

1

No Duplex (Simplex Only)

Prints on one side only. You must manually flip sheets to print the other side. Rarely seen on modern office printers but common on basic models.

M

Manual Duplex

The printer prompts you to flip the paper stack and reinsert it into the tray. Works but slows you down and can cause paper jams if sheets aren't aligned properly.

A

Auto Duplex (Recommended)

The printer automatically flips the page internally and prints the second side. No user intervention needed. Standard on all modern business printers.

All 21 printers we sell include auto duplex as standard.

Duplex Printing: What to Know

  • 1Speed reduction: Duplex printing is typically 40-60% of simplex speed because the paper must travel through the engine twice. A 60 ppm printer may print ~30-36 ppm in duplex.
  • 2Paper weight limits: Most auto duplex units handle 60-163 gsm. Heavier card stock (200+ gsm) may be too stiff to flip automatically — you will need to print it manually.
  • 3Paper savings: Duplex printing halves your paper consumption. A 10,000-page/month office saves ~HK$200-400/month in paper alone.
  • 4Duplex scanning: Different from duplex printing. See the Scanning section for single-pass vs reversing ADF.
  • 5Default setting: IT departments often set duplex as the default in the print driver to reduce paper usage company-wide.
  • 6Booklet printing: Combined with a booklet finisher, duplex enables automatic creation of saddle-stitched booklets (folded and stapled in the centre).

Scanning & Document Feeder

Convert paper to digital — the modern office essential

ADF (Auto Document Feeder)

Feeds documents through the scanner one side at a time. For duplex scanning, the page is fed through once, flipped, and fed through again.

Speed: Moderate (simplex only or slow duplex)

Capacity: 50-100 sheets

Found on: Desktop MFPs, entry-level devices

RADF (Reversing ADF)

Scans one side, reverses the page through the same scanner to scan the other side. Faster than flipping manually but still two passes per sheet.

Speed: 2x simplex speed for duplex

Capacity: 50-100 sheets

Found on: Mid-range MFPs

SPDF (Single-Pass Duplex Feeder)

Two scan heads scan both sides of the page simultaneously in a single pass. The fastest method — duplex scanning at full simplex speed.

Speed: Up to 300 ipm (Ricoh IM C6010/C3010)

Capacity: 100-300 sheets

Found on: Enterprise A3 MFPs (all our A3 models)

Scan Speed Explained

Scan speed is measured in ipm (images per minute). In duplex mode, each sheet produces 2 images, so a 300 ipm duplex scanner processes 150 sheets per minute.

ModelDuplex ipm
Ricoh IM C6010 / C3010300 ipm
Canon DX C5860i270 ipm
Konica bizhub C360i / C250i200 ipm
Canon DX C3830i270 ipm
HP M428fdw (desktop)49 ipm

Scan Destinations

Modern MFPs can send scanned documents to multiple destinations:

@
Scan to Email

Scanned PDF/JPEG sent directly as email attachment via SMTP

F
Scan to Folder (SMB/FTP)

Files saved directly to a shared network folder or FTP server

U
Scan to USB

Save directly to a USB drive inserted in the printer

C
Scan to Cloud

Direct integration with Google Drive, OneDrive, Dropbox, Box

OCR
Searchable PDF (OCR)

Built-in OCR converts scanned images to searchable text. Essential for document archiving.

Scan Resolution: When Does It Matter?

200 dpi

Standard text documents, emails, and basic filing. Fast scan speed. Good enough for most office use.

300 dpi

The sweet spot for text + images. Recommended for contracts, receipts, invoices, and documents with fine print or logos.

600 dpi

High detail for photos, architectural drawings, and OCR of tiny text. Much slower scan speed and larger file sizes.

Paper Handling & Capacity

How much paper, what sizes, and how heavy

Paper Cassettes

Enclosed drawers that hold 250-550 sheets each. Protected from dust. Most printers come with 1-2 cassettes standard and can add more (up to 4-5 total).

Example: Canon C5860i — standard 1,200 sheets, max 6,350 with additional cassettes.

Multi-Purpose (Bypass) Tray

An open tray for special media: envelopes, labels, card stock, transparency film, and heavy paper. Usually holds 50-100 sheets. Feed one type of media without changing the main cassette.

Supports wider weight range than cassettes (up to 300 gsm on some models).

Large Capacity Tray (LCT)

An optional high-volume tray (1,500-4,000 sheets) for offices with heavy print volumes. Reduces the frequency of paper refills. Usually holds A4/Letter only.

Essential for busy offices printing 10,000+ pages/month.

Paper Weight Guide (GSM)

GSM (grams per square metre) measures paper thickness and stiffness. Different printer components handle different weight ranges.

Weight (GSM) Common Name Typical Use Auto Duplex?
60 - 80 gsmStandard office paperEveryday printing, internal docs
80 - 105 gsmPremium paper / letterheadClient letters, proposals
105 - 163 gsmLight card / coverFlyers, menu inserts, covers
163 - 220 gsmCard stockBusiness cards, postcards, invitationsSome models
220 - 300 gsmHeavy cardBox inserts, thick covers
300 - 400 gsmBoardProduction presses only (Xerox V280, Ricoh C5310s)

Finishers: Stapling, Booklet & Folding

Automate post-print tasks directly at the printer

Inner Finisher

Built into the printer body. Offers basic stapling (corner or dual-point) and sorting. Compact, no extra space needed. Handles up to 50 sheets per set.

Best for: Small offices with basic stapling needs

External Staple Finisher

Attaches to the side of the printer. Supports corner staple, dual staple, and offset sorting. Higher capacity output bins (up to 3,000+ sheets). Available with optional hole punch.

Best for: Medium offices needing reliable stapling

Booklet Finisher

The most advanced option. Includes saddle-stitch stapling (2 staples in the centre fold), automatic folding to create booklets, and sometimes trimming for clean edges.

Best for: Marketing departments, print rooms, production

Hole Punch Unit

Integrated into the finisher. Automatically punches 2 or 4 holes for ring binder filing. Choose 2-hole (international) or 4-hole (European/Japanese) depending on your binders.

Common option on Canon, Ricoh, Konica MFPs

Folding Unit

Folds output automatically. Common fold types: C-fold (letter fold for envelopes), Z-fold (accordion fold for A3 drawings in A4 binders), and half-fold (bi-fold).

Essential for: Engineering offices (Z-fold A3 plans)

Stapleless Binding

Ricoh's eco-friendly option: binds up to 5 sheets together by pressing and interlocking the paper fibres — no metal staples needed. Ideal for internal documents.

Exclusive to: Ricoh IM C series MFPs

Software & Print Drivers

The invisible layer that makes printing work

Print Drivers & Languages

PCL 6 (PCL XL)

HP's Printer Command Language. The standard for office printing. Fast processing, good text quality, wide compatibility. Used by virtually every business printer.

PostScript 3 (PS3)

Adobe's page description language. Essential for graphic design, DTP, and accurate colour reproduction. Required for Adobe Creative Suite workflows. Slightly slower than PCL for plain text.

PDF Direct Print

Send PDF files directly to the printer without opening them in an application. The printer's built-in PDF engine renders the file. Convenient for batch printing.

Mobile Printing

Apple AirPrint

Built into iOS/macOS. Print from any Apple device on the same WiFi network. No driver installation. Supported by all major brands.

Mopria Print Service

The Android equivalent of AirPrint. Built into Android 8+. Automatic printer discovery on the network.

Wi-Fi Direct

Print directly from a phone/laptop to the printer without a WiFi router. Peer-to-peer connection. Useful for guest printing.

NFC Tap-to-Print

Tap your phone on the printer's NFC reader to connect instantly. Available on Brother and Konica Minolta models with NFC.

Fleet Management Software

For offices with multiple printers, fleet management software provides centralised control:

HP Web Jetadmin

Discover, configure, and monitor all HP printers from one console. Set default driver settings, push firmware updates, view toner levels.

Ricoh @Remote

Automatic toner reordering, meter reading, and service alerts sent to your dealer. The printer calls for help before you notice a problem.

Canon imageWARE / uniFLOW

Enterprise print management with secure pull printing, cost tracking per user/department, and mobile release. uniFLOW Online is cloud-based.

Kyocera Fleet Services

Cloud-based fleet monitoring, automated supply ordering, and proactive maintenance alerts for Kyocera devices.

Pull Printing / Follow-Me Printing

1

Print

Send your document to the "Pull Print" queue from your PC — it doesn't print yet

2

Walk

Walk to any printer in the office or building

3

Authenticate

Tap your IC card, enter a PIN, or scan your face at the printer

4

Release

Your document prints right there — secure, private, no waste

Pull printing eliminates uncollected prints (studies show 20% of printed pages are never picked up), protects confidential documents, and lets users print from any device to any printer. Implemented via Canon uniFLOW, Ricoh Streamline NX, Konica Minolta Dispatcher Phoenix, or third-party solutions like PaperCut and YSoft SafeQ.

Network & Connectivity

How your devices talk to the printer

Ethernet (Wired LAN)

The most reliable connection. Gigabit Ethernet (1000Base-T) is standard on all enterprise printers. Recommended for office environments — stable, fast, secure.

Recommended for all offices

WiFi (Wireless LAN)

802.11 b/g/n/ac for flexible placement. Dual-band (2.4 + 5 GHz) on newer models. Convenient but can be slower and less reliable than wired for high-volume printing.

Standard on desktop, optional on many A3 MFPs

USB

USB 2.0 for direct PC connection (1 PC at a time). USB Host port on the front lets you print from or scan to a USB flash drive. USB 3.0 on some wide format models.

Always available as backup

NFC & Bluetooth

NFC for tap-to-connect pairing with mobile devices. Bluetooth Low Energy (BLE) for proximity detection and quick setup. Available on Konica bizhub, Brother, and select Canon/Ricoh.

Convenient for mobile workers and guests

Security Features

Printers are network endpoints — protect them accordingly

Why printer security matters: Modern MFPs are essentially computers on your network. They store documents on internal drives, connect to email servers, hold user credentials, and can be accessed remotely. An unsecured printer is a potential entry point for attackers and a data leak risk.

Hardware Security

Secure Boot / Verified Startup

The printer checks its firmware integrity on every boot. If tampering is detected, it halts or restores from a trusted backup. Canon calls this "Verify System at Startup"; HP calls it "Sure Start".

Runtime Intrusion Detection

HP Wolf Security continuously monitors the printer's memory during operation for malicious code injection. Automatically reboots and self-heals if an anomaly is detected.

Firmware Whitelisting

Only digitally-signed firmware from the manufacturer can run on the device. Prevents installation of modified firmware. Standard on HP Enterprise and Canon ADVANCE DX.

Built-in Anti-Virus

Konica Minolta bizhub i-Series includes a built-in Bitdefender anti-virus engine that scans documents and USB drives for malware in real-time.

Data Security

Encryption at Rest (SSD/HDD)

All data on the printer's internal storage is encrypted with AES-256. Even if the hard drive is physically stolen, the data cannot be read. Standard on all enterprise MFPs.

Encryption in Transit (TLS/IPsec)

Print jobs, scan data, and admin traffic are encrypted between your PC and the printer using TLS 1.3 or IPsec. Prevents network eavesdropping.

Data Overwrite (Sanitisation)

After every job, the printer can automatically overwrite the SSD areas used for that job with random data (DoD 5220.22-M standard). Ensures no residual data remains. Essential before decommissioning.

User Authentication

Restrict who can print, copy, and scan. Methods: PIN code, IC card (Octopus, HID), username/password, LDAP/Active Directory integration. Track usage per user or department.
