What is duplex printing, and can it help when paper cases keep disappearing from the supply closet faster than you expect? Here’s the plain answer: duplex printing is printing on both sides of a sheet of paper. Making it your default is a simple way to cut paper use on multi-page jobs. It takes a few clicks on most modern office machines, and it changes how much paper you buy, store, and throw away.
Plenty of Colorado Springs and Pueblo offices already own equipment that can print two-sided. They just never switched the setting on, or they switched it off after one bad jam and never went back.
The Difference Between One-Sided and Two-Sided Pages
A one-sided page has print on the front only. A two-sided page uses the front and the back, so one sheet holds two pages of content.
Printers and copiers use a few different names for the same idea. You’ll see “duplex printing,” “double-sided printing,” and “two-sided printing” in settings menus. The one-sided version is called “simplex printing” or “single-sided printing.”
What Is Duplex Printing Compared With Simplex Printing?
Duplex printing places page 1 on the front of a sheet and page 2 on the back. Simplex printing puts page 1 on one sheet and page 2 on a second sheet. The content stays the same. The stack gets thinner.
Here’s how each one shows up in a typical office:
- Simplex: Every page gets its own sheet. Stacks are thicker, folders fill up faster, and mailings weigh more.
- Duplex: Two pages share one sheet. Reports feel more like booklets, and binders hold more.
- Mixed jobs: Some copiers let you print a one-sided cover and two-sided pages inside, which works well for proposals.
For daily work like meeting notes, handbooks, and training packets, duplex is the practical choice. Once it becomes the default, most people stop thinking about it.
When Should a Page Stay Single-Sided?
One-sided printing still has a place. Some forms need a blank back so staff can write notes or add a stamp. Signage, flyers taped to walls, and labels only need one printed side.
Thin paper is another reason. Light stock can show print through from the back, which makes both sides harder to read. Letterhead, pre-printed forms, and heavy card stock may also work better on one side, depending on your machine.
Legal or government offices sometimes have their own rules for filed documents. If your clients or agencies ask for single-sided copies, follow their request. For everything else, the next thing to learn is how the machine flips the page in the first place.
How Do Automatic and Manual Duplexing Work?
Automatic duplexing lets the printer flip each sheet for you. Manual duplexing means a person flips the stack and feeds it back in.
Both methods give you the same two-sided result. The difference is time, attention, and how often someone loads the pages wrong.
How Does an Automatic Duplexer Turn the Page?
An automatic duplexer is a part inside the printer that pulls the sheet back after the first side prints. It turns the paper over and sends it through again for the second side. Some machines call this a duplex unit, and some just say “auto duplex.”
Most office copiers and multifunction printers have a duplexer built in. Some smaller desktop printers offer it as an add-on tray. Office models with auto duplex printing handle the flip while you walk back to your desk.
A duplexer is a moving part, so it can wear over time. Paper dust and humidity swings affect how smoothly sheets feed.
What Happens When You Duplex Manually?
Manual duplexing works on printers without a duplexer. You print one side, flip the pages, and feed them back to print the other side.
A common method uses odd and even pages. Guidance from the EPA’s duplexing guide lays out these steps:
- Print a test sheet so you know whether your printer prints face up or face down.
- Print the odd pages first (1, 3, 5, and so on).
- Keep the stack in order and reload it with the blank side facing the right way.
- Print the even pages in reverse order (for example, 12, 10, 8, 6).
Keep the top edge the same both times. Otherwise, one side comes out upside down. Some word processing software will even prompt you when it’s time to flip the stack.
Manual duplexing works for a short report now and then. For daily use, you’ll want the setting built into the machine, which brings up where to find it.
How Do You Turn on Two-Sided Printing?
On most computers, you turn on two-sided printing in the print dialog box that opens when you press Print. If you don’t see it there, check your printer properties.
The exact menu names change between programs and printer drivers. The steps below cover what you’ll see on most office setups.
Where Is the Duplex Option in Your Print Settings?
Start with the print screen in whatever program you’re using. Look for a setting like “Print on Both Sides,” “Two-Sided,” or “Duplex.” In Word, the duplex printing steps point you to the Settings area, where “Print One Sided” switches to “Print on Both Sides.”
If you can’t find it, try these places:
- Printer Properties or Preferences: Opens the driver menu for your specific printer.
- Finishing or Layout tab: Many copier drivers put two-sided options here.
- Printing Shortcuts: Some drivers bundle duplex into an “eco” or paper-saving preset.
- The copier’s front panel: For copy jobs, the touch screen has its own two-sided setting.
No duplex option anywhere usually means the driver isn’t installed right or the machine lacks a duplexer. An IT team can set two-sided as the default for every computer on your network. That saves staff from choosing it each time.
Should You Choose Long-Edge or Short-Edge Binding?
Choose long-edge binding for most portrait documents. The page flips like a book, so the back reads right side up when you turn it.
Choose short-edge binding for landscape pages or anything flipped top to bottom. Think calendars, wide spreadsheets, and clipboard handouts.
Pick the wrong one, and every back page prints upside down. Run one test sheet before a large job. With the settings right, the payoff shows up in the paper count.
How Does Duplex Printing Affect Paper Use and Office Workflows?
Duplex printing cuts the sheets needed for a multi-page document close to half. It also changes how jobs move through the printer.
The savings show up on paper orders first. They also show up in filing space, postage weight, and binder count.
How Many Sheets Does a 20-Page Document Need?
A 20-page document needs 20 sheets one-sided and 10 sheets two-sided. A 21-page document needs 11 sheets two-sided, since the last page has a blank back.
Now scale it. Say your office prints 50 copies of that 20-page handbook for new staff. Single-sided, that’s 1,000 sheets, or two reams. Two-sided, it’s 500 sheets, or one ream.
Your office-wide savings depend on how many jobs can actually switch. One-page emails, single-sheet forms, and documents that must stay one-sided save nothing. Long reports, handbooks, and packets save close to half. Count the multi-page jobs your office prints in a typical week, and you’ll see where the savings live.
The EPA’s tips on cutting office paper use describe duplexing as a common way most employees can immediately reduce the paper they use. Printing costs cover more than paper, too. Toner, service calls, and handling time all add up, and good print management habits trim waste alongside duplexing.
When Might Two-Sided Printing Slow Down a Job?
Two-sided jobs can run a little slower on some machines. The printer has to pull each sheet back, flip it, and send it through again.
On busy department copiers, that small delay rarely matters. On an older desktop printer, a 100-page job can take noticeably longer. Heavy paper and envelopes can also jam in a duplexer.
Watch for these signs that your setup needs attention:
- Jams that happen mostly on two-sided jobs
- Back sides printing crooked or smudged
- Staff skipping duplex because it feels slow
If staff avoid the setting, the machine may not fit your workload. That leads right into what to look for in a printer.
What Should You Check Before Choosing a Duplex Printer?
Check two things before you buy or lease: whether the printer duplexes automatically on your paper, and whether it scans both sides of an original. Those two features shape most daily paper work.
A machine’s spec sheet lists these features, but your real paper and documents matter too. Ask for a demo with your own stock.
Does the Printer Duplex Automatically on the Paper You Use?
Look for “automatic duplex” or “auto two-sided” in the specs. Then check the supported paper weights and sizes for duplex jobs. Many machines duplex letter and legal paper but not heavy card stock.
Dry winter air can make paper curl and build static, which causes misfeeds in the duplex path. Store reams sealed and away from heat vents.
Match the machine to your volume. A small team might do fine with a desktop printer. A busy office usually needs a multifunction copier with a sturdy duplexer. This overview of copiers for small businesses explains how size and speed line up with office needs.
Do You Also Need Two-Sided Scanning?
With duplex scanning, the machine captures the front and the back of every original without anyone flipping pages. You need it if you scan signed contracts, forms, or paperwork with notes on both sides.
Multifunction printers handle this in one of two ways. Some flip the page inside the document feeder. Others use two scan heads to read both sides at once, which runs faster.
Scanning both sides also helps you print less. Once files live in a searchable system, staff print only what they need. With the features sorted, the last step is putting the pieces together for your office.
Make Two-Sided the Default, Then Fix What Fights It
Start by making two-sided printing the default on every computer and copier you own. Then fix the machines that make it hard to use.
Equipment makes a big difference here. A machine that jams on every duplex job trains staff to avoid it. Keep the duplex path clean, use paper the machine is rated for, and replace a printer that can’t keep up instead of letting staff work around it. The next time someone asks, “What is duplex printing?”, the answer can simply be “our default.”

Frequently Asked Questions
Is Duplex Printing the Same as Double-Sided Printing?
Yes, duplex printing and double-sided printing mean the same thing. Both terms describe printing on the front and back of one sheet. Your settings menu might also call it two-sided printing.
How Can I Tell Whether My Printer Supports Automatic Duplexing?
Open the print dialog box and look for “Print on Both Sides” or a duplex option. If it’s missing, check printer properties or the model’s spec sheet. A copier that makes two-sided copies usually supports automatic duplex printing as well.
Should I Choose Long-Edge or Short-Edge Binding?
Choose long-edge binding for most portrait documents, since pages flip like a book. Use short-edge binding for landscape pages or calendars. Print one test sheet first to confirm the back side reads right side up.
Can I Print on Both Sides Without a Duplexer?
Yes, you can use manual duplexing. Print the odd pages, flip and reload the stack, then print the even pages. It works for small jobs but takes more time and care than automatic duplexing.
Does Duplex Printing Save Ink or Toner?
No, duplex printing uses about the same ink or toner, since the same content gets printed. The savings come from using fewer sheets of paper. To cut toner use, try draft mode or fewer color prints.
