If you’ve ever worked in access control, retail loyalty programs, or event ticketing, you’ve probably held a plastic card with a smooth, dark stripe along its back: a magnetic stripe. For years, I’ve fielded a very common question from clients, prospects, and even new team members at our company, a card printer supplier: “Can a card printer print magnetic stripes?” The short answer is yes—but only if you’re using the right kind of printer, and there’s a lot more to that answer than a simple “yes.” Let’s break this down, based on decades of work supplying and supporting card printers for businesses of all sizes. Card Printer
First, let’s get clear on what we mean by “magnetic stripe printing.” Magnetic stripes (often called magstripe for short) store data as tiny magnetic particles arranged in alternating north and south poles. When a card swipes through a card reader, the reader’s head detects those magnetic patterns and converts them into usable information—like a customer’s loyalty ID, a building access code, or a event ticket validation.
Now, a standard desktop card printer you might buy for home or small office use? It only does what’s called “direct printing” and “retransfer printing.” Direct printing uses heat to transfer colored resin or wax ribbon onto the surface of a card, perfect for photos, names, and logos. Retransfer printing adds an extra layer of clear film to protect that printed content, great for cards that will see a lot of wear. Neither of these technologies can interact with magnetic particles. To print or encode a magstripe, you need a printer built specifically to handle that technology—what we call a “magstripe-enabled card printer.”
Here’s how that works. Magstripe-enabled printers have two key components that set them apart. First, they have a magnetic encoding head. Unlike the print heads that lay down color, this head generates a magnetic field that rearranges the particles in a blank magstripe, either writing data to it (encoding) or adjusting its magnetic pattern to fix errors (sometimes called “printing” in the broader sense, even if it’s magnetic rather than visible). The second component is a magstripe lamination station or a dedicated slot to feed and treat the magstripe. If the magstripe is already laminated to the card (a common setup for most plastic cards), the printer ensures the magnetic head can reach it without damaging the lamination. If you’re working with blank cards that have a separate magstripe strip, the printer aligns that strip perfectly before encoding.
But let’s talk about the limits here, because it’s not a one-size-fits-all. For example, our company supplies two primary types of magstripe-enabled printers: desktop models for small businesses (like cafes running loyalty programs or small offices with 50–500 employees) and industrial models for larger operations (hospital networks, event ticket companies, retail chains with thousands of cards to issue).
Our desktop magstripe printers, for instance, work with all three standard magstripe formats: Coercivity (the strength of the magnetic field needed to read the stripe). Most of the cards you use daily use 300 oersted (OE) low-coercivity (LoCo) magstripes. These are inexpensive, work for simple access control and basic loyalty data, and our printers encode them flawlessly. Then there’s 2750 OE high-coercivity (HiCo) magstripes, which are far more durable—they resist erasure from magnets, heat, and physical wear, making them ideal for things like employee ID cards that get passed between doors daily or credit cards (which rely on HiCo to hold sensitive data). Our industrial magstripe printers are calibrated specifically for HiCo, because they generate a stronger magnetic field that can reliably write to and read from HiCo strips without error.
A common misconception we run into: people think magstripe printers can print visible content (like a logo, name, and photo) on the front of the card and encode the magstripe in one pass. That’s absolutely possible, and it’s one of the biggest benefits of using a magstripe-enabled printer. Instead of running a card through a direct printer first, then through a separate magstripe encoder (which adds time and risk of misalignment), a combined printer does both in a single process. That cuts down on labor, reduces the chance of damaging the card mid-process, and ensures the printed content lines up perfectly with the encoded data on the magstripe.
But here’s where mistakes happen, especially for businesses new to ordering card printers. If you try to use a standard direct card printer (not magstripe-enabled) with a third-party magstripe encoder, you’re running into problems. First, alignment. If you don’t feed the card perfectly into the encoder after printing, the magstripe might be too high or too low, so the card reader can’t pick up the data. Second, compatibility. Many low-cost third-party encoders aren’t calibrated for different card thicknesses or magstripe types, so you might encode a LoCo stripe that gets erased after a few swipes, or a HiCo stripe that fails the first time a magnetic door reader scans it. Third, error rate. Separate encoders often have a higher error rate—around 1–2%—compared to a integrated magstripe-enabled printer, which can get error rates below 0.1%. For a business issuing 10,000 cards a year, that means 100 extra defective cards, which adds up in cost and time.
We’ve seen this firsthand. Last year, a regional fitness chain came to us after trying to set up their own member cards. They bought a standard direct printer and a $500 external magstripe encoder from an online marketplace. In the first month, 12% of their cards failed at gym door readers—either the stripe was unreadable, or the name printed on the front didn’t line up with the member ID encoded on the stripe. They’d spent $2,000 on supplies and equipment, and had to reprint 500 cards, costing them hundreds more in labor and lost member trust. When they switched to our mid-range magstripe-enabled printers, their error rate dropped to under 0.2%, and they cut their card production time by 30% because they no longer needed a separate step for encoding.
Another key point: even if you have a magstripe-enabled printer, you can’t “print” visible content directly on the magstripe itself. The magstripe’s surface is made of delicate magnetic particles—any direct printing (with heat or ink) would damage the particles, making the stripe unreadable. That’s why all magstripe-enabled printers print visible content on the plastic base of the card, and then encode the magstripe strip that’s embedded or adhered to the surface right next to the printed content. There’s a small gap between the print area and the magstripe, which the printer’s software calibrates to avoid damaging the magnetic material.
What about newer technologies, like smart cards (with a chip) or contactless cards (with RFID)? Can a card printer that supports magstripes handle those too? Many magstripe-enabled printers are hybrid, meaning they can handle multiple card types. For example, our industrial printers support magstripes, proximity chips, and even NFC/RFID tags, so a business can issue a card that works for access control (RFID), payments (HiCo magstripe), and building entry (chip) all in one. But that’s a separate feature—you don’t lose magstripe capability when adding those features, as long as the printer is built to support them.
Let’s also talk about maintenance, because that’s a big part of keeping a magstripe printer working correctly. Unlike standard printers that only need occasional ribbon replacements and cleaning, magstripe printers require regular calibration of the encoding head. Dust or residue from plastic card stock can build up on the magnetic head, which weakens the field and leads to encoding errors. We supply our customers with cleaning kits specifically for this—small swabs and cleaning solution to gently wipe the head every 1,000 cards, which keeps error rates low. If a customer skips this step, they’ll start seeing more unreadable magstripes, but that’s a fixable issue, not a sign the printer can’t do magstripe printing at all.
Now, if you’re someone shopping for a card printer, how do you tell if a model is actually magstripe-enabled? A quick way: look for features listed as “magnetic encoding,” “HiCo/LoCo compatibility,” or a dedicated magstripe slot on the printer’s body. If a product page only mentions direct printing, retransfer, or photo ID printing, without any note about magnetic stripes, it’s not built to handle magstripes. Another red flag: models that market themselves as “all-in-one” but don’t list HiCo or LoCo support—many of these skip the magnetic head component to cut costs, so they can’t encode magstripes at all.
We’ve worked with everything from small nonprofits issuing volunteer ID cards to large theme parks printing 10,000 event tickets a day, and the demand for magstripe-enabled printers is only growing. Even as contactless and chip technology becomes more common, magstripes remain popular because they’re low-cost, easy to use, and compatible with millions of existing card readers around the world. That means businesses still need the ability to print and encode magstripes, and the right printer makes that simple and reliable.
So to circle back to the original question: Can a card printer print magnetic stripes? Yes, but only a printer designed for magnetic encoding—not a standard desktop direct printer. The key is to choose a model that supports the coercivity you need (LoCo or HiCo), integrates encoding with printing to avoid alignment errors, and includes the maintenance features to keep the magnetic head working properly.
