DTF RIP without a dongle: how account licences work

Many converted DTF printers run from a Windows PC with a small USB key in the back. While the key is there, nobody thinks about it. The day it is missing, the RIP does not print, and a full order waits. This post explains what dongle licensing is, why vendors use it, and what goes wrong in practice. It also shows how an account licence like ZoroPrint’s works, including its limits.

What dongle licensing is, and why it stops you

A dongle is a small USB device that holds the licence for a program. The RIP looks for it when it starts. If the key is not there, the RIP does not print. The licence is the key itself, not your name, your invoice or your computer.

That is the whole problem in one line: your right to use software you paid for is a piece of plastic. AcroRIP, the RIP that most converted Epson L1800s and L805s ship with, works this way. It costs $375 one-time plus a USB dongle (official price since April 2026). As our AcroRIP alternatives article puts it: lose or break the dongle and the RIP stops.

Why vendors use dongles

There are honest reasons for a dongle. They are worth knowing before you judge one.

• Piracy control. A program that cannot run without a physical key is harder to copy than a file. For a small vendor in a market full of cracked copies, that matters.
• One edition per dongle. The key carries exactly what you bought. AcroRIP sells its desktop and wide-format versions separately, one edition per dongle.
• The licence moves with the key. Unplug it from one computer, plug it into another, and the licence goes with it. No account, no activation, no internet.
• No licence server. The vendor does not have to keep an online service running for the licence to work.

A dongle does not stop piracy completely. Many converted printers arrive with a cracked copy of AcroRIP. To run without the USB key, these cracks install dongle emulators: low-level drivers that fake the key and run with deep access to your computer. That is a risk for you, not only for the vendor.

What breaks in practice

The dongle works until one of these things happens. None of them is rare in a busy shop.

• The key is lost or broken. A USB key is small and sticks out of the computer. It gets knocked, bent, or taken home in a pocket. Without it, the RIP stops until you get a replacement from the vendor or reseller.
• “No dongle detected.” The key is in the port, but the program does not see it. The cause can be a loose port, a USB hub, or a missing or old dongle driver. The message is different in each program; the result is the same: no print.
• The key is in the other computer. You design on the laptop and the key is in the PC in the print room, or the other way round. Only the computer with the key can print.
• One edition per key. A desktop printer and a wide-format printer need two AcroRIP editions, each with its own dongle.
• A Mac with Apple Silicon. A dongle needs its own driver on each operating system, and a Windows-only RIP has none for macOS. In a virtual machine on an M1–M4 Mac, Windows runs in its ARM version, and drivers must be built for ARM. The dongle and the printer also go through USB passthrough from macOS. That link can drop when the Mac sleeps or attach to the wrong side. Details in DTF RIP for Mac.

Online activation removes the key, but not every limit. CADlink / Fiery Digital Factory uses an online activation code per computer, and the licence is tied to one computer. Apple Silicon Macs are explicitly unsupported. Flexi DTF Pro uses online activation with a subscription.

How an account licence works

ZoroPrint does not use a dongle. The licence belongs to your account. When you sign in on a computer, that computer gets a signed token that proves it may print on your plan. There is nothing to plug in and nothing to lose. You do not install a dongle driver on macOS, Windows or Linux.

The rules depend on the plan. We put them here plainly, because they are the trade-off for having no dongle.

• Paid plans (Solo $72/year or $8/month, Shop $168/year or $19/month) keep printing for up to 30 days offline. Connect to the internet at least once in that time.
• The Free plan needs an account and an internet connection for every print. Before each job prints, the RIP takes one Free job from our server. No connection means no print.
• Free gives you 30 print jobs a month on 1 computer, with no card. Solo also covers 1 computer.
• Maintenance prints (channel test, head alignment, nozzle check) never use a Free job.

To move to another computer, install ZoroPrint from the download page and sign in with the same account. The new computer gets its own token. Free and Solo cover one computer, so the licence is on one computer at a time. If the old computer is broken or stolen, contact us. You do not have to find a piece of plastic first.

The licence does not change how the RIP prints. It sends jobs straight to the printer over USB or the network (raw port 9100), with no Epson driver. See what the RIP does and how to connect the printer.

When a dongle actually makes sense

An account licence is not better for everyone. A dongle wins in one clear case: the licence must move physically between workshops, and those workshops have no internet. You plug the key into the computer at one site today and into the computer at the other site tomorrow. No server is involved.

Our model does not suit that case well. The Free plan cannot print offline at all. Paid plans print offline for up to 30 days, then need a connection. If your printer sits for months where there is no internet, a dongle-licensed RIP can serve you better, as long as you look after the key.

For most small shops it is the other way round. The computer is online most days, the printer stays in one place, and the real risk is a lost or broken key on a busy day.
