NiceLabel on-premises licenses are perpetual. There are two licensing options:
Single-user. Your license allows you to run one instance of NiceLabel on a single computer. You can use an unlimited number of printers from this computer.
Multi-user. Your license allows you to run an unlimited number of NiceLabel instances on an unlimited number of computers if these computers can communicate with each other and belong to the same domain. The number of printers you can use is limited by the number of “print seats” that come with your license. All your computers use the same license key.
If your multi-user license regularly exceeds the number of print seats, you should purchase a license upgrade.
NiceLabel Cloud licenses are based on the subscription model.
For licensing details, read Licensing and Activating NiceLabel.
All NiceLabel multi-user applications track the number of printers you use in your Licensed Printers list. If nobody uses a printer for seven days, NiceLabel automatically removes this printer from your list. This frees up a print seat for another printer.
To ensure uninterrupted sharing of your multi-user licensing information, NiceLabel requires opening ports 6772 and 6773 on your computer. When you start a NiceLabel application, the NiceLabel Proxy Service sends broadcast packets to these two ports and receives replies from all other NiceLabel applications in your labeling environment.
A printer counts as a single printer when:
Multiple computers use the same shared network printer’s IP address.
Another computer also shares and uses a locally connected printer.
Printer model names are hard-coded in your printer driver. You cannot change model names, but you can edit your Printer Names.
If you access your printer from more than one local port, this counts as multiple printers. If you switch from one local port to another (for example, from LPT1 to USB) and print, this counts as multiple printers.
You can use Web Printing to share your labels or solutions with external partners outside your LMS environment. NiceLabel includes these printers in your Licensed Printers list. Each used printer takes one license seat.
Use printer reservation for your mission-critical printers. Reserved printers are always ready for printing. Adding other printers does not remove reserved printers from your Licensed Printers list.
NiceLabel automatically removes unreserved idle printers from your Licensed Printers list after seven days.
To reserve or unreserve printers in NiceLabel Designer, Automation, and Print:
Go to File > Options > Licensed Printers. The Licensed Printers table opens.
Check/uncheck Reserved for your printers.
To reserve or unreserve printers in Control Center:
Go to Printers > Licensed Printers. The Licensed Printers table opens.
Select your printers and click Reserve printers or Unreserve printers.
You cannot manually remove printers from your Licensed Printers list. NiceLabel removes unused printers from the list after seven days.
A multi-user license allows you to use your purchased quota of printer seats. If you exceed this number, NiceLabel activates a 30-day grace period and a warning message appears (which doesn't affect your printing). The grace period allows you to continue printing with double your license seats, even when you temporarily exceed your license allowance.
The Licensed Printers list purges unused printers after seven days. This reduces the number of active printers and frees up license seats.
After the grace period, if your printer usage list contains more printers than license seats, the number of available printers automatically reduces to match your license quota. Active printer seats remain only for your most recently used printers.
Upgrade your license to use more printers, or wait until your unused printers automatically disappear from your Licensed Printers list after seven days.
For more information, read Using too many printers.
When you host NiceLabel LMS on-premises on your own equipment, we require all instances of your multi-user license to belong to the same domain or workgroup.
If you need separate domains, you can only use the same multi-user license if you first establish a two-way trust relationship between your domains.
NiceLabel applications use a proxy service to communicate multi-user licensing information:
Computers with NiceLabel Designer, NiceLabel Print, and NiceLabel Automation use NiceLabel Proxy Service on each computer. Open port 6772 TCP/UDP for inbound communications.
Computers with NiceLabel Control Center use the NiceLabelEPMProxyService and port 6773 TCP/UDP for inbound communications.
Computers with both Designer and Control Center installed use both NiceLabel Proxy Service and NiceLabelEPMProxyService allowing incoming traffic on ports 6772 and 6773 TCP/UDP.
