Can SDI LPD run as a system service?
See Running LPD as a System Service.
Port 515 is in use by another application
You will receive this message if you start a second instance of SDI LPD because the first instance is already using port 515.
If the Windows LPD Print Service is active you will receive this message. The Windows LPD Print Service uses port 515. You must turn off this service to release port 515. To turn off the service:
Windows 7, 8, 10 and 11 |
Control Panel, Programs and Features, Turn Windows features on or off, Expand Print and Document Services, Uncheck LPD Print Service |
Windows NT, 2000 or XP |
Control Panel, Add/Removed Programs, Add/Remove Windows Components, Other Network File and Print Services, Details, Uncheck Print Services for Unix |
License Code Questions and Answers
The license code is not valid for this release.
The license code you entered is for an older release of SDI LPD. The license code is generated for a specific release and will not function with newer releases of TN3270 Plus.
The product release level is three digits separated by periods, for example, 3.4.0. The license code only checks the first two digits, so a license code created for 3.4.0 will work with releases 3.4.0 through 3.4.9. In addition, license codes for release 3.3 and above will work with the next higher release. For example, a release 3.4 license code will also work with release 3.5 (3.5.0 - 3.5.9). However, if you try to use a release 3.4 license code with release 3.6.0 or higher you will get the above error message.
