ExcelliPrint doesn't list my printer

Q: The printer I want isn’t in the list when I set a queue’s output to Printer, or its jobs fail with “the printer couldn’t be opened”.

A: ExcelliPrint® prints from a Windows service, so it can use printers installed for the computer, not printers installed for one Windows user. A network printer you added for yourself (by connecting to \\server\printer while logged on) belongs to your user only.

Either:

• Install the printer for the computer. An administrator adding it in Windows Settings > Printers & scanners is enough. Then choose it in the queue’s Printer output.
• Use the shared printer directly. Type its name, \\server\printer, in the queue’s Location, then click Add User under Credentials and enter a Windows user that can print to it. ExcelliPrint connects to the print server as that user for each job; the password is protected by Windows.

Windows allows one set of credentials per server at a time, so give every queue that uses printers or folders on the same server the same user. See the ExcelliPrint manual, sections 6.2 and 6.4.
