print multiple entries at once

When I’ve selected multiple entries in the entry list, is it possible to print them all with one single command?

Not directly. EagleFiler prints what is displayed. If you have multiple records selected, you can print the source list, the records list, or the viewer showing the summary of how many of each type of record is selected.

However, it’s possible via AppleScript:

tell application "EagleFiler"
    set _records to selected records of browser window 1
    set _files to {}
    repeat with _record in _records
        copy _record's file to end of _files
    end repeat
end tell
tell application "Finder"
    print _files
end tell
