Nope, I don’t use either of them. I use Powerdesk, which has many of the same functions built in.
Powershell is not a file management application, it's a shell/scripting environment. The out-clipboard bit is part of the SoruceForge cmdlets.
If you've got Windows 7, Powershell is installed by default. It was back-ported to run on Vista and XP SP2 and later. Both Powershell and the PSCX community extensions are free to download from MS and SourceForge, respectively.
Even without the community extensions, you send a directory list to your default printer from a PS prompt with:
dir c:/ -recurse | out-printer
You can also send it to a text file or to a .csv file to load into a spreadsheet or database.
If you go back and forth between Windows and *nix systems, Powershell aliases common commands to both Windows and *nix shell equivalents. Both of these will product the same result:
dir c:\ | out-printer
ls c:/ | out-printer
You can also invoke the native DOS version from within Powershell and send that to the printer using:
cmd /c "dir c:\ /b /s" | out-printer
