You could try putting your file names in a single file, one filename per line. Copy this single file to a folder that is being monitored by a PlanetPress Watch Folder input.
Then, use a splitter task to split the file on every line. For every iteration, your data file will then contain only one line, which is the name of the document to print.
Finally, add a Printer Queue output and select Dynamic name as the document to print. Use the data selector to set this dynamic name to read the first line of your data file.
That's it. You must make sure documents are available to your printer, though.
