You can do the same thing to parallel ports (LPTx) to test them, too. But some
printers expect a whole page of text to be sent before they'll actually print
anything (this is usually the case with laser and inkjet printers). A lot of
modern printers (lasers and inkjets) won't print plain text, either, but
require special "startup codes" before they'll print anything at all. Older
printers (dot matrix, daisy wheel, etc.) will normally let you print single
characters or single lines of plain text. Bottom line is that you have not
provided enough information to do much troubleshooting.
