I use InDesign daily. You can print to a non-postscript printer if you export the document as a PDF. Open the PDF and print it.
If you want to print direct from InDesign then you will need a RIP (e.g., Adobe Press Ready) but first make sure that your printer is supported by Press Ready, check the Adobe web site.
I use InDesign and Press Ready with an Epson SC1520 printer. In Addition, I also export PDFs from InDesign and print them on an Epson SP1270 (the 1270 is not currently supported by Press Ready).
