if that does not work reset the printing system and choose a correct driver as the Generic one is incompatible.

did you try resetting the printing system?

is the printer firmware up-to-date?

In addition to the recommendations by JimmyCMPIT try

Instead of the Generic PostScript Printer, use the PPD specifically for the Ricoh printer you have.

1. In the Printer Add window for Use, click on whatever it shows (e.g., Generic PostScript Printer) and a popup list will show.
2. Click Auto Select. In a short while, that should change to the PPD for Ricoh SP 311sfn/SP 311sfnw.
3. Click the Add button.

If with #2 above, a Ricoh printer does not show, then manually select it...

1. In the Printer Add window for Use, click on whatever it shows (e.g., Generic PostScript Printer) and a popup list will show.
2. Click on "Select Software..." and another window will open listing Printer Software on your computer.
3. Scroll down the list until you find a match for Ricoh SP 311sfn/SP 311sfnw and select/click it. Click the OK button.
4. Click Add button in the Add window.

HTH

Just to amplify what the others said - your symptoms mean your printer doesn't accept postscript as input (as in, you don't have the optional postscript card in it). You need to use whatever non-postscript driver is available for that Ricoh.

The Ricoh specs sheet says that printer is PCL 6 (HP-compatible). I think you might be able to use "generic PCL" for driver. Try it and let us know.

PS - the Ricoh site shows no current OS X driver for that model.

This Apple site shows no auto-downloadable driver, either:

If you don't find "generic PCL" for driver, install Gutenprint - it will give you a few choices:
