Hi Crotonmark30,

So we can better assist you, please reply with the following information:

1.  What operating system is on  your computer (Windows XP, Vista, 7, 8 or version of Mac OS)?

2.  What brand and type of envelope are you trying to print on?

3.  Is it just the first envelope that has the black dots printed on it, or subsequent envelopes as well?

4.  How many envelopes are being loaded into the printer at one time?

We look forward to hearing from you!
