try updating your printer drivers: http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?oid=141552&in foType=Downloads
Walter what is the reason which you need an older version of InDesign? Is it to be compatible with other users utilizing an older version?
In general Adobe does not offer older versions of our software for sale. If you do need to purchase an older version, to obtain a license/serial number, you will want to work with a third-party reseller.
I see then I believe Kglad's advice is on track with starting with updating your printer drivers. I have also moved this discussion over to the InDesign forum as the Users in this forum likely have additional suggestions.
Also if you can please turn off your e-mail signature if you want to respond via e-mail. Your responses are going to a public forum where the information is accessible by anyone. I have edited your previous response to remove the signature.
I have the software I just cannot find a serial number. The older version printed seamlessly.
Did you have a license for the earlier version? If so, and you registered it, you can retrieve your serial number from your account at the Adobe Store.
