Printing #10 Envelopes

[Wally]

Not sure if this is the right place to ask this, but...

Using Open Office and an Epson Stylus Photo R340 printer, I am unable to 
print #10 Business Envelopes. CUPS is the printer driver, as installed 
in Ubuntu.

Pages and photos print just fine. But I need to rotate the document 90 
degrees to print. Or tell the printer that there is an envelope in it.

A #10 envelope is too long to fit thru the printer length wise, so you 
must insert it sideways. But no matter what I do in the software, 
switching between landscape or portrait, it will only print across as if 
a piece of paper was in the printer. And if set to portrait, just cuts 
off the end of the address when printing on paper.

Any help would be greatly appreciated.

Thanks
WALLY
