Thanks George.

Got a reply "Due to the Oregon voucher now being the entire page, we are no longer able to print the mailing address on the voucher.  The mailing address for the voucher is included in the Letter and Filing Instructions.  We might recommend you request to Oregon that they include the mailing address on the vouchers."

so...most likely not going to happen...too bad...the old vouchers helped eliminate address errors or late payment fees for those that need to mail payments.
