How to assign different attributes in model?

I have 6 fields and I want to set their attributes in model. 3 _print fields are auto saved like this.

def field1=(value)
  @number = Phoner::Phone.parse(value)
  write_attribute(:field1, @number.to_s)
end

def field1_print=(value)
  write_attribute(:field1_print, print_format(@number))
end

And I have these methods for field2, field2_print, field3 and field3_print. Can I put these methods in some .each method and iterate so I don't have these method duplication?
