I had a similar problem once, prints not coming out exactly the way I like them or batch plotting and some prints coming out portrait or landscape. So I wrote a script for it, and it uses the -plot command, and puts in the settings each time that you set. The only problem is you should have the scriptpro that comes with express if you have it. If you do I can send you the scripts for batch plotting.
From there, using the scripts I created, you pick your drawings you want the script to apply too, pick your script, hit enter and get some coffee.
For your reference, when using -plot, it overrides the drawings settings it has stored for what it thinks it should plot out on. That way I was able to specify, what printer, what plot style, what layout, what scale and so on. Type it in and you'll see the opitions it will give you.
