ExpressPCB and Double Sided PCBs

Guys, I'm working on a power supply for my MMC and I'm using ExpressPCB and a laser printer to make the board. The problem I have with it is that the top copper layer needs to be reversed when I print. Express PCB does not give me an option to do this. Short of doing a print-screen and having a resizing nightmare, how do you all handle this?

The perversity of nature is nowhere better demonstrated by the fact that, when
exposed to the same atmosphere, bread becomes hard while crackers become soft.

I realize that, but I'd like to "print" the PCB here at home once for QC'ing before I spend the cash on havng them build one professionally. For my normal PCB stuff, I use a program in Linux that is amazingly called "PCB", but I decided to do this one in ExpressPCB for the simple fact that I could just order the board from the program, but like I said, I'd like to QC the board myself before I spend money on it.

Screen capture the layout, pop it into a GOOD paintbrush program, flip it, resize it to correct output size, print the flipped image....

Bob,
I was hoping to avoid having to do that. I was hoping that someone knew a way that I could print the native PS and just have it print flipped.

Jon,
I like to "print" one off, use it and see how it is to work with. I'm a firm believer in designing something twice, because the you will (almost) always come out with a better product the second time, which is why I didn't want to spend the money on the proto board the first time.

If you do the printscreen route, make sure you resize the image to be exactly the normal size or else components won't fit (I found that out the hard way).

My print driver has an option to mirror the print job, but it never works. I'm using an HP LaserJet 4050 (PostScript). I also have a PDF Writer that uses a PostScript driver. What printer/driver are you using?

That's what I was thinking. My HP LaserJet 4050 has Postscript installed which was an option over PCL because PS·is much more advanced. Nevertheless though, the mirroring function in my PS driver does not work. Maybe I should try the latest driver from HP themselves instead of relying on the M$ driver.

Again, if it doesn't work with PS, then try PCL.· One is bound to work (at least in my experiences with printer drivers).
