It's a strange request, perhaps, but I keep coming across this problem:
special forms I have need to be printed double-sided. What I've done all
these years is to request that the sheet be printed X-number of times and
then I turn the printed forms over and put them in the manual input tray and
send the print job again for the same number of copies as just printed. It
would be so neat if I could just click on the button that says, "print 10
copies double-sided" or whatever.

Is this even possible, though? I've thought through other solutions but
everything I've come up with just wouldn't work, I believe (i.e., having 2
copies of the same sheet. I've never figured out how to get 2 sheets to
print one one side, and the other on the flip side!). No, the very best
solution would be to somehow get XL2K to send the job twice but print the
job double-sided. Must admit that I've also tried sending the job 2 and
double-printed but XL2K didn't like that and nothing short of the manual way
above has ever worked.

Thanks.
