Who said it doesn't? The settings are in the Print dialog box. One of the tabs has a check box labeled 'Separations', and when ticked, other tab allows you to specify exactly which separations you'd like to output. Depending on your print driver, there may also be a 'Reverse Output' setting somewhere too.
However, it's rare that anyone would need any of these features these days, even if you are involved in prepress: normally you just use an appropriate PPD to create a PostScript file that's passed onto a specialist RIP for your particular device. It's not wrong to use the print dialog box, just a little outdated and inflexible, especially when it comes to imposition.
If you're not involved in prepress, then why do you want to do these things? If your printer can't read a Quark file, I'd go somewhere else. You're not getting paid to do their job for them.
