Duplex and grayscale with generic PostScript driver?

Question

Duplex and grayscale with generic PostScript driver?

Does anyone know if there is a way to allow the user to select options such as duplex or grayscale when using the generic PostScript driver?

Or, if this is not possible, is there a third party generic PostScript driver that does offer these options?

The printer manufacturer's driver does offer these but sends QPDL instead of PostScript to the printer, which means we can't charge for the print job correctly.

Thanks,

Hello Dan,

The Generic Postscript driver included with OS X does give you the option to print duplex but not b/w (grayscale). To enable duplex, select the Generic PS printer in Printers & Scanners, click on Options & Supplies and then select the Options tab. Here you can enable the Duplex unit.

So if the vendor does not have a supporting PPD that provides duplex and B/W then you could try the Fiery Express Driver which you can get from EFI. Note that you have to register to gain access to the driver.

Turns out, we can accomplish our objective by modifying the Samsung driver PPD, removing the rasterizer and replacing it with a cups-postscript filter.

We can then apply this PPD to the printer by using the CUPS web interface (enabled with "cupsctl WebInterface=yes") and voila, the driver now speaks PostScript but still has all the manufacturer options available.
