Well, the PPD you attached is NOT the original vendor supplied PPD,
it is for a different printer; and the C450 is a color device.

You should download the PostScript driver package for the C450 from
the Konica Minolta web site and extract the PPD from there.

The correct PPD should contain statements like
---snip---
*OpenUI  *SelectColor/Select Color: PickOne
*OrderDependency: 10 AnySetup *SelectColor
*DefaultSelectColor: Color
*SelectColor Color/Color:  "<</ProcessColorModel /DeviceCMYK>> setpagedevice"
*SelectColor Grayscale/Grayscale:  "<</ProcessColorModel /DeviceGray>> setpagedevice"
*CloseUI: *SelectColor
---snip---
To set b/w mode, you should (by editing the printer's PPD in /etc/cups/ppd or
by lpadmin or by the web interface ("Configure Printer" button)) modify it to

*DefaultSelectColor: Grayscale

PS: BTW, did your printer print anything? Depending on the printer's configuration
(by the service guy) it needs a bunch of PJL statements containing user ID and
authentication keys (e.g. "PUBLIC" for unrestricted use). I mention this as I
had to to some tweaks to get our C250 (which is a similar, a bit slower device)
working with CUPS.
