|One option is to "install" the printer twice, the first with the printer properties set to Grayscale and the second with the printer properties set to Color.|
Now you can choose the "color" printer only when you need it and leave the grayscale one as the default.
That is what I do at home. My shared printer is installed on all 4 systems twice so everyone has a Grayscale default and an optional Color printer. This saves on color ink.
You can take it one step further and use a Macro attached to a button to print to the Color printer when required.
I use this to print to a cheap Brother printer in my office when I don't need the quality of the networked laser printer. It prints to the Brother and then resets the laser to Default. You could do something similar to print to your "two" printers.
(I removed the actual server and printer name)
ActivePrinter = "Brother HL-1440 series"
Application.PrintOut FileName:="", Range:=wdPrintAllDocument, Item:= _
wdPrintDocumentContent, Copies:=1, Pages:=""
ActivePrinter = "\\server_name\printer_name"
