Firefox has some nice options for printing, but I dont see how to change the print program itself (lpr). What I WANT to do is to get things to print double sided (duplex). What I have done in the past is to tell Mozilla that the print program was 'ipr' rather than 'lpr' and use this as a filter to affix << /Duplex false >> setpagedevice near the top of the postscript output. So, how do I change the print program (from lpr) in Firefox? -or- Is there a better way? -- Reg.Clemens reg@xxxxxxx
