Thanks to all for the replies ...
@ reghakr, Tews, & fseal ... as I stated in my original post there are no programs to uninstall in "Programs and Features" and there are no start up items in msconfig related to Brother.
@ richc46 ... the printer was around a long time and predates any restore points.
@johnhoh ... won't that create problems at start up if some registry setting is looking for an executable that isn't there?
@ Frostmourne ... Thanks for that suggestion, I'll have a look at the Revo uninstaller and let you know how I made out.
