need help with plotting e-size in 2000i

[Premierpaper]

hello, so im hoping someone can help me. im using autocad 2000i with windows 7 64 bit, a canon ipf750 plotter with driver version 4.53 (stock driver). eversince we switched to windows 7 my e-size dwgs have all been printing 2:1 scale. some even 4:1 !! so when i go to plot, i have to choose half scale on most of the e-size files otherwise they come out double the size and it requires me to babysit the plotter. my dwgs are drawn at 1:1 and the viewport scale is correct. even when i go into the windows plotter settings there isnt anything unusual that stands out. for the record its only the e-size dwgs. if anyone can help out that would be awsome. thank you

You have some sort of scale-setting in your driver, or PC3 file, or on the device itself unless you're really missing a setting on the PLOT dialog box or the pagesetup you have chosen to use.

There seems to be a driver "optimized for autocad" on their website released a couple of weeks ago, maybe you need that too.

I suspect you need to contact Canon Support while you are over there to see if they have other ideas.
