I own a HP Laserjet 3700 and I simply can't get collate to work. I click the collate button on the print dialog, and am using the correct driver, but it still won't work. If I tell an app to print 10 copies, it prints 10 copies of the first page, 10 copies of the second page, etc. Then I have to manually sort them. This crushes my work flow. Can anyone help?
