Customers have reported issues when printing MacDraw II 1.1 under System 6.0.x (e.g. 6.0.5) with background printing and LaserWriter 7.0. These users have reported that the graphics in a document will not print, parts of the drawing was missing. If they take the illustration to another application, (e.g. MacWrite II) the objects will only print on some pages, while only text will print on other pages.
To see if this is the issue, have user create a new folder and move System, Finder and LaserWriter from the System Folder into this new folder. Restart. The issue will go away.
I believe matching the system to the LaserWriter version (System 6.0.x with LaserWriter 6.0.x or 6.1) with associated files (e.g. Print Monitor and Backgrounder 6.1) will correct the issue on a permanent basis.
