We've got an annoying problem with Autocad LT 2008/2009.
First, we've installed all Service Pack and patches for those Autodesk products.
If we print from Autocad LT on our Canon printer with color or color pro option selected in printer drivers (no grayscale), with and without .pc3, and :
* The workfile has not been saved before printing, after print user can't do anything, if he tries to save or trace a line, he's got a "DBX CAS 4" error. User must restart Autocad and reopen the file, very annoying bug.
* The workfile has been saved before printing, in this case all works perfectly
This bug is only on Autocad LT and our Canon printer, it works with anothers printers and does not seems to affect Autocad FULL.
Canon drivers are 5.2.3790.3959, Canon printer is IRC2880-J1
