There is no supported method for preventing the AppleShare Print Server 4.0.x software from printing error pages. However, we have a ResEdit patch that will prevent AppleShare Print Server 3.0.x, AppleShare Print Server 4.0.x, and AppleShare Print Server Pro from printing error pages. Here are the directions:
1) Use ResEdit to open the AppleShare Print Server application.
2) Open the "EXOP" resource with an ID of 128; it should be the only one.
3) Change the first four zeros (0000) to ones (1111).
4) Quit ResEdit saving the changes made to the AppleShare Print Server application.
Now the AppleShare Print Server application should no longer print error pages.
Note: This is NOT a supported solution.
