Get various errors -  
Access violation at address FFFFFFF3. Read of address FFFFFFF3.
Access violation at address 008e6994 in module evoerp.exe.  Read of address 00001193
Access violation at address 004BCFE2 in module evoerp.exe.  Read of address 00000180.
Basically, some of these errors (especially the FFFFFFF3) are endless loops and with all of them you have to exit EVO.
 
But - if you don't preview and just send direct to printer - no problems.
