PRINT ISSUE WHILE IMPOSITION - strange issue - Please help me out

Hi there,

I do have fuji xerox docucolor 5540i printer and driver installed in my windows 8.1.

When I print single ( vector ) page from corel x6, it comes out perfect no issue, let say A5 flyer single on A3 page.

Problem : When I impose 2 or 4 up, some of the text comes out bit wiggly,thin, twisted and it doesn't look sharp and It will be at same on all copies, eg 4*A5 impose on SRA3.

I checked with technician and he said its something with program.

I don't what to do ? Can anyone  please help me out ?

Thanks a lot in advance.
