Hi Stuart,



This may not be a fault in Word, per se, but in the printer driver for your printer. Rather than using 'mirror margins', you may get better results by using the same inside & outside margins together with a gutter.

Hi Paul,

Thanks for your response. I still get the problem whatever printer I have as default, even with my 'print to file' PDF printer.

I don't know if the 3mm front/back misregistration is related to another problem I'm having with these documents. This is that my custom page size of 173mm width X 246mm height (untrimmed standard paperback size) is very close to B5 (176mm X 250mm). Word appears to save my custom size but automatically resets the page size to B5 when the file is reopened, ignoring the dimensions I typed in previously. The difference between my custom 173mm width and the B5 width of 176mm is 3mm. Could be a coincidence but I suspect this may be the problem. If I could get Word to save my custom dimension and not default to the nearest standard size, I could check this out. Any ideas on this second problem

Thanks again for your help. Stuart
