Photos not centered when printed

Question

Every time I print a photo with iPhoto either the top (in Portrait mode) or the left side (in Landscape mode) is shortened. I cannot find an adjustment to correct the lack of centration. Can anybody help me with this?

Yes! ...all the obviuos things I've ruled out. These include drivers and options/settings. I even made sure to try and isolate the problem by removing the shared driver on the server and installing the latest drivers on just one computer to compare but got no differing result..all the computers sharing the driver on the server produced the same results as the islotated computer with direct access to the printer with the newest driver. So it's not the software nor the drivers that causes this problem. The problem is more noticable when printing on SRA3 (450 x 320mm) with 250gsm - 300gsm.
You are right about what the tech would say +/- 1 - 2mm tolerance. There is no problem when copying straight from hardcopy on the machine ...all tests conclude prefect registration.
I'm corrently using PCL drivers because they are better at handling graphics...I'm wondering if Postscript drivers would sort the problem out?
Other that that the only wa7y I can see to work arund this issue is to offest the spread/page in the software environment ....it's only when I want to print 2 sides ...as the tray won't print 2 sides on greater than 120gsm I use the bypass tray to print then work & turn to print the other side...if I didn't offset the page in the software/application, side 2 would be out of registration by upto 4mm.
Let me know if can think of any other way I can resolve this issue...I'm sure that the registration was pretty good previuosly ...may have been 1-1.5mm difference but now it's almost 3-4mm!
