Photoshop :: CS6 - Elements 8 - Print Not Printing Completely?

From time-to-time, I seem to have had a temporary printing issue with Photoshop Elements 8, whereby the photo I was trying to print would not be printed completely, but part of it would be cut off, as if the printer's print-head would not be receiving the data from Photoshop past a certain point in one particular plane.
 
Up to this morning, I had never encountered any printing issue with Photoshop CS6, which I have had, and printed with, for the past 6 months or so. This morning, however, I encountered the same issue, for the first time, using Photoshop CS6. It is now printing properly again, but why do I occasionally encounter this with either software?
 
When I normally print, I like to print photos to exact sizes, but which vary greatly, and so I prefer the technique of creating a new blank A4-sized document and dragging my photo into this document and, by using Free Transform, size the photo to my exact requirements, before printing onto good quality A4 glossy or sometimes matte paper.
 
What happened this morning was that, using the technique above, I was trying to print a very small passport-sized photo over to the right-hand side of a sheet of A4 paper, with the blank document in the portrait orientation. My photo was only partially printed, and cut off past a certain point in the horizontal plane. By dragging my photo further towards the centre of the blank A4-sized document and reprinting onto the same sheet of A4 worked fine. After experimenting a little by printing the photo in various places on the same sheet of A4, I discovered that the photo was not printing past a certain point, in the horizontal plane, towards the right-hand side of the sheet of A4.

This cut off point was consistent in every printing attempt. There was a certain point to the right-hand side of the sheet of A4, where, in the horizontal plane, it would simply not print past. By measuring this cut off point in the horizontal plane, it is 4.8cm from the right-hand edge of the sheet of A4, in its portrait orientation.After resetting all tools, turning the PC and printer off and then on again, launching Photoshop CS6 and retrying, it seems to be printing correctly again, and I am able to print my photo anywhere on the sheet of A4, without anything being cut off past a certain point.
