Hi Alvin, welcome to the forum.
However, I am wondering why there is a white strip not being printed, I have set the border expansion to minimum in order to allow my crappy image border to show through, is that the reason? It does seem right in the image preview, so would this be a hardware limitation of the printer?
The simple answer is "yes", it's a common problem with borderless printing although I'm a little surprised that you have it "with border expansion to minimum" in the driver; my R800 still expands a little even on minimum.
The reason why there is expansion on the borderless setting is to allow or paper feed inaccuracy on the printer. If the white strips are consistent then it can be compensated for in Qimage by tweaking the page margin settings. I recommend that you leave the expansion setting at maximum in the driver and set Qimage to disable it from the Page Formatting-Borderless Overspray-Expansion menu.
Read Help-Contents-Qimage Functions-Borderless Overspray/Size Expansion. That tells you how to compensate for paper feed errors and white strips. Once set (you'll need to test a couple of times), save as a Print Set-Up for future use.
NB. make sure the paper guides are as snug as possible to minimise errors and improve consistency.
Terry.
