I got myself in a right mess when I tried to print a CD on out our Epson P50. Cups (on Linux) does allow adjustments to print area and to get things centred but I managed to confuse myself (I think in part, sometimes using CD 5" when I was modifying CD Custom or something like that).

I only wanted one CD with a Norwich City logo on it for my nephew but think I must have printed about 20 before I got it right.

I suppose the good news is that it is set for future use and using a central print sever, these adjustments would hold good for any PC/Android... in the household but we rarely want to print CDs. I suppose it is a feature to have but this printer's most common use is printing 4x6 card.

(Yep, some people still do like to have or be able to enclose a "postcard" in an envelope. And I suppose along similar lines, I was quite surprised to find that one bit of kit a niece had taken with her for her Europe trip [from Australia] was a Polaroid - I remember the older ones but was unaware of the modern ones.... And I seem to have rambled a long way from CD printing... )
