Hi,
I bought the above printer a couple of weeks ago as I'm just starting to get to grips with all this sublimation malarkey! Anyway when I was pressing the medium size place mats & ipad covers from BMS I realised their was little to no room for error when pressing them and with the ipad covers I always got a part of the cover still having a white border due to the printer insisting on leaving a white border round the image no matter how big I made the image. Anyway after searching Google and getting told this printer did not do borderless printing I played with the settings and found a solution so I thought I'd share it with other users of this printer in case they too had the same issue. Anyway rambling over onto the solution.
in the powerdriver settings next to paper size click the '+' button
name the form name anything you want but 'borderless' made sense for me
change units to metric
set the width to 23cm & height to 30cm (i only needed borderless printing in width so you might need to set the height to 32cm if you require borderless printing for the whole A4 sheet)
click add form
click OK to closedown the powerdriver settings and then open the powerdriver settings again and a new paper size will be available called 'borderless'
when you want to print an image make sure the width of the image is at least 21.5cm and ensure you set the paper size to your newly created borderless in the powerdriver settings and it should print to the very edge of the paper.
I'm printing from photoshop so I also unchecked center image and set the top and left position to 0 (zero) and also unchecked scale to fit media
I found by doing this it it printed to the edge which gave me more of a bleed area around the width for the ipad covers so no more white border and more room to manipulate the printed image when printing the medium sized place mats.
I hope this helps someone who was in the same position as me and thanks to everyone for making this such a great forum for beginners like me to start wanting to sublimate anything that moves
