Printing 60 images of pencil drawn/written A4s on Legal paper, 55 copies each. HP K5400DN loaded with Quad pigment inks. Vista and XP HP K5400 driver.
Qimage Ultimate V2012.100 and 2010.102 Qimage Studio. 16 bit greyscale Tiff files but 8bit Tiffs and Jpegs made of them show the same flaw. Not all, say 1 in 5 images have it.

Tiffs are 20,9 x 297 mm size, 389 PPI. Loaded at original size. Driver asks for 600 PPI rendering resolution. Resampling set at Max, Pyramid, Sharpening 6. Colour Management OFF. Most image files go straight without issues. 1 in 5 are delivering an almost nice image but a rectangle or square is not rendered at the bottom of the page slightly left of the center in HP driver preview and is not printed at the trailing edge in the print. Between 40 mm and 80 mm wide, 40 mm high. If I switch resampling in Qimage OFF and all settings the same thing does not happen. Tried on two systems Vista 64 and XP 32 with the Qimage versions mentioned and the compatible HP drivers. If I Print to File with the same settings it does not happen (printer settings route). If I load that created 600PPI file then in Qimage and print with resampling and sharpening OFF it will print without the flaw. Something happens when Qimage is resampling the file and the driver receives it. Photoshop printing does not have it for the same files.

Mike, Thank you.


Adjusted the driver more and I will see if that makes it reliable for next 2000. Must be the extra quality Qimage adds that does it.
