PIXMA G510 and G610: Firmware update issue

[diogofarias]

I have a Pixma G510 and a G610, after the latest firmware update they no longer print my photos centered on 4x6 paper with borders. When I set it to print without borders, I lose at least half a centimeter on all sides of the paper. I need help to fix this bug or find a way to downgrade the firmware. I haven't been able to resolve this issue using any other printing methods. Original image

I use original inks and 10x15 cm 180g glossy photo paper from the Spiral brand.  

These photos were printed on the G510 with firmware version 2010.

Tested it on Windows versions 10 and 11.

Any help would be greatly appreciated.10x15BerderlessHagaki 100x148mm
