Product: HP DeskJet Plus 4120 All-in-One Printer

i have a printer called DeskJet Plus 4120. 

when i need to print tickets with a QR or a Bar-code on it, i always have a problem.

the QR or Bar-code don't look like they should.

the QR or Bar-code is not filled with the black color, it only has black squares with white inside them.

i have tried to print in HIGH quality mode also, and it don't work either.

 

i have tried to reinstall drivers, update drivers. i have the HP-Smart app on my widows 11 system. 

i have tried with new original ink cartridges.

 

hope you can help me

kind regards mie
