HP printer not printing characters anymore

Question

Hello,

My HP OfficeJet 4657 printer has suddenly stopped printing black characters, only the colored header prints.
If I print the document in all black (including the header): the problem is the same: the header prints in black, but not the text...
My printer is equipped with generic cartridges that have been working well until now (although I faced serious printer blocking issues about 4 months ago due to commands intentionally sent via my Wifi connection by HP...)
Needless to say, HP seems to illegally block a printer that does not use their original cartridges whenever they wish.
Do you think this new incident is caused by HP via my Wifi?
Or does this phenomenon have nothing to do with HP’s (fraudulent) manipulation, and in that case, what could the solution be?
My computer = Mac with macOS Sierra version 10.12.6

I would like to get an opinion and a solution (if possible)
Thank you in advance

Configuration: Macintosh / Safari 11.0.3

To be honest, it’s quite strange in the sense that it should either not print anything or have defects in the printout.

Maybe it's the format of the file to be printed?
If you put the text in color, does it print correctly? (test it with just a part to avoid emptying the cartridge)

Hello,
Have you solved your problem? If so, congratulations and good for you.
I have the same printer and therefore cartridges.
I think it comes from clogged nozzles of the black cartridge. Have you tried cleaning them with a suitable product (demineralized water, solvent, or something else)? What does the ink level indicate (determined by the number of pages printed)?
I also have a problem with this printer, but slightly different from yours.
Original HP cartridges from the start and no issues. The last black cartridge showed some signs of weakness and before it ran out, I refilled it with HP printer ink.
Result: the printer prints some documents in black but not others.
I’ve tried cleaning the print head, nothing. Sometimes the black indicators show up and sometimes they don’t.

Yesterday, I bought another HP black cartridge, but before opening and installing it, I would like to understand the problem and know if there is a solution.

Thank you for any help or ideas.

Hello,
I found the origin of my problem: it's the quality of the ink used. Too old.
I bought a new bottle and everything is working perfectly again.
I hope this helps....
