Thank you very much for the quick repair!!!
the HP428 laser printer was "weaned from chips", now I can use compatible cartridges that are sold without them.
I advise you, competent guys, they know what they are doing!
Of the minuses, I will not say anything bad!!!
Of the pluses, speed, accuracy, and most importantly quality. Keep it up !!!
A good company, I have been servicing my office equipment with them for several years. I like everything very much, quickly and on time. The prices are great!!!
