So, in reference to the on going issue where HP won't allow for after market toners and use a firmware upgrade to block them and unable the printer, I need to replace 14 Pro MFP Printers, what do you recommend?
Oh, I found a solution that worked for a couple of months; reverting back to a June, 2020 firmware upgrade. But, now they seem to be blocking that as well. It no longer works for the CLJ Pro M452mw's I have 4 or the CLJ Pro M180 and M181s, I have 5. So, i will no longer be an HP shop. I need a new brand. 14 printers to start, then a wide format. I no longer want to support HP treating people like this. I've been an HP shop (all HP printers and desktops, quality assurance machine, common area machines) to over 25 years.
I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).
