I recently installed v. 146 for both FireFox and Thunderbird on my laptop which is running Windows 11 Pro (Version 25H2 / Build 26200.7462). Since the upgrade to v. 146 I have been unable to use my older HP printer (Laserjet 2300d) on both products. When I try to print a browser page or e-mail using either the printer icon or the "File/Print" menu selection, the print dialog comes up like normal. However, when I click on the "Print" button, my screen flashes, the dialog box disappears, there is no indication from the printer that a file has been sent and no document is found in the print queue. My newer HP printer/scanner (Officejet Pro 8130)works fine, as does printing to my older printer from MS Edge. So, the issue is with the Mozilla products. Using "Troubleshooting Information" and clearing the Printer cache has not resolved the issue for either FireFox or Thunderbird. Nothing else like this shows up in the knowledge base. Do I have to retire my older, but dependable and inexpensive to use, laser printer in order to continue using FireFox/Thunderbird or is there a software solution?
