My client uses HP Laserjet 4250 with his accounting software, which requires DOT4 USB driver. I have been able to install this printer and print from other programs, however, I need to be able to add addtional driver for the accounting software to print.
I was able to do this once by downloading DOT4x64 USB universal driver from HP, and get it going. However, I had to re-image the PC because of malware, and now the same file, Dot4x64.msi will not run. I tried to run it on my PC, and it runs fine. I disabled McAfee, and still cannot run.
My PC and his PC are both Windows 10 Pro, 64-bit machines. Is there a way to force a driver without running Dot4x64.msi? I do see the USB designated for Laserjet 4250 in the device manager, but cannot update the driver.
