HPLaserJet Pro M15a offline on OSX 10.9.5

[Venda]

Hi, I have managed to install and print on HP Laserjet Pro M15a. But then trying to install another (older) printer and following some online suggestions, I have deleted hpplugininit.kext and installed older software and now HP Laserjet does not work. I have of course tried to reset the printing system and reinstall the printer but it wont work and shows offline. The test page will come out though. Could you please help?

@Venda, Welcome to HP Support Community!

Follow the steps below-

ensure that the printer is up to date with its firmware and Mac is up to date with its software. If you are unsure you may use the links below to update the printer firmware and Mac software:

Update printer firmware

Update software on Mac 

Reset the printing system-

1. Click the Apple menu, and then click System Preferences.

2. Click Printers & Scanners, Print & Scan, or Print & Fax.

3. Right-click (or Control + click) anywhere inside the Printers window, and then click Reset printing system.

4. Click Reset or OK.

5. If prompted, type your username and password, and then click OK.

The printing system resets.

6. Turn off the printer, wait 5 seconds, and then turn on the printer.

7. Wait until the printer is idle and silent.

8. In the Printers window on the Mac, click the Add button.

Select your printer from the list, and then click Add. It might take a few seconds before your printer displays in the Printers list.

If you still have issues, we can run the disk utility to isolate and resolve the issue-

1.)Choose Apple menu > Restart. After your Mac restarts (some Mac computers play a startup sound), press and hold the Command and R keys until the Apple logo appears, then release the keys.

2.) Click Disk Utility, then click Continue.

3.) Choose View > Show All Devices.

4.) In the sidebar, select the disk you want to repair.

5.) Click the First Aid button.

a) If Disk Utility tells you the disk is about to fail, back up your data and replace the disk. You can’t repair it.

b) If Disk Utility reports that the disk appears to be OK or has been repaired, you’ve finished. You can click Show Details to see more information about the repairs.

c) If Disk Utility reports “overlapped extent allocation” errors, two or more files occupy the same space on your disk, and at least one of them is likely to be corrupted. You need to check each file in the list of affected files. Most of the files in the list have aliases in a DamagedFiles folder at the top level of your disk.

>> If you can replace a file or recreate it, delete it.

>> If it contains information you need, open it and examine its data to make sure it hasn’t been corrupted.

d) If Disk Utility can’t repair your disk or it reports “The underlying task reported failure”, try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall macOS, then restore your backed-up data.

Hope this helps! Keep me posted.
