Slow response to printing on iMac Pro

Recently my iMac Pro has taken a long time to respond to printing. It takes a minute to load the print dialog, then another minute if I change the paper size, and again if I print to PDF.


My MacBook Pro (on the same desk) responds instantly.


The printer is also on the desk, but I'm using AirPrint. It is a Brother MFC laser.


What might be slowing down my iMac Pro, and how can I speed things up again?

Hi Gio2021,


We suggest booting into safe mode to see if the issue persists. This will help to isolate further. You can find steps for doing so here: How to use safe mode on your Mac - Apple Support


Additionally, it may help to reset the printing system on your Mac as this could resolve unexpected issues with printing: Reset the printing system on your Mac to solve a problem - Apple Support


We hope that helps.


Take care.

Hello Shannon, and thank you for replying swiftly to my question. I have read through the steps in Solve printing problems on Mac – Apple Support (AU), although the problem is not that I can't print from the iMac Pro. There is no problem printing (eventually). It used to be instant, but now each small step in the process takes up to a minute to respond (Press Print, Select Paper, Print to PDF).


So, even if I print to PDF it takes 2-3 minutes each time. This wasn't a problem a few months ago.


I have my MacBook Pro beside it, and that responds instantly on each step. So I feel something is slowing up my iMac Pro, but I'm not sure how to troubleshoot that.


If you have any further advice, I would be most grateful.


Thank you again for reaching out. I do appreciate it.


Cheers,

Gio
