USB devices disconnect on sleep

This problem has been plaguing me for awhile. When my 27" iMac (5k) sleeps it disconnects a label printer I use to print postage labels for my business as well I found my Bose USB sound system turns off as well.


What will happen is I try to print a label but the printer is shown as paused under printer settings and the job is in queue, If I click "resume" in print queue then I see an error "cannot send data to printer". I will have to run the printer off then on again every time my Mac sleeps.


Also my Bose speakers have a LED on the controller, it's normally white (meaning on and ready) and amber (when I touch it to turn it off) but when the Mac wakes from sleep it's always amber meaning I have to turn it on or I have no audio.


The speaker is a mild annoyance and I only mention it to show it's not 'just' the printer with an issue, it's some USB items. The printer however is a major PITA as it's set back in a cabinet and I have to pull it out, reach behind it to urn it off and on again and half the time I end up pulling out the power cable or USB cable while doing this.


I have never had these troubles before and it's getting me frustrated. I found a temporary work around by setting my CPU to never sleep. I would however like to find a better fix for this so it works right.


The printer is seen by the USB in the Mac when it's not working, going into about this Mac / system report / USBI can see the Zebra printer is there but it can't communicate with the software.


I have reset my SMC, made sure allow Bluetooth to wake is on changed USB ports, rebooted (several times) even ran hardware test (no issues found).


I am using OS 10.13.6 (I have multiple software that will brick if I upgrade any further so that's not an option).


Any ideas for a fix? or is this just a quirk of the OS or this 5k iMac (only had for a year).
