You only have issues with the ProSeries tax program sending to the printer or all programs that send to the printer?

I know anytime I update ProSeries 2018, I cant print from ProSeries 2018 until I reboot the whole computer...not sure if it affects other years as well, Ive just gotten so used to a system reboot after I install or update ProSeries, I just do it automatically now.

Just ProSeries

@Eileen28 Which HP printer?
Is the problem with all years of PS?
Has there been a windows update recently?

Believe it or not. Have 2 (new) printers HP Laser Jet MFP 428 fdw both give me the same problem.Purchased a couple of months apart.  Have had GREAT service with HP in the past.  They may still
be good because all the techs I've had look at them say it's not the printer the computer is just not
communicating with the printer.  Have also tried the settings, devices, etc earlier on, didn't work for me.

Never had a problem before with HP or PS.  With all the techs I've used I'm sure there has been an
update.  Maybe more than one.  Have been with ProSeries more than 10 years

happens with all years of PS or only a certain one?  Can you print to PDF, then print the PDF?

Only happens with the current .  Don't know about the PDF must give it a try (tomorrow)

I keep a USB cable connected to the WiFi printer, so that when I have trouble with it as WiFi, I plug in. That hasn't happened for a while, now. When I had a mix of W7 and W10 devices, it seems that the printer got hijacked by one or the other. You simply install that printer as two different devices, so that you can print to the hardwired connection or as WiFi.
