HP Officejet Pro 8500a prints slowly over wireless on Cisco Linksys Smart Wi-Fi Router EA6500

Question

I have the HP Officejet Pro 8500a. I recenrly change my wiress router to the Cisco Linksys Smart Wi-Fi Router EA6500.
Nearly every time I print, the documement remains "pending" for at least several minutes, sometimes as long as 20, until it finally starts printing. Once it starts printing, the document is printed quickly.
It doesn't matter the size of the document and the time it remains "pending." I've done test pages with just the word "test" in a Microsoft Word document, and it will remain in "pending" for well over five minutes.
If I print over the USB cord, there are no delays.
I need help. I can't figure out how to remedy this long delay when printing wirelessly.
On a side note in case this is helpful, the Linksys router does have a priority setting where you can select up to three devices for priority access (faster connection?), which seems to be more for bandwidth-intensive devices. I tried adding both the laptop I'm printing from and the printer to this priority list, but that did not improve the print connection speed.
Advice please! Thank you.

Hi Jim-Gr,
I understand you have an Officejet 8500A that has started printing very slowly after switching routers. I'm sorry to hear this has happened but will certainly do my best to assist you.
I appreciate you advising that you have tried connecting the printer via USB and it does make a huge difference. I'm also assuming your previous router didn't go this slowly either. With the things you have tried, my assumption is that it's a setting in the router that needs to be changed. If you're not sure how to change things in your router you can generally call the router company and they will walk you through it.
First you will want to ask them if there are any firmware updates for your router, if there are have them perform the update. If it is up to date already then have them make sure your router is broadcasting at a frequency of 2.4 GHz as that's the only frequency the printer works with.
Second, you will want to make sure the following ports are open:
UDP: 427, 161, 137, 138
TCP: 9100, 9220, 9500, 137, 139, 427
Once all of this is updated, then I would suggest you power cycle everything (turn off the printer and the PC, pull the power on the router for 30 seconds and then turn the other two back on once lights are back to normal) and try again. This should allow your printing speed to go back to normal
Hope this helps, have a great day!
