OfficeJet 6800 when printing PDF the file size dramatically increases when spooling

[LDNTPA]

Hi, I am hoping someone could help with an odd problem I am experiencing when printing PDFs. I have 2 x HP printers; 1 x OJ 8600 and 1 x OJ 6950 - The issue is when printing PDFs to the 8600; on watching the print queue, the file that I send to print (less than 800kb) spools to in excess of 25Mb which in turn makes a large document take a very long time to print. To remedy this I have tried removing and reinstalling the HP printer software, removed Acrobat Reader, used a different app for PDFs, set the printer not to spool and print direct. None of these have helped, I have also tried USB / Network connections to the device and there is no change. If I send the same document to my other printer (6950) the file size doesn't increase. From this I come to the conclusion that either a Windows 10 update (I'm running 1809 Pro) or HP AIO software update has caused this. Can anyone help?

Many thanks in advance

@LDNTPA,

Thank you for posting your query on HP Community,

Let's try to uninstall the printer from the root level and then reinstall it by following the steps below: 

• Press “Windows key” + “r” to get the “Run” window.
• Type "services.msc" to get Services – Go to “Print spooler” – Right-click and “Stop” the service.
• Now again open "Run" - Type “spool” and ok - Go to PRINTERS folder - delete everything in that folder.
• Go to services again - Start the print spooler.
• Now check for issue resolution.
• If the issue persists, also try clean installing the printer drivers. Here are the steps:
• First, unplug the USB cable from the printer if present.
• Go to Control panel – Programs and feature – Select all the HP OfficeJet printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
• Restart your computer.
• Please click here (Please enter the product number and then select the Operating system and version of Windows before downloading and installing the full feature printer software).
• Connect the USB cable if prompted and follow the on-screen instructions to complete the installation.

Alternatively, I would suggest you can try to update the printer firmware. 

If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website. Alternatively you can also try to update the printer firmware directly from the printer control panel.

For more details on how to update, please use this link: HP Printers - Updating or Upgrading Printer Firmware

Next thing, as a work around, you can also try to print using HP Smart app - HP Printers - Using the HP Smart App (Windows 10)
