1. Check printer port and make sure TCP/IP port that matches the IP address of machine (underscores after IP are okay) is checked. Often see WSD port checked, which causes slow printing.

2. Check print driver and make sure driver is MPC4503 PCL6 (if PS is not installed on machine) or MPC4503 PS3 (if machine has PS installed). I stay away from Universal print drivers completely.

3. I generally download the current driver and do a fresh new install of printer as a rule if slow printing is present, but certainly if machine was assigned to WSD port. The driver on one of the PC's assigned to WSD was version 1.1.0.0. Driver I downloaded was version 1.4.0.0. You can find your version on the Windows test page. Don't know what version of driver gets loaded when doing an auto-discover/PNP install, but it seems insufficient and nearly all print speed complaints are from Windows 10 auto-configure installs.

4. Couple tips when loading printer - when searching for printer, immediately click "the printer I want to use isn't listed", then uncheck "query the printer..." box and select TCP/IP printer using the IP address. Lastly, check "replace current driver" and browse to your downloaded driver folder.

5. Any print file should be saved locally (I train folks to save file to desktop), then printed, so you are using local print protocols and the local driver. In other words, keep it to what you can control and explain. Printing from within a mail server or from a website adds degree of difficulty to printing that we often aren't able to support.

6. Make sure you open and print file from the best possible program for the print file. For example, Windows 10 wants to open .PDF in Microsoft Edge (indicated by e-PDF or some similar derivative), who knows how Edge manipulates us. Open the .PDF in Acrobat Reader, as most techs and IT are well familiar with that.

7. Print as image box should be checked as a test for .PDF files that print slowly. If there is marked speed improvement when box is checked, the print file likely has embedded data that must be translated by machine controller. This could be the case in Excel, Word, PP, and Adobe Pro or Photoshop. Similar to anti-virus or drug testing of athletes, the ability of the MFP to translate up-to-date and complex embedded print media is dependent on firmware that is usually lagging months behind. Thus, print as image bypasses the embedded info IF that is causing the issue.

8. Lastly, hook up laptop directly to the MFP and print their job if not proprietary or confidential, hopefully you can x-fer job to SD Card or thumb drive to accomplish this. Or print 25 pages of .PDF from a service manual from your laptop then do likewise from their local PC to compare and contrast print speed of the network. At this point, doing this is only to gauge the network impact on print speed, but the real causes in my opinion are the steps above. This step is only for folks who want instant gratification you only get by hooking laptop up directly.

Sorry if this is redundant or too wordy. And if some of my opinions above on WHY are inaccurate, my apologies.
9. Ensure ALL fw files are kept up to date this also makes a big difference
