Lightroom changes aspect of photo when printing

When printing from Lightroom Classic OR Photoshop on my desktop computer, the print preview (and the print) have the aspect changed and the color is slightly off.  I am using a Canon Pro-100 printer. By aspect, I mean people's faces are narrowed, a bowl is nrarrowed, etc. I have uninstalled, reinstalled Lightroom. Didn't help. I have uninstalled, reinstalled the printer and downloaded the current drivers. Didn't help. I reset the printer to factory defaults. Didn't help. I have compared my settings to those of my friend with her computer running Windows 10 and the same printer. Settings are the same for printing. Her photos come out matching when she sees on the screen. I have re-calibrated my monitor. Didn't help. I then opened a photo in Windows Picture Viewer and selected print. The colors and aspect match exactly. This tells me that something is off with Lightroom Classic and Photoshop, but I don't know what to look for or change! In Lightroom Classic, if I select a 4x6 paper, select portrait, turn off all Image Settings, the aspect is correct. However that prints the photo very small in the middle of the 4x6 paper. If I select landscape in the print settings, and turn on "Zoom to Fill" and "Rotate to Fit", the aspect of the person's face is narrowed. This does NOT happen to my friend when she has those exact settings for landscape. Since it doesn't happen with the Windows Photo viewer, I have to believe it is not the printer, but the Lightroom Classic and Photoshop programs. It does not make a differnce if I select Normal-size, Borderless, Fit to Page, or Scaled in my printer properties.  HELP!
