Also know, how do I put 4×6 photo paper in my HP printer?
Slide the paper width guide all the way to the left. Lift the Out tray and remove any paper that is in the In tray. Line the photo cassette up with the far right edge of the In tray. Gently slide the photo cassette into the printer until it snaps into place (see Figure 3).
Similarly, what side does photo paper go in printer? Place your photo paper in the tray with the glossy or printable side facing down. Hold the paper by the edges to avoid fingerprints on the glossy surface.
