PRINT / COMPARE / TROUBLESHOOT
Photo quality printer test
Engineering preview: usable draft patterns, not a physically validated release. See validation limits.
Real photographs required
The portrait, landscape and fine-detail slots require verified real photographs with PDF/web permission and at least 300 dpi at their printed size. No substitute images or downloadable photo PDF are published until those materials pass review.
For now compare the text, grayscale and color tests; they cannot verify skin tones or photo detail.
Before you print again
Does requesting a print mean it printed?
No. The browser can request a dialog, but cannot tell whether you cancelled, sent the job or received paper. Check the preview and the physical result.
Why are there two paper sizes?
Each PDF has a native Letter or A4 page box. Choose the same size in the printer dialog, use Actual size / 100%, and disable headers, footers and Fit to page.
Can this sheet diagnose my printer?
It is a comparison aid. A generic sheet cannot identify a failed part, measure ink remaining, certify colors or replace the manufacturer's model-specific checks.
