+# [Printer tester](https://github.com/julien-cpsn/typst-printer-tester)
+
+Generate printer tests directly in Typst.
+For now, only generates with CMYK colors (as it is by far the most used).
+
+I personally place one of these test on all my exam papers to ensure the printer's quality over time.
+
+## Documentation
+
+To import any of the functions needed, you may want to use the following line:
+
+```typst
+#import "@preview/printer-tester:0.1.0": square-printer-test, gradient-printer-test, circular-printer-test, crosshair-printer-test
+```
+
+### Square test
+
+```typst
+#square-printer-test()
+```
+
+### Gradient test
+
+```typst
+#gradient-printer-test()
+```
+
+### Circular test
+
+```typst
+#circular-printer-test()
+```
+
+### Crosshair test
+
+```typst
+#crosshair-printer-test()
+```
