| ↳ | [android.print.PrintAttributes.Resolution](https://developer.android.com/reference/kotlin/android/print/PrintAttributes.Resolution#) |
This class specifies a supported resolution in DPI (dots per inch). Resolution defines how many points with different color can be placed on one inch in horizontal or vertical direction of the target media. For example, a printer with 600 DPI can produce higher quality images the one with 300 DPI resolution.

## Public constructors
### Resolution
Added in[API level 19](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
Resolution(
id: String,
label: String,
horizontalDpi: Int,
verticalDpi: Int)
```
Creates a new instance.
| Parameters ||
|-----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `id` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html):The unique resolution id. It is unique amongst other resolutions supported by the printer. This value cannot be`null`. |
| `label` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html):The**localized** human readable label. This value cannot be`null`. |
| `horizontalDpi` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html):The horizontal resolution in DPI (dots per inch). Value is 1 or greater |
| `verticalDpi` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html):The vertical resolution in DPI (dots per inch). Value is 1 or greater |
| Exceptions ||
|--------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------|
| `java.lang.IllegalArgumentException` | If the id is empty or the label is empty or the horizontalDpi is less than or equal to zero or the verticalDpi is less than or equal to zero. |
## Public methods
### equals
Added in[API level 19](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun equals(other: Any?): Boolean
```
Indicates whether some other object is "equal to" this one.
The`equals`method implements an equivalence relation on non-null object references:
- It is*reflexive* : for any non-null reference value`x`,`x.equals(x)`should return`true`.
- It is*symmetric* : for any non-null reference values`x`and`y`,`x.equals(y)`should return`true`if and only if`y.equals(x)`returns`true`.
- It is*transitive* : for any non-null reference values`x`,`y`, and`z`, if`x.equals(y)`returns`true`and`y.equals(z)`returns`true`, then`x.equals(z)`should return`true`.
- It is*consistent* : for any non-null reference values`x`and`y`, multiple invocations of`x.equals(y)`consistently return`true`or consistently return`false`, provided no information used in`equals`comparisons on the objects is modified.
- For any non-null reference value`x`,`x.equals(null)`should return`false`.
An equivalence relation partitions the elements it operates on into*equivalence classes*; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters ||
|-------|--------------------------|
| `obj` | This value may be`null`. |
| Return ||
|------------------------------------------------------------------------------------|------------------------------------------------------------------------|
| [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | `true`if this object is the same as the obj argument;`false`otherwise. |
### getHorizontalDpi
