In Windows 3.1, the user can set the resolution of the output by selecting the Resolution option in the Advanced Options dialog box. Some printers are capable of printing in multiple resolutions and all printers can emulate certain resolutions (without changing the physical size of the dots). The list of hardware-supported resolutions can be viewed by moving the scroll arrow. Items can be selected from the list or an arbitrary value can be entered.
The halftone parameters (angle and frequency) do not update automatically when changing the hardware resolution. You must enter the correct values manually. Printers that only have one hardware resolution are acceptable.
