(CNN) New York Gov. Andrew Cuomo signed a bill Wednesday that bans school districts from arming teachers, part of several laws he's signed this week to strengthen gun regulations in the state.

Under the provision, which takes effect immediately, educational institutions cannot authorize any employees to carry firearms other than school resource officers, law enforcement and security guards. President Donald Trump has advocated for arming teachers as a way to prevent school violence.

"The answer to the gun violence epidemic plaguing this country has never been and will never be more guns," Cuomo said in a statement.

Cuomo signed another measure Wednesday that tasks police with setting statewide regulations on gun buyback programs. He also signed laws expanding safe storage laws in homes with children under 16 and outlawing weapons "undetectable by a metal detector," including 3D-printed guns.

Within a week of last year's shooting in Parkland, Florida, Trump suggested arming teachers and school staff to improve safety at schools.
