No meu PC, NÃO consigo usar
o comando:

uiv.browser.type('${KEY_CTRL+KEY_P}');

uiv.sleep('2s');

uiv.browser.type('${KEY_ENTER}');

Não esta dando erro, apenas não acontece nada e o fluxo segue normal para os próximos passos.

Hello,

This is expected behaviour, not a problem with your PC. uiv.browser.type sends the keys to the page, inside the tab. Ctrl+P is a browser shortcut, not a page shortcut. Chrome does not run its own shortcuts (Ctrl+P, Ctrl+T, Ctrl+S, zoom with Ctrl++ and Ctrl+- …) when the key arrives that way. That is why there is no error: the key was sent, the page received it and ignored it.

There are two solutions:

1. Real operating-system keyboard (uiv.desktop.keyboard)

This needs the Ui.Vision desktop app installed. It produces a real OS keystroke, which reaches the browser and also the print dialog:

uiv.window.focus();                               // bring the browser window to the front
uiv.desktop.keyboard.type('${KEY_CTRL+KEY_P}');
uiv.sleep('2s');
uiv.desktop.keyboard.type('${KEY_ENTER}');

The second step (Enter) must also be uiv.desktop.keyboard. If the destination is a real printer or “Save as PDF” with the native Windows dialog, that dialog is outside the page and uiv.browser.type never reaches it.

2. Without the desktop app: open printing from the page

This opens the same print window. To confirm it with Enter you still need the real keyboard from option 1.

uiv.evaluate('setTimeout(() => window.print(), 0)');

Rule of thumb:

  • (Only) For keys inside the page (fields, the site’s own shortcuts), use uiv.browser.type.

  • For browser shortcuts, system dialogs and other programs, use uiv.desktop.keyboard.type.
