I have a web based kiosk which can print pdf coupon at the kiosk printer (MAC OS + CUPS driver) from a JSP page in Firefox browser, by using one of the options of firefox--- "print.always_print_silent
option." , the print window popup would not show up and the printing is perfect. however, due to Firefox version update so frequently and always have trouble to match up with the Adobe flash version, so I have to disable the update of Firefox----please refer to the attachment for details, the good thing for Safari browser is it never show this annoying update alert on the page. So I am thinking maybe switching the browser from Firefox to Safari is the solution. the biggest challenge to adopt Safari is that I have no idea how to make Safari to print silently------ the popup window always show up after user click on print button.
I did google around, however, not seen any practical solution yet.
Another option is to use Chrome, but decide not to after seeing some troublesome response on the internet.
The same question had been asked by others:
Any practical solution would be appreciated, but exclude the cloud printing service because those kiosks will not be able to talk to the third party cloud.
