Firefox can't use CUPS Printer

[Nirjhor <nirjhor@xxxxxxxxxxxxxxx>]

Hello,

I have a CUPS printer (HP) enabled and all good. My firefox is not from 
repo. I am using a localized version of firefox downloaded from firefox 
website. Right now I can print to a pdf and from that PDF I can print 
the text. Can I locate the printer in Firefox in any way?

I'm on Arch KDE and I am using hplip if that's of any help.

Thanks
