I'm using an HP Laserjet 1200 on a WL500g Deluxe router with Oleg's 7g firmware. I have the 'standard' LPR printing installed according to the instructions and it all works reliably, just not very fast.

There's delay up to 20 seconds before printing a page. Especially when printing a more complex document, for example a PDF, with multiple pages, this is a bad experience.

Is there any known way to speed up the process, like downgrading or upgrading firmware, using different connections, using an usb stick to store print jobs, or something else?
