--- Comment #35 from Mike <[email protected]> --- Ha, first thing I tried and I found the issue causing the "Invalid Argument". First off, dashes in printer names (queue name) are fine, spaces are not allowed. So, with print manager, I set up an print queue, USB direct connect, took the default ppd driver, saved. Kate shows double-sided just fine, prints, all works good. Now, go back to print manager, change the printer driver and choose IPP Everywhere, then Apply. This is the fail for invalid argument. Technically, it should fail, because CUPS can't make an IPP connection to that printer configured with the USB direct connect address (ipps://usb/ENVY.....). So, that's actually legit, it's just the message is cryptic and not complete. Secondly, we should probably have a better validation for the IPP Everywhere option showing on the driver select dialog. -- You are receiving this mail because: You are watching all bug changes.
