One could trace the protocol between the phone and the network to see if it conforms generally. Specifically is another issue.
Re:Never buy Epson printers on Saturday March 12, 2016 @07:10PM (#11275433)
This is on a Mac. I wanted to see if the firmware bugs would be fixed by using their firmware update tool. The printer itself times out when attempting an on-device firmware upgrade. The downloaded update utility just attempts to grab a new firmware image from an IP which is non-responsive.

It can't scan over AirPrint if it has gone to sleep, it only can accept print jobs via IPP if you want it to WOL. So I have two printers configured, one via AirPrint for scanning and another via IPP for printing. There are so many low hanging firmware bugs that it makes me think the same folks wrote healthcare.gov

This is par for the course in brother firmware, https://gist.github.com/seanjensengrey/4223dc23d1f7cc95a157

This is not true, I owned a 700$ multifunction printer scanner, copier, everythinger and it required me to hack the cartridges to print black, it always put shitty yellow tracking dots on all printouts. Don't send more business to Brother.

They have the worst software (on printer and in driver) of any printer company I have come across. Their driver installers download random bits from IP addresses in Japan with zero encryption. The hardware is stellar, the software is cringe worthy.

If you have an opinionated style guide, I would love to read it. Something like this [0] but for Java.

Yeah, that chart is painful. Talking about absolute dollars with no basis is not productive.

Disks internally have lots of extra space to handle errors and are not pushed to the limits of their physical storage. Amazon could have partnered with a disk manufacturer or written their own firmware to have disks that are somewhat lossy but 3x of what reliable drives provide.

This should be on this list http://www.amazon.com/How-Solve-It-Modern-Heuristics/dp/3540... single best technical book I have ever read.
