More Sony Goodness

After the recent improvements to the older Sony printers (Most notably, the UP-CR10L is now confirmed working after a bunch of little modifications!) I decided to take another look at some more recent (but not necessarily new) models:

  • UP-D898/UP-X898
  • UP-DR80MD
  • UP-CR20L

They're a diverse bunch, but share a common data format and communications protocol built on top of what appears to be standard HP-PJL.

I believe I've successfully figured out the data format for all of these models, and written the intial backend parser. The next step is to write the Gutenprint rasterizer code, but anything beyond that will require access to one or more of these models so I can obtain details about the communication protocol they use, and of course, test my code out.

I still don't know how to obtain media type and counter information out of the older Sony models (UP-DR150/UP-DR200/UP-CR10L) too, so without someone out there willing to perform sniffs of Sony's Windows or OSX drivers doing their thing (or send me a printer!) I'm not likely to be able to progress beyond the current state of affairs.

There are a bunch of other Sony models, mostly consumer-focused, that may be worth trying to support too, but I'd rather spend my time on models that are still commercially relevant. Of course, hardware in hand trumps everything else!

Anway. Back to the bit mines..

Sony UP-D895 & Sony UP-D897


Over the past month or so I've been figuring out the Sony UP-D895 & UP-D897 Medical/Scientific Thermal printers. They're most commonly seen on ultrasound workstations, but can be found nearly everywhere.

I'm happy to report that Gutenprint (5.3.2-pre or newer) now has full support for these two models with feature parity with the Windows drivers, including basic status & error reporting.

In the process of figuring out the UP-D895/897, I discovered a lot more about other Sony printers, resulting in the UP-DR150 & UP-DR200 getting basic status reporting and error handling as well. Now I just need someone to test this out and let me know if my guesses are correct! :)

Looking ahead, the UP-D898 series is a somewhat different beast, eschewing the old Sony comms format/protocol in favor of something wrapped in HP-PJL. It shouldn't be too hard to support, but someone's going to have to send me one first.

Happy printing!

Ongoing printer developments

It's been more than a year since I've posted anything about printers. Rest assured that progress continues whether or not I write anything about it. I always keep this page updated with the current state of affairs, but day-to-day changes tend to only be documented in my selphy_print git repository.

Goodnight, Moon..

January 21st, there was a total Lunar eclipse. I pulled out my Ukranian 500/5.6 mirror lens and tried to get some decent pictures, but there was a lot of haze in the upper atmosphere.

This was my favorite picture of the set:


In other news, I accidentally deleted the photos I took of the new year's sunrise, on West Palm Beach. No real loss, as it was an overcast horizon, but I got a really cool shot of the sun while driving home that I wanted to post.

I'm now a free agent...


Arm Deerfield Beach (nee Sunrise Micro Devices), April 2013 - December 1, 2018.

On October 30th, Arm informed us that they were shutting down not just our office but their entire wireless networking group. In about four more hours, I will be officially unemployed, along with over 40 of my nearly-former colleagues.

It is a gross understatement to say that this unceremonious scrapping of five and a half years of concerted effort comes as a dissapointment, but in the immortal words of Futurama's Hedonism Bot, "I regret nothing!"

Even though David Flynn's "Florida Adventure" did not ultmately acheive the commercial success Arm was looking for, we can still be proud of what we achieved. I personally learned a great deal and worked with many brilliant colleagues that I already miss. I hope our paths cross again.

....been there, done that, and got the commemorative poster.

So, what's next for Solomon Peachy? My experience at Arm has greatly expanded my skillset, and combined with a farily decent economy, I find myself in a position where I can afford to be picky and aim higher.

I'm angling for a role that I can perform (mostly) remotely, or at least closer to my Tick Farm, and ideally something that has me working on foundational Free/Open-Source Software. But even that is a wide swath, and in the mean time, I have a huge backlog of personal projects to work on, and maybe get in some long-overdue flying in the process!
