Question Mark on Canon Selphy CP1200 Screen

Canon Selphy CP1200

I picked up a Canon Selphy CP1200 photo printer.

It’s a dye sublimation printer, meaning you have a roll of cellophane ribbon instead of ink. The 4×6 pictures it produces look pretty good.

There is a small variety of papers: 4×6 glossy photo, 4×6 postcard, and square stickers. I’ve only tried the photo paper.

The first photos I printed were from my smartphone, and that went well.

I haven’t figured out how to connect my MacBook via AirPrint. Probably boneheadedness on my part and Canon’s email support only parroted the instructions found elsewhere.

I’m using this machine to pass on Facebook photos to someone who doesn’t use a computer, and printing FB pictures from a USB thumbdrive was hit and miss for me. The Selphy is pretty particular about the format of the jpegs it prints; many photos showed question marks on the screen even though they contained thumbnails, and they wouldn’t print.

If you are also facing this problem, the easiest solution is to export the pictures from Photoshop or the open source version, Gimp.

If the photo has a color profile, Gimp will ask if you want to embed it. Click Convert to embed it.

When exporting jpg in Gimp, be sure to use the following options:

  • uncheck Optimize
  • uncheck Progressive
  • check Save thumbnail

These choices will come up after you select jpg and say save, yes replace.

Leave both EXIF and XMP info boxes check marked.

I’ve had no problems since following this process.

Cady Stroble!

Those who know tell me that you’ve withdrawn a house-size amount of money. Have you found a place? Have you stopped running?

My heart brims with hope.

Sigil: A Free Utility for Editing epub Files

I’m doing these epub posts bass-ackwards, but that’s no surprise to anyone who knows me.

So how did I correct the problems with my epub file reported by Pagina epub checker? How did I prepare the epub file in the first place?

Ladies and gentlemen, meet Sigil. If you google sigil you get this wonderful definition:

an inscribed or painted symbol considered to have magical power

But what I want you to do is to google download sigil and look for a reputable site from which to download the epub editor.

Once you have it installed, come back here . . .

Okay, so now you have Sigil.

See, an epub (or a mobi) is just a zip file of the content html file and all the support files. If you want to check this out, just change the suffix of any epub or mobi file to zip and check out the contents.

Sigil is a free Open Source epub editor that lets you edit the epub content xhtml files and any image files, including the cover, plus images within the content. It also lets you define both TOCs— the table of contents within the book pages and also the table of contents that lives behind the scenes in the epub collection of files.

Sigil guides you toward creating separate files for each of the chapters and guides you in creating the cover jpeg— you still need to supply an image of the right size.

You can load a validator into Sigil, but I used epubcheck (see previous post on validating epubs), which provides the file name and line number of any problematic code. You go into Sigil and fix the problem just like that: surgical strike.

See, an epub or Kindle is mainly html code, probably assisted by a css style sheet, which Sigil guides you toward.

If you’re building your own epub, you want Sigil.

And do you know about Kindle Previewer? It will convert an epub file to mobi, which is the Kindle format. And it will let you preview the mobi file in the various Kindle capabilities.

I think that covers it, but I’ll add anything if I think of it.

Validating ePubs

If you decide to distribute your epub through Smashwords, it will get validated, and Smashwords will not list your epub until it passes validation. But the errors they provide are of little help.

You want to run your epub file through a utility called epubcheck to validate it and receive error feedback that’s helpful. There’s an online version available at

IDPF’s EPUB Validator

You can run a version on your desktop by grabbing the Open Source utility epubcheck.jar and installing Java on your computer.

GitHub is a source for the zip file and has a wiki on epubcheck:

For the .zip file:

The main GitHub page for epubcheck:

The wiki starts here:

Okay, so now you’ve got epubcheck.jar. You need Java to run it on your linux or windows or macintosh computer. You’re probably best off googling java download to get the most recent info for your situation.

For Windows 10, the FAQ:

For Macintosh Sierra, the FAQ:

If you’re running Linux, you’re too cool to need my help.

Okay so now you’ve installed Java on your computer.

This gives you the ability to run a .jar file from a command line.

So Windows people bring up the Run command line and enter something like:

java -jar C:/epubcheck/epubcheck.jar C:/test/name of the .epub file

Mac users go into the Utilities folder in Applications, launch Terminal, and . . .

I’ll tell ya. I don’t know what we Mac people do at this point, ’cause this is when I went to the GUI page of the epubcheck wiki:

where I learned about Pagina epub checker:

And here is where I’m at, about to fix the nine errors in my epub file.

What errors? My epub is now valid.

Pagina epub checker gives you the file name and line number of each error, making it easy peasy to fix the problems.

I now have valid epub and mobi files on this site.

epub passed the Smashwords validator

Religion ∩ Civil Law = ∅

Religion and Civil Law do not intersect

I think some people conflate the spheres of religion and civil law. They are two separate realms, just as religion and science are— and we have many religious scientists of faith.

Jesus’ declaration that marriage is between a man and a woman lives in the realm of religion.
The laws giving gays the right to civil marriage live in the separate realm of civil law and are based on the concept of not excluding one class of citizens from the rights and benefits of civil law.

A president who supports gay marriage is not turning his back on his Christian faith. He is acting in accordance with the First Amendment separation of religion and civil law.

Let me add that we still have prayer in school—we just don’t have someone telling us what to pray, because we don’t all pray with the same words.

I prayed in school many times and was never arrested for it.

And while I’m on this soapbox:

You can still say Merry Christmas!

Those of us who wish people Happy Holidays are honoring the different beliefs that don’t all celebrate Christmas. We’re being inclusive, not exclusive.
