Chromebooks on the Dev Channel seem to be getting a lot of love lately, as version 56 of the Dev Channel for Chromebooks has just received the ability to scale the size of documents or files in the printing options. This is in addition to four more Chromebooks gaining access to the Play Store app through the Dev Channel as of yesterday. When it comes to Print Scaling, since this is only available in the Dev Channel right now users would have to swap their Chromebook over to the Dev Channel to access it. That is, if they even need it in the first place.
If you're the type that does need or at least prefer to have print scaling as an option in the event that you do need it at some point, then changing over to the Dev Channel is rather easy to do. To access it, you simply need to open up the Chromebook's settings, which you can get to by clicking on the area where you see your profile photo in the bottom right corner of the screen. Once the settings window pops up you'll need to click on the link towards the top of it that says "About Chrome OS" and then click on More Info. At this point you should see the change channel button with options to move between Stable, Beta, and Dev.
It is worth noting that simply moving to the Dev Channel won't enable print scaling and you'll still need to take a couple of extra steps. First, open up Chrome and navigate to chrome://flags. From here you can either scroll to find the print scaling option and then click to enable it, or you can make things a little bit quicker by searching for print scaling after holding down the Ctrl and F buttons on the keyboard to bring up the search shortcut. Since this is a Dev Channel option right now, it's likely that it will have to move through to the Beta Channel before it makes its way over to the Stable version of Chrome OS, if Google decides to make Print Scaling a stable option at all. For now, you can at least access it in some form.
