First, the temptation is often to use masking tape. After all, we use it to mask when painting, so it should work well, yes? NO! — DON'T! While you'd think it'd work just fine, it's only meant to be on for a few hours to a few days. Too long and it leaves glue behind and other chemicals behind.
I've never used electrical tape for this, but as an electrical engineer, I have used a whole lot of it for connections over many years and it does leave glue and other residue if left on too long. Unfortunately, I don't know what too long is and perhaps some other member with experience using it could chime in. However,, you've still got several additional options.
Historically, we've used art tape on analog desks. This is the stuff used by artists and framers to hold prints to matting and such. It's not cheap, but it's acid-free and you can leave a scribble strip on a mixer for years and it'll still come off clean — well, at least it always has for me and many others. A roll from Amazon is currently $12.95 for 180foot 3/4 roll w/Prime. It's white, non-glare, and takes writing well:

A friend likes this "economy" version of artists tape and claims it works well. I haven't tried it:

These days, there is even an official "mixer tape" you can buy. Of course, it's even a little more expensive than artist tape, but hey, it's "specifically designed" for mixer scribble strips! That and another 4 bucks and you can get a cup of coffee at Starbucks. It's made by Hosa and you can get it for $14.50 for 180foot 3/4 roll w/Prime:

Here's Hosa's Webpage with a little more info (very little):

Finally, I don't know how it works with other DAWs, but with Pro Tools using the Mackie HUI protocol, the Control tab on the Remote screen displays 3 lines of 8 channels each. Whatever label you assign to each mixer channel in PT (e.g. kick, snare, hihat, etc.) will be displayed on the aforementioned screen. So, while it's not as good as an actual electronic strip for each channel as some mixers provide, it's probably the next best thing because you assign a name to each channel and that same name displays both in your DAW and on the Remote mixer display.
So there you are.
