Title: pretty strange: can not read Paper wallet print outs made by bitaddress
Post by: BNO on September 09, 2015, 03:21:12 PM
I printed out some Paperwallets, while i was online on bitaddress.com - They looked perfect.
Of course this is not how you should do it. So i downloaded the Website, opened a VM tried to print 7 Keys. At first it looked good, but when i lookded closer i saw that the 4th key had several letters in the middle very bad to read.  The 3rd key had some hard to read to. O.K. i thought one time error try again. Same again. Its always something with the 3rd and 4th key.After 3h now and 50-70 pages printed i now know that:

  • It is not the printer. Its Samsungs laser printer, in case you are interested. I opened it cleaned it - no change.
  • When i convert the website to an pdf - the pdf on computer screen already has the problem when i print it, it has the problem too
[it doesn't matter whether i print this from my PC (win7, firefox by the way), or a Vmwareplayer VM it is perfect when i'm connected to Internet and on the site, but it doesn't work from the file running on machine without Internet
[/list]

How can that bee that the printout is perfect with Internet, but always errors when running without internet on my machine ???
Please help i'm getting gray hair over this...

First of all,

(1) What version history of Bitaddress.org are you using? (You can find it on the bottom right.)
(2) Can you do some test generations and provide pictures of what your screen shows,
 and then what your printouts show? (Obviously, do not place btc into these test address.)

I am interested in what you are saying and whether it is a true concern or just a printing anomaly.

Thanks for taking the time to communicate your observation.  It actually is quite interesting.  I won't/cannot produce any hypothesis or suggests, but I hope you keep us informed on this thread.  I will say that real-time font server distributions probably do have an analytical component which is not commonly suspected by end users if that is a factor in the issues you are having.

Hi,
hosting pics can't do right now - sorry for that. I'm not a webdesigner, but it has clearly something to do with css/displaying page or fonts in browser.
I was using the latest version (2.9.11) I opened the page in three different browsers (Firefox 40.0.3, Opera 31.0 and an very old Internet Explorer 9.0 because i have it in VM and never go to Internet with that vm)

It looked always different (all the descriptions here are for OFFLINE use of the page):

Firefox: mostly perfect, layout of page perfect, but 3rd and 4th key had some letters which were hard to read. Rest of Keys, QR-codes and so on perfect.
Opera: Layout perfect, but heavy problems with the letters. Something with the embedding of the font has clearly gone wrong.
I.E.: total broken page Layout so couldn't use it.

So my quickfix for this was: to print it out in firefox  and c&p it in notepad and print that as a second piece of paper. This is very secure now - have everything twice and this is what i would recommend for anybody you has some letters not looking wright on his printout.
