Thanks for the suggestion, I tried some things out.
- In Chrome (My default browser) there was not a option to change the layout (BTW - That's a weird choice Chrome developers). It did have an option for local printer interface and here I could change it; except, printing in either landscape or portrait yielded the same results of a landscape looking printout with 8-cards.
- In Edge I had the option for both layouts and portrait, after changing margins to "narrow" could only do 6-cards unless I shrunk the cards down to 75%(next highest zoom option - again weird) and got 12-cards. See attachment
- In IE it brought up the local printer interface immediately and could not change the margins and in portrait only got 4-cards. Then when Not using your print button IE brought up the browsers print interface and I took the margins down to .166 on all sides and went from 100% to 95%(net highest zoom option) and got 9-cards!
Success! - In Firefox - without using your print button - I could take the margins down to .1 on all sides and by bringing the zoom to a custom level of 99%. I got 9-cards in portrait, Huzzah!
Final thoughts.
- First, Thank You, it works as you said with some extra effort and/or workaround on the user's part. I will excitedly be using your print proxy feature on Deckstats.net
- Last, It seems that unless we use Narrow margins even landscape has issues printing 8-cards consistently across browsers. For portrait, printing at 100% seems impossible unless Deckstats.net can reduce the white space between rows of card images.
