It really depends on how much and the type of copy you are trying to fit, however, I would recommend that you don’t try any of the substitution methods, keep it as much like as any other copy you want to be read, you can reduce the word spaces slightly, but anything else will reduce the usability. Try keeping it left aligned with the right ragged with as few hyphens as possible, if there is a lot (a page for example) use columns rather than a long measure. When you mention printer settings are you trying to print this using a laser printer? I have achieved fairly satisfactory results with both these faces at 5.5 on 6.5pts, but bear your audience in mind.

Gotham Condensed springs to mind. Read about it in use at large or small sizes here.

Since 2 out of 5 English letters are vowels, I recommend — after choosing the smallest font possible— modifying the a,e,i,o,u to sit on the top or go under the preceding letters. You will get something similar to Arabic Script. Worth Trying?!

very interesting

thank you very much!

Ascenders and descenders create a lot of empty space. Use all caps, or a unicase font, and you can subtract leading to get more lines in.

That objective for what, member ?

>Ascenders and descenders create a lot of empty space. Use all caps, or a unicase font, and you can subtract leading to get more lines in.

You need to expand leading when you are using AllCaps only…

In addition to Ligatures, Kerning and Swashing, my Uncompromising Arabic Font is also distinguished by Punctuation Marks like these:

Instead of doubling letters by repeating them, I suggest borrowing the dot of i or j to sit on or go under single letters?
Fortunately there is no English word with double j or ii save Hawaii?

Here are a bunch of words that contain ii:

aalii, alibiing, aquariist, arctiid, assagaiing, assegaaiing, assegaiing, bacchii, chivariing, congii, coniine, coraciiform, denarii, dochmii, dupondii, euphausiid, filariid, foliicolous, gastrocnemii, genii, gobiid, iiwi, iiwis, interradii, marconiing, medii, modii, nauplii, naupliiform, obiing, obiism, obiit, octonarii, perradii, piing, radii, reduviid, retiarii, sacroiliitis, safariing, sartorii, saturniid, senarii, septenarii, sextarii, shanghaiing, shiitake, skiing, splenii, stapedii, sylviine, taxiing, teiid, tholeiite, tholeiitic, torii, trapezii, triiodothyronine, turfskiing, waterskiing, wongiing, zombiism

And here are two that contain jj:

hajj, hajji

None of these are proper nouns, and they all appear in English-language dictionaries.
