Printing your slides two-up

Printing your slides two-up is useful both for previewing slides and for making hard copies to distribute or for proofreading. One way to print your slides two-up is to include the Øarticle style option. This is described further below. Another way is to include the command
$\begin{MD} \twoup[n] \end{MD}$
in the preamble. This inputs "2up.tex", which contains generic macros for two-up printing, and sets the parameters to values that are likely to work. Including the optional argument "[<n>]" increases the two-up magnification by n magsteps. n can be a positive or negative integer. If you are not able to get the right layout, then include the Ø2up style option, read the documentation of "2up.tex", and set the parameters yourself, rather than using the command. The øarticle style option is also called the article format (as opposed to the slides format). In the article format without the øportrait option, the slides are centered horizontally and vertically, two to a page (if they fit—landscape slides do fit by default). With the portrait option, the slides are printed side-by-side, two to a page. In the øarticle format, you can mix landscape and portrait slides with different orientations, but this does not work well with the øportrait option. You can change the article format's magnification with
$\begin{MD} \articlemag{n} \end{MD}$
This command works like the "" command (page

). The default is

  \articlemag{0}

Increase the article magnification if the slides look too lonely; decrease it if they are not coming out two-up. The size of the slides depends on the difference between the magnifications in the slides and article format. E.g., since the default slides magnification is 4 magsteps, the slides are scaled down in the article format by 4 magsteps. When you change the slides magnification with , you also have to change the article magnification with by the same amount if you want the size of the slides in the article format to remain the same. However, when the article magnification in magsteps is negative , you will be using non-standard font magnifications (which will produce terrible results if you cannot generate the needed fonts—see Appendix

for advice). Whether or not landscape slides (or rotated portrait slides) come out two-up in the article format without the øportrait option depends on (i) the difference between the slides and article magnification, (ii) the values of and (iii) the size of the slide frame, and (iv) the article format's page parameters. With the default values of (ii)–(iv), the slides will still come out two-up if you change the difference between the slides and article magnification to 3 (e.g., increase the value of by 1). Try this if you want the slides to be larger. If you use the øarticle option and the command, then your slides should be printed four-up! You will notice labels on the side or bottom of each slide in the øarticle format. The command
$\begin{MD} \slidestyle{style} \end{MD}$
determines where these labels go. There are three predefined slide styles:

empty: No captions or labels are used.
left: The labels go on the left of each slide (the default when the øportrait option is not used).
bottom: The labels go on the bottom (the default with the øportrait option).

The label you get is the value of . The default definition of is
