The emission of hydrogen lines and continua from solar prominences is investigated using a set of 140 simple models, covering the range of physical conditions usually assumed for these objects. These models are plane-parallel, isobaric and isothermal. The computations have been carried out using a 20 level plus continuum hydrogen atom, and taking into account the effects of partial frequency redistribution in the Lyman-alpha and beta lines. The aim of these computations is twofold: firstly, to describe the variations of hydrogen lines and continua emitted by prominences when physical conditions vary. Secondly, to provide observers with some diagnostic tool to interpret data such as intensity ratios, line widths, etc... The results of computations are given as mixed table-figure panels, each of them corresponding to a given model and summarizing the associated physical parameters and the principal features of the emitted hydrogen spectrum. Finally, for some specific parameters (or couple of parameters), we present figures illustrating the variations of these quantities across the whole set of models.
