PDF::API2 is 'The Next Generation' of Text::PDF::API, a Perl module-chain that facilitates the creation and modification of PDF files. It features support for the 14 base PDF Core Fonts, TrueType fonts, and Adobe-Type1, with unicode mappings, embedding of bitmap images, compression via zlib, and a rich object-oriented API.
LPRng is the Next Generation in LPR software. It supports the standard bsd lpr commands and also supports an System V interface. Other features include lightweight lpr, lpc, and lprm programs, dynamic redirection of print queues, automatic job holding, highly verbose diagnostics, multiple printers serving a single queue, client programs do not need to run SUID root, greatly enhanced security checks and a greatly improved permission and authorization mechanism. The default configuration provides a simple BSD LPR interface, but there are options to modify a wide variety of operational facilities. The companion IFHP print filter can interface to a wide variety of printers, from the latest network based high speed to vintage legacy printers.
