Now libprint supports the following type of settings: A list of values visualized as a combo box, a boolean flag visualized as a check box and a value in a range of values visualized as a slider.įigure 2 shows the job setup dialog. For the missing settings libprint had to be extended to show them in the job setup dialog and to persist them in the job settings. Some of these settings can be mapped to existing settings provided by libprint. Gutenprint contains a meta model for the available settings of a printer model. The page setup dialog in Figure 1 shows the values for paper size and resolution from Gutenprint. For example whether a printer is a color printer and the available paper sizes (Letter, A4. The setup dialogs provide a fixed set of settings whose value ranges are configurable to match specific printer drivers. The printer driver then converts the bitmap bands to a stream of data in a format that is understood by each printer. It performs the rendering of the page as a sequence of bitmap bands. It provides the user interface for the page setup dialog, the print job setup dialog and a preview window. This framework makes it very easy to add a new printer driver to Haiku. Exceptions are the Preview and the PDF printer driver. Libprint, the printer driver framework, is used by native printer drivers such as Canon LIPS 3 and 4, HP PCL5 and PCL6, and Adobe PostScript. This article describes Gutenprint and the effort to port it to Haiku.Įxtending the Haiku printer driver framework Gutenprint was recently ported to Haiku, both increasing its printing capabilities, as well as extending its supported printer models. Gutenprint currently supports over 700 printer models. With modern printers usually being driverless IPP printers, classic printer drivers, installed under CUPS by its web interface or a printer setup tool, are deprecated and replaced by Printer Applications (for the non-driverless legacy and specialty printers) which emulate driverless IPP printers as this one.Gutenprint is a suite of printer drivers that can be used with UNIX and Linux print spooling systems, such as CUPS (Common UNIX Printing System), lpr, LPRng, and others. In the future, there will be utilities to easily find non-driverless printers and find the correct Printer Application for them. You find it with your browser under Note that currently printers have to get added via the web interface to use them. Like on a physical network printer there is a web interface for administration, here especially also for adding and configuring printers. This Printer Application emulates a driverless IPP network printer (IPP Everywhere) for each physical printer set up with it, so your computer's printing environment discovers it automatically and makes your printer(s) available for printing. As soon as the Gutenprint project provides a native Printer Application, this Printer Application retro-fitting the CUPS driver will get discontinued. Especially they should create a native Printer Application, meaning that it does not use PPDs, CUPS filters, and CUPS backends internally. Note: Gutenprint is an actively maintained project, therefore it would also be the correct way if Gutenprint gets turned into a Printer Application by its maintainers, or at least this be offered as an alternative to the classic CUPS driver. ) and has made many user's printers work and with this Printer Application these printers will continue to work in environments where only Printer Applications (and no classic printer driver packages) are supported. Gutenprint already ships for many years with most common Linux distributions (Ubuntu, Debian, Fedora, SUSE. Note though that as a Printer Application is an emulation of a driverless IPP printer, using the printer's own driverless IPP functionality is recommended. Some of these printers are probably also driverless IPP printers, but you can still use this Printer Application then as perhaps you could get better output quality. In addition it provides generic support for the different PCL flavors, everything which is supported by the Gutenprint CUPS Raster driver ( ). It supports more than 3000 different printer models, especially inkjet printers from Epson and Canon, dye-sublimation photo printers, PCL 4/5c/e laser printers, but also some other printers. If you want to use a printer which is not a modern driverless IPP (AirPrint, Mopria, IPP Everywhere, Wi-Fi Direct Print, prints from smartphones) printer (then you do not need any Printer Application) and/or want to print in very high quality with many adjustable options, for example photos or fine art, then this is the right Printer Application for you. if you have more than one Printer Application installed), click "Add Printer". Usage/Setup: Install this Snap, go to (or to.
