Hi Zdenek, Regarding packaging pappl-retrofit and printer applications, looking at the pappl-retrofit based snaps from Till Kamppeter, I suspect the existing Fedora pappl package might need to be modified. For example, extract from ps-printer-app's snapcraft.yaml file which modifies pappl's default build settings: https://github.com/OpenPrinting/ps-printer-app/blob/master/snap/snapcraft.yaml pappl: ... override-build: | set -eux # Raise the supported number of vendor-specific options/attributes in # PAPPL to 256, as the original 32 can be too small for some busy PPD # files perl -p -i -e 's/(define\s+PAPPL_MAX_VENDOR\s+)32/\1 256/' pappl/printer.h # De-activate log-rotating. It does not work with the forked processes # of the filters perl -p -i -e 's/(system->logmaxsize\s+=).*/\1 0;/' pappl/system.c # As we do not use PAPPL's own backends but the CUPS backends using the # "cups" device scheme of pappl-retrofit, we let the manual "Network # Printer" device on the "Add Printer" page of the web interface use a # "cups:socket://..." URI instead of simply "socket://..." perl -p -i -e 's/(httpAssembleURI\(.*?)"socket"(.*?\))/\1"cups:socket"\2/' pappl/system-webif.c # PAPPL's build system does not insert the LDFLAGS when linking. # Patching Makedefs.in to fix this perl -p -i -e 's/^(\s*DSOFLAGS\s*=\s*\S*\s+)/\1\$\(LDFLAGS\) /' Makedefs.in Cheers, Doug -----Original Message----- From: Zdenek Dohnal <zdohnal@xxxxxxxxxx> Sent: Thursday, May 18, 2023 4:26 AM To: Development discussions related to Fedora <devel@xxxxxxxxxxxxxxxxxxxxxxx> Subject: PWG+OpenPrinting meetup 2023 Hi all, I've joined annual PWG+OpenPrinting virtual meetup where the news and statuses from the current printing development are discussed. The main points are: - cups-filters 2.0 betas and release candidates are released and present in Fedora 38 - since new cups-filters are in Fedora 38, nothing stands in the way of packaging pappl-retrofit and printer applications based on it into Fedora as RPMs - any volunteers are welcome! - CUPS 2.4.x, CUPS 2.5 and CUPS 3.0 are delayed: - 2.4.x - there are several regressions I haven't able to tackle yet, but I hope there is a new version in a month - 2.5 - OAuth support took lot of time to implement - 3.0 - libcups (its version 3.0) has a beta which developers which uses libcups 2.0 can compile and link their applications and see what changed between major release - GTK (its version 4) has merged support for Common Print Dialog Backends - universal print dialog, which can work not only with cups, but with other possible backends (like google cloud print) - WIP on Printer Setup Tool for GNOME Control Center - full support for driverless printers and printers via printer applications The full report is attached.
