Versiegeschiedenis van el-Print

You can now choose which websites are allowed to print.

Until this version el-Print accepted a print job from any website open in the browser on the same machine. The program listens on your own computer, but it is the browser that makes the connection, so that offered no protection: a page you happened to visit could send jobs to your printer. Settings now has a list of the addresses permitted to print — put your shop's address there.

The list starts empty, which behaves exactly as before and keeps existing setups working. Filling it in is the fix, and the program writes a reminder to its log every time it accepts a connection while the list is empty.

Also fixed:

A configuration file damaged by a power cut or a full disk stopped the program from starting at all, with no window and no message. The unreadable file is now set aside and a fresh one written next to it.

Printing to a network printer could freeze for minutes and then report a failure for a label that had already come out. The job is now finished when the data reaches the printer.

A queue of labels shared a single ten-second budget, so a long batch — or one slow printer — stopped part-way through and the rest was never printed. Each job now has its own.

Turning autostart off did not stick: the program switched it back on the next time it started.

The log file grew without limit. It is now rotated.

Timeouts, size and rate limits and log retention have moved into config.json, so a slow printer or an unusually large job can be accommodated without waiting for a release. An existing config.json keeps working unchanged.

The application has a new icon.

The licence is now a separate file instead of being built into the program.

Download el-Print once, for whichever system you use, and load the licence file you get with your purchase — the program reads it at startup and tells you who it belongs to and how long it runs. A renewal is a new file; nothing has to be reinstalled.

Without a licence the program still starts, and everything except printing works.

New: a test page. The Printers section has a button that prints a fixed page — a document, or a ZPL, EPL or TSPL label — without needing a licence. If it comes out, el-Print can drive your printer, and anything that goes wrong afterwards is somewhere else. Useful before buying, and the first thing to try when a print does not arrive.

macOS builds are now produced on a Mac. The previous macOS downloads could crash on launch on some machines; those builds have been replaced.

Updated to Fyne 2.8, with the image decoding libraries updated to close known vulnerabilities.
