Hi All, Currently we are running on Koha v3.14 and have all of a sudden come across an issue with printing slips in the Circulations screens (particularly Checkout and Checkin). Previously we have never had an issue with printing slips from any browser that we use (normally Google Chrome and Apple Safari - both on Macs), but now all of a sudden when we click/select the print slip options either from a menu option or a checkin alert Koha will quickly appear and disappear the print preview window within a second with no print dialogue box appearing whatsoever. I have tried Circulation in Firefox and have found that it will print slips, but when it does print the slips they are the length of a standard A4 piece of paper at minimum, even though the slip(s) aren't even near half that in length. Does anyone know what may have happened here, or how I would go about resolving this issue, as Google Chrome is our preferred browser as it runs a lot faster and efficiently compared to what Firefox does. Many thanks in for your advice/assistance in advance and I await any responses. Kindest Regards, Joel Fitzgerald
