Hello,
it seems a rather sparse question, but I've found several occurences of the
same problem, only not directly bound to PDFBox as it is mainly a Java Printing
framework problem, but I'm looking for a workaround.
I'm generating documents using Freemarker templates + FlyingSaucer library (template -> HTML
-> PDF). That part works well, producing desired documents with any requested custom
"paper" formats.
Adobe AcrobatReader displays them correctly and it is even capable of printing
them to a label printer via Windows print drivers (Zebra thermal printer, a
Chineese 4Barcode thermal printer or any standard Windows printer).
I'm using PDFBox (currently 3.0.2, but it is probably a problem since dark
ages) to get PDFPageable to be printed on a HW printer (or a Windows virtual
printer or whatever else, it really doesn't matter).
And there comes the problem with Java printing framework - it doesn't accept MediaSize with width > height. I'm not talking about
printing "landscape" as on most printers (taking the paper with the narrower edge first and rotating the image). I'm printing
on labels on a long roll, so I can't feed them rotated. Everything works perfectly with "portrait" format media (e.g. 10x15cm
labels), but when it comes to "landscape" fed media (40x10mm, 50x20mm...), I'm out of luck as Java framework
"fixes" page format to nearest "portrait" oriented format with borders, silently ignoring the exception thrown in
the MediaSize print attribute constructor (complaining about the W>H). The same happens when using the PDFBox-app.jar with print
command (I'm printing almost the same way as the PDFBox-app does, only loading the generated PDF directly via a memory buffer).
I know that it is a Java framework limitation, question is if there is a known workaround
for that. I can't make the media "higher" as it wastes labels (and in case of
e.g. RFID tag labels it gets very expensive).
Attached is a test "label.pdf" PDF (40x10mm) that prints badly from Java (even on "PrintToPDF"
printer or any standard printer, no need for a label printer to test) - shifted down and left by a default A10 paper
border. "label_result.pdf" is an attempt to print similar label (40x20) to a windows "Print to PDF"
printer. Printing the same PDF from AcrobatReader works perfectly, even directly to the label printer.
Thanks, Jakub
