Open Source Python Print Servers

Passermark is a free, open-source PDF viewer, print tool and prepress toolbox for Windows and Linux. It is developed alongside real daily prepress work and uses the printer drivers already installed on your system (CUPS on Linux, Windows drivers) with all their options — including finishers. View and print: PDFs, images (including HEIC and SVG) and Office files via LibreOffice. Imposition: fit/scale, N-up, poster tiling, step and repeat, booklets as saddle stitch, grouped signatures or stacked single sheets with creep, marks and sheet overview. Plan and poster printing on roll devices: rolls are read from the device (IPP/SNMP) with automatic or fixed roll choice, live running-metre calculation with low-roll warning, overspill strips, cut and fold marks, panel splitting for anything wider than the roll.
