TPS (Technical Print Service) InkJet 2600DN, page size A3

[Marco Zorcic]

On our workstations, PA-RISC/HP-UX 11.00, we use for applications like dtpad or dtmail TPS for printing.
Printer HP InkJet 2600DN has tray1 for A4 and tray2 for A3 this printer has a duplex unit too.

"SAM->Printers and Plotters->HP JetDirect" used for defining queue "bj2600_C129" which uses model script net_hp2600. Printing using command "lp" works.

Stop/Start Xprint

dtpad->File->Print->Print Setup->More Printers
shows a list of printers and after selection of:
bj2600_C129@becad04:1 InkJet2600 in room C129
in "Setup" is shown:
Printed sides: "Simplex, Duplex, Tumble"
Page Size: "#10 Envelope, Executive, ISO A4, ISO Designated Long, Legal, Letter"

=> But no A3 !!!

Button "Loaded in Printer" isn"t selectable.
Tray is in grey, nothing is offered.

I would like to understand how TPS negotiates with printers and how to enable features for new printers.
