HP Designjet T120 Printer and Linux

I got a HP T120 printer plotter a couple of days ago. This is a printer with a thermo-ink head, and the ability to print on 610mm rolls, for its quality and speed it is very budgetary.
After unpacking it and connecting to wifi, I started connecting.


First I checked what is in the Debian testing Cups, it turned out there was nothing similar there. It’s useful to look for a “driver”, on the HP website there is a link in the drivers with the name Linux, but the page is blank.

Having a bit of a chagrin, I decided to look at what he is capable of at all, connected ePrint, a fun feature, but the processing of tasks is very slow and you cannot change the parameters, it prints only in normal quality.

I started to think further, in a lot of useless information I fished out some pieces of information, thanks to which I realized that I could try to print via hpijs. After several attempts, I got to the working ppd from the hp deskjet 990C, it prints 4 sheets, the 1200dpi mode also works.
But this was not enough for me, I need the ability to print large formats. I fixed ppd by adding A2 and A1 formats to it, voila, he began to print on a roll in the desired formats.





UPD: ppd file, the same driver can be downloaded here HP T120 driver for Linux
UPD2: When resolving issues with printing in landscape mode, a bug was discovered that has not yet been resolved on bugs.scribus.net.
This is due to the fact that in postscript 3 you do not need to add 90 rotate on each page, when converting pstops ghostscript it does it itself, accordingly removing 4 lines from /scribus/pslib.cpp, we get stable landscape printing from scribus.
