printing in series

[carlo]

hi all
i need help to understand what's going on

for work i have to print sweveral letter bag (sort of 22x11 cm format)
till two weeks ago everything worked like a chamr
today every time i launch a print series i get only the first parchment pritned properly, as for other ones seems like printer is printing on an A4 sheet or rotates, but since paper isn't that big it's only making a mess

i use sparky, libreoffice and hplip, so i'm not sure it might be libreoffice, cups, hplip or printer or something else
please help cause it's urgent
