Hello, I have a document that includes some grids (drawn with \grid) as well as alphanumeric information (letters and numbers) which contents (the info, not the grids) I modify every year and then print it out. I've been using it without any problem for a few (maybe 4 or 5) years but, this time, only the grid showed up on the printout, but none of the letters or numbers would, using the same printer I used every time before. I always copy the PDF file into a USB stick that I bring to the (departamental) printer, plug it in the printer and directly print from it. I tried printing the same file (from the same USB drive) into a different printer, this time connected to a computer, and sending the file from it, which worked just fine. My guess is that the first printer in missing the font the document uses, whereas the second printer received the font from the computer (Devuan Linux), which has the appropriate font. Could that be correct? In all previous ocasions I used the version of ConTeXt included in Texlive on Devuan, but a few months ago I decided to install ConTeXt using the official distribution instead. Could that explain the change in behaviour I'm seeing? Could it be that the previous versions I used somehow embeded the fonts into the PDF file but the current one doesn't? And, if that's really the case, how could I force the font to be included into the PDF file? I remember I read something like that a very long time ago (probably about LaTeX, not ConTeXt), but I haven't found how to do it now in a few searches on the documentation. Thak you for any help or advice. Cheers, Ángel
