Do you know about LPR / LPD printing? Can you setup a LPR/LPD to PDF printer server? (on a Mac or PC ideally) (No actual printer is involved). Can you configure yourself all the ports needed for you (yes you, on your side), in order for you to give an IP (your current IP), so that I can test by printing via LPR to it? And you send de PDF as a proof that is working?
There is really no programming involved. You just need to setup the parts, and if it works, the work and payment resides in you helping configure it afterward on my part. Please, first proof it works, before asking me to install anything and before sending me instruction.
Ideally, if you understand, send me just an IP number for me to print to it via LPR. If you can send me the test page I print to it as PDF, it means you understand what we are looking and the it is working.
Thanks and Good Luck!
