Well, this is interesting. Last night I installed Gimp Print and Ghost Writer on the machine directly connected to the printer and my machine which shares the printer over the network. I attempted to follow directions to add our printer under the advanced tab in Print Center. I would get it all set up and then close the window and go back in to double check and none of the information would stick, in other words, the set up was blank. I also did not understand how to set up my computer since it was not directly connected. I gave up.
Until this morning, when I got your message. I checked the print area and it was still 17.21x11.5 under a Tabloid Extra setting under "Any Printer" in the page set up. Just for the hell of it, I switched the setting from Any Printer to our Epson 1270 and there were several different and new standard paper sizes to choose from. So I select 12x18, which comes out to be 17.88x12 actual print area. I try to print and everything comes out fine. I don't know how I got this to work. The Print Center on the computer that is directly connected to the printer shows the Epson 1270 under the tab marked Epson USB. But on my machine every tab is blank, yet the Epson 1270 magically is appearing as the printer in the print center.
Is that magic just Printer Sharing over the network. I will test this more through out the day. I guess I would like to know if any of this makes sense. Even though it printed correctly, I'm not sure that it all makes sense. Thanks for your time.
