I've searched and not found a satisfactory solution to the problem of printing large images. I've tried the "poster" program on the command line and it won't produce the correct ps file for printing individual pages of pieces of a large image. kprinter uses this program, it's called when the poster option is turned on in the poster tab. It just won't work for me and I can't see any error codes to fix it with.
I've got this large schematic diagram in pdf format which I've extracted and converted into several formats trying to get it printed and half my hair is gone. Thanks.

There is a manual method as I mentioned in this thread. I don't know if using a mosaic plugin with gimp would take your printer's default margins into account.

Thanks, Junior Hacker. Okay, I tried this and some of the lines of the schematic don't match up, I cut it up into six pieces with Gimp, printed each piece and when I put it together the bottom three pieces seem larger, they just don't match up right.

I can imagine it is difficult to get things matched up with copy n paste in gimp.
What was the problem with the poster utility ( ftp://ftp.es.ele.tue.nl/pub/users/jos/poster/ ) ?

I am bored, and it is raining. Do you want to email me the schematic and I'll see if I can get poster to work for you?

Well, using the poster program, gv errors out when attempting to load the resulting ps file, I can't copy the message output, but the last line is something like "GNU Ghostscript 7.07: Unrecoverable Error, exit code 1".
So "poster" ain't working right for me, maybe I need to upgrade Ghostscript?
Emailing you the image sounds good, thanks.

OK. I've DL'd poster and I'll compile it.
You'll need to click my name at left, and send me an email. That way I get your address, can email you, then you can email me the schematic as an attachment. Complex handshake I know, but it means our addresses aren't on this board for the spambots to harvest.
Might be a good idea to send the ps file that ghostscript wouldn't read as well. I'll take a look at that too.

Okay, tredegar, thanks for the ftp link to the "poster" source, I downloaded, compiled and installed it after uninstall of a previous one and it works perfectly now ( I had downloaded the program from two other sites but neither one worked ). Ghostview loaded the resulting ps file and printed it fine the first time. Thanks so much, again.
I bought a schematic of a Fisher "Studio Standard" model CA-885 amplifier that was given to me not working and is well worth repairing, but I couldn't read the schematic on the monitor without a great deal of moving around and that just doesn't work with a diagram of this size.

Excellent! Time to get out the scissors & sticky tape & good luck with the repair job.
