Some background for FedEx you may (or may not) find helpful. The
Business::Fedex::DirectConnect my business partner wrote can return EPL code
instead of a raster PNG or GIF image.
EPL (Eltron Printer Language) is an ASCII-based code when piped to any
Zebra printer supporting EPL (most do including yours) will quickly spit out a
label. In a recent application, we simply opened a printer handle using lpd
and output the ASCII code. Here is some psudocode:
my $t = Business::FedEx::DirectConnect->new();
open PRINTERHANDLE, "| lp -d zebra" || die "Can't open printer!";
print PRINTERHANDLE $t->label;
This method does away with TIFFs, GIFs, PNGs or any other raster
images. And I
am pretty sure UPS's API also supports EPL/ZPL as well.
Hope this helps.
