Hello,

It seems that samba does not like to load a printer from /etc/printcap when its name is greater than 15 characters.

 printcap name = /etc/printcap

The code seems to do just that:

 109                         if (strlen(p) <= MAXPRINTERLEN && *name == '\0' && !has_punctuation) {
 110                                 strlcpy(name, p, sizeof(name));
 111                                 continue;
 112                         }
 113 
 114                         if (!strchr_m(comment, ' ') &&
 115                             strlen(p) > strlen(comment)) {
 116                                 strlcpy(comment, p, sizeof(comment));
 117                                 continue;
 118                         }
https://git.samba.org/?p=samba.git;a=blob;f=source3/printing/print_standard.c;h=b5f1056b2e6f1a6e8bbe55d43676e01b1d0811ea;hb=b27c976e2e958998bb17f9b443de3962276bbd4e#l109

However, MAXPRINTERLEN at 15 is not the current reality. It should, at most, warn with something like "WARNING: You have some printer names that are longer than 15 characters. These may not be accessible to some older clients."

Could this check be simply removed?

Using "printcap name = cups" does not have this limitation.
