Comment:
When the printer spooler folder is created the print_server is able to
load the BeOS R5 printer driver add-on and then calls the function
add_printer(spool_folder_name). In error case the function should return
NULL, and this is what happens no in Haiku. I have now idea why.
BTW if the print_server ignores that error and creates the printer anyway.
It seems that it can be used. I could print from StyledEdit to a file
without any issues.
I am quite sure that the problem is not caused by bugs in the print_server
or Printers preflet, because I have tested it on BeOS R5 with the Haiku
print_server and preflet and it was not a problem to create a printer. The
tested version is older than what's in Haiku, but the relevant parts for
this have not changed, as far as I can tell.
For now I won't investigate any further. Someone with the proper
disassembly experience could try to debug the function add_printer of the
"HP PCL3 LaserJet Compatible" and see what causes the trouble.
Ithamar, I have assigned the ticket to you. Feel free to reassign it to
me, if you don't want to look into it.
