дело в чём-то ещё...

PARPORT_SERIAL это

--- PC-style hardware                                                                                                              <*>   Multi-IO cards (parallel and serial)

$ lspci -v | grep -A 11 Parallel 
03:00.2 Parallel controller: MosChip Semiconductor Technology Ltd. PCIe 9912 Multi-I/O Controller (prog-if 03 [IEEE1284])
	Subsystem: Device a000:2000
	Flags: bus master, fast devsel, latency 0, IRQ 16
	I/O ports at b200 [size=8]
	I/O ports at b300 [size=8]
	Memory at f8104000 (32-bit, non-prefetchable) [size=4K]
	Memory at f8105000 (32-bit, non-prefetchable) [size=4K]
	Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [78] Power Management version 3
	Capabilities: [80] Express Legacy Endpoint, MSI 00
	Capabilities: [100] Advanced Error Reporting
	Kernel driver in use: parport_serial

То есть, модуль к PCIe-карте есть и загружен (вкомпилирован).

Пакет cups тоже установлен

# emerge -pv cups

These are the packages that would be merged, in order:

и процесс запущен:

$ ps -A|grep cupsd
   5212 ?        00:04:04 cupsd

Вот так ещё можно:

# systemctl status cups.service

Конфиг дефолтовый:

# grep -A 2 listen /etc/cups/cupsd.conf
# Only listen for connections from the local machine.
Listen 127.0.0.1:631
Listen /run/cups/cups.sock

Файрволла вроде бы нет:

# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

В строке браузера ввожу http://127.0.0.1:631

и не коннектится!
