Then go to http://localhost:631 with your web browser and follow the steps to "Add Printer". It will ask you to log in to add a printer. Log in as root, then finish the steps. Once you're done, you should be able to print.
If that doesn't work, you may also need to add HPLIP's dependencies separately. There are currently no packages for CUPS DDK,

mdev hacks for USB printers
By default USB printer with mdev would have ownership root:root and permission 0660. As cupsd would try to open a libusb-based printer as lp user, it won't have permission to use the device in /dev/bus/usb.
First let's get some info about our USB printer.
# lsusb | grep Printer Bus 002 Device 011: ID 04b8:0007 Seiko Epson Corp. Printer
Now use 002 and 011 for next query.
# apk add eudev # udevadm info -p $(udevadm info -q path -n /dev/bus/usb/002/011) P: /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1 N: bus/usb/002/011 E: BUSNUM=002 E: DEVNAME=/dev/bus/usb/002/011 E: DEVNUM=011 E: DEVPATH=/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1 E: DEVTYPE=usb_device E: DRIVER=usb E: MAJOR=189 E: MINOR=138 E: PRODUCT=4b8/7/100 E: SUBSYSTEM=usb E: TYPE=0/0/0
What is important for us is 'PRODUCT'.
# cat >> /etc/mdev.conf <<EOF SUBSYSTEM=usb;PRODUCT=4b8/7/100;.* root:lp 660 */lib/mdev/usbdev EOF
Unplug USB cable and plug again, now USB printer device in /dev/bus/usb/ will have valid ownership and permissions.
# ls -l /dev/bus/usb/002/011 crw-rw---- 1 root lp 189, 138 Apr 14 21:19 /dev/bus/usb/002/011
CUPS will be able now to use libusb to discover local USB printer.
Additionally, in a desktop environment you could proceed as follows.
Check whether root and the user's username (yourusername) are already members of the
lpadmin groups. Note: yourusername can be added to the
lpadmin group if he/she will administer the CUPS system.
$ id root uid=0(root) gid=0(root) groups=0(root),0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),11(floppy),20(dialout),26(tape),27(video) $ id yourusername uid=1000(yourusername) gid=1000(yourusername) groups=1000(yourusername),6(disk),10(wheel),18(audio),19(cdrom),20(dialout),27(video),100(users),1001(plugdev)
If not, add them:
$ sudo adduser root lp $ sudo adduser root lpadmin $ sudo adduser yourusername lp $ sudo adduser yourusername lpadmin
Start CUPS (cupsd) and make it persist between boots; then reboot:
$ sudo rc-service cupsd start $ sudo rc-update add cupsd $ sudo reboot
Credit to ArchWiki's excellent CUPS page for guidance with the following basic steps. Locate your printer
With your printer connected and powered on, determine the URI for your printer. Depending on whether the connection is via usb or parallel ports, the URI will carry a
$ lpinfo -v # network lpd network socket network beh file cups-brf:/ direct usb://HP/LaserJet%202200 network ipp network ipps network https network http direct hp
In the example above, the URI is
Find a .ppd or .ppd.gz driver.
If your printer supports IPP Everywhere --most recent models do-- see the driverless command in cups-filters:
$ driverless ipp_uri > printer.ppd
or just pass -m everywhere to lpadmin.}}
Otherwise, you could list all the drivers available by running
lpinfo -m and then searching through the results to find a .ppd or .ppd.gz specific to your printer. A quick solution is to use the
--make-and-model flag and the
grep function in order to filter the results by plugging in your printer's make, model and series in this fashion:
$ lpinfo --make-and-model "make_and_model_names" -m | grep -i printer_series
For example, type:
$ lpinfo --make-and-model "HP LaserJet" -m | grep -i 2200
Out of the results obtained, you might select the following .ppd driver:
If required, further drivers can be obtained by installing gutenprint, and running the
lpinfo search again. These may not specify .ppd names.
$ sudo apk add gutenprint gutenprint-doc
Configure a queue
Create a queue using a queue_name of your choice. Your selected printer's name is an obvious choice, but do not employ spaces. You will also need to be root or use
sudo instead, and you will also need to plug in the URI and the .ppd driver:
# lpadmin -p queue_name -E -v "uri" -m driver
With this example, you could set as follows, but there are other solutions.
# lpadmin -p HP_LaserJet_2200 -E -v "usb://HP/LaserJet%202200" -m drv:///hp/hpcups.drv/hp-laserjet_2200-pcl3.ppd
This printer queue could be set as default:
# lpoptions -d HP_LaserJet_2200
Printer settings can typically be set in your GUI application's Print menu or by examining the CUPS lpoptions page. If you have a single queue, the setting options available (such as page type, duplex, etc.) for your queue can simply be listed by using the -l flag. Asterisks(*) indicate current settings:
# lpoptions -l PageSize/Media Size: Card3x5 Hagaki Photo4x6 A6 Photo5x7 Card5x8 Oufuku A5 B5 JB5 Executive 16k Letter *A4 ExecutiveJIS FLSA Legal EnvA2 EnvC6 EnvChou4 EnvMonarch EnvDL Env10 EnvChou3 EnvC5 EnvB5 Custom.WIDTHxHEIGHT Duplex/Double-Sided Printing: DuplexNoTumble DuplexTumble *None InputSlot/Media Source: *Auto PhotoTray Upper Lower Envelope LargeCapacity Manual MPTray ColorModel/Output Mode: *Gray MediaType/Media Type: *Plain OutputMode/Print Quality: *Normal Draft Best OptionDuplex/Duplexer Installed: *False True
If there is only one queue, options can be set by simply using -o flags for each setting:
