Introduction
In recent years, photo printing devices have become widely available leading to widespread adoption of
photo printing. Digital photo printing devices usually produce photoprints in short time.
The existing international standard (ISO/IEC 24734) for measuring printing productivity mainly
addresses a method for measuring business documents. These documents may be multiple copies and
consist of mixed content of text and graphics, on 8,5” × 11”, A4, A3, and 11” × 17” paper typically used
in offices. Another existing international standard (ISO/IEC 17629) for measuring first page out time
addresses first page productivity of business documents at various states (ready, sleep, off) of devices.
This document provides a method and a procedure for measuring single photo printing time of digital
photo printing devices. It allows manufacturers of digital photo printing devices to describe the single
photo printing time and it allows buyers to compare various digital photo printing devices with respect
to representative photo size and usage.

4 Test parameters and conditions
4.1 Test platform test setup procedures
4.1.1 Initial platform setup
The test platform hardware shall be installed as per the manufacturer's instructions. The information
of the test platform hardware shall be recorded as listed in the full detailed report; refer to Annex A
for an example presentation. All settings or selections made during installation that differ from the
application's default settings or operating system’s default settings shall be recorded.
The test platform shall be configured for the appropriate connection environment and the information
shall be recorded as per full detailed report along with all settings and selections that differ from the
installation default configuration.
It shall be verified that the test platform is configured for optimal performance by evaluating system
parameters such as hard disk fragmentation and compression, swap memory size, etc. Any settings,
changes or optimizations made that differ from the installation default condition shall be recorded.
The test platform is now in the initial installation state. All recorded settings shall be included in the
full detailed report.
4.1.2 Initial test state
The test platform shall be restored to the initial installation state before beginning the sequence of
tests for each new printing device. Products that are of the same distinct print system can share testing
and reports. Two or more products or bundles may be part of a distinct print system when they use
the same print mechanism and operating points, and there are no differences that might be expected
to affect performance. Devices with differences that could affect performance are not part of the same
distinct print system, and are different print systems, even if they use the same print mechanism, and
shall not share testing and reports. Record the method used to establish the initial installation state.

4.2 Printing device system setup
Place the printing device on a horizontal surface and setup the printing device according to the
manufacturer's recommendation.
The standard test shall be conducted using the manufacturer's default setup for the given photo-printing
device. All image, print quality, mode and speed modifiers shall be at their factory preset configuration
for the photo-printing device and default installed condition. Disabling manufacturer default installed
features, routines or applications is not allowed.
Examples include, but are not limited to the following: automatic cleaning or calibration cycles, bi-
directional communications and energy save settings.
Testing shall be carried out in the specified modes, regardless of whether they are default settings or
not. For example, if the default driver setting is duplex, the setting shall be changed to simplex for the
tests. Other modes that may need to be modified for specific tests include photo mode, paper size, paper
scaling, and collation. It is allowable to select photo paper. All changes to the default settings shall be
recorded in the full detailed report.
If the content type of photo is available, it shall be set to photo. Print quality level for the photo printing
shall be at factory preset configuration. Any user-selectable draft modes shall not be used.
Sheet selection shall be set to photo sheet. In case of multiple choices are available for photo paper
setting, selection made for testing shall be included in the test report. If user-selectable automatic paper
type detection is available on the device, it shall be disabled.
Additional tests may be conducted using other, non-default, drivers or printing device description
languages provided by the manufacturer for the printing device. Additional tests may also be
conducted using other settings available with the device. Such settings may be, but are not limited to,
print quality and speed modifier choices available in the driver. The results of such additional tests
will be documented as having system parameters that differ from the factory defaults and shown in
comparison to the default system parameter results.
4.3 Printing device connection
A printing device may be connected via a wired network connection (such as Ethernet), direct
connection (such as USB) or wireless connection (such as Wi-Fi, Bluetooth) with which the printing
device is equipped. The connected connection type and version shall be recorded and reported.
4.4 Printing device condition
All supplies used in the test(s), including sheet and printing device consumables, shall be only those
specified as acceptable for use by the manufacturer (or otherwise noted). If available, the number
of pages printed on the engine and printed on the consumables prior to the start of the test shall be
recorded and reported. The device and all of its necessary supplies shall be acclimated in the test
environment prior to conducting the test(s) at least 8 h.
4.5 Sample size
The test file shall be tested and measured at least twice for repeatability. All required tests shall be run
using one device.
4.6 Sheet size and print mode
Size of sheet shall be chosen among 4” × 6”, A6 and L sized sheets that the device is capable of printing. If
a device under testing is not capable of printing on 4” × 6”, A6 or L sized sheet, at least one of 2” × 3”, A4
and 8,5” × 11” sized sheet shall be chosen for the required tests.
© ISO/IEC 2022 – All rights reserved

In all cases the sheet size used shall be indicated in the report as required in Table 2 and as shown
in Table A.1. In the case of bordered printing, the printed image size shall be indicated in the report
as required in Table 2 and as shown in Table A.1. The sheet feed orientation shall be noted in the full
detailed report as shown in Table A.3. When a comparison is made between the single photo printing
time of one device with that of other devices, the measurements shall be done with the same sheet
sizes, the same sheet feed orientation, the same test method and the same testing conditions.
If a device has capability to print both borderless and bordered, the 2” × 3”, 4” × 6”, A6 or L sized sheet
sizes that are supported for borderless printing on the device shall be printed borderless. Scaling for
borderless printing shall be done with the smallest amount of cropping possible by the system and
result in the minimum overspray supported by the device. If borderless printing is not allowed for a
device under testing, 2” × 3”, 4” × 6”, A6 or L sized sheet that are not supported for borderless printing
shall be printed with a border. Scaling for bordered printing shall be done with the smallest amount of
cropping possible by the system and result in the minimum borders on all four sides supported by the
device. If bordered printing is done, it shall be noted in the test report as described in 7.3.
A4, 8,5” × 11”, 11” × 17”, A3 and A3+ sized sheet shall be printed with border and the test image
shall be printed without cropping and shall cover the full image of the test file. Scaling for bordered
printing shall be done by the system. The dimension of the printed image shall be equal or larger than
194 mm × 259 mm for A4 and 8,5” × 11” sized sheet, and 269 mm × 358 mm or larger for 11” × 17”, A3
and A3+ sized sheet. See Figure 1.
NOTE 1 When a 194 mm × 259 mm sized image is placed on the centre of an A4 sheet, the narrower margin
(the long edge) becomes 8 mm for both sides.
NOTE 2 Examples of “system” are operation system of the host
