Printing apparatus, printing system, method of controlling printing apparatus, method of controlling printing system, and storage medium

A printing system comprising:

• a printing apparatus including a carriage capable of loading a plurality of types of print heads, and being configured to print an image by causing the carriage to scan a printing sheet;
• and
• a host device connected to the printing apparatus, wherein
• the printing apparatus includes a service providing unit configured,
• in a case where the print head loaded on the carriage corresponds to a first head configuration, to provide the host device with a first printing service using a first identifier to identify the printing apparatus, and
• in a case where the print head loaded on the carriage corresponds to a second head configuration being different from the first head configuration, to provide the host device with a second printing service using a second identifier being different from the first identifier, and
• the host device includes
• an obtaining unit configured to obtain printability information when an identifier provided from the printing apparatus is an unknown identifier, the printability information being information indicating a printable condition with the printing apparatus,
• a setting unit configured to set the printable condition with the printing apparatus based on the obtained printability information, and
• a transmitting unit configured to transmit a printing job based on the set condition to the printing apparatus.

A method of controlling a printing system provided with

• a printing apparatus including a carriage capable of loading a plurality of types of print heads, and being configured to print an image by causing the carriage to scan a printing sheet, and
• a host device connected to the printing apparatus,
• the method comprising:
• causing the printing apparatus
• in a case where the print head loaded on the carriage corresponds to a first head configuration, to execute a step of providing the host device with a first printing service using a first identifier to identify the printing apparatus;
• and
• in a case where the print head loaded on the carriage corresponds to a second head configuration being different from the first head configuration, to execute a step of providing the host device with a second printing service using a second identifier being different from the first identifier;
• and
• causing the host device
• to execute a step of obtaining printability information when an identifier provided from the printing apparatus is an unknown identifier, the printability information being information indicating a printable condition with the printing apparatus;
• to execute a step of setting the printable condition with the printing apparatus based on the obtained printability information;
• and
• to execute a step of transmitting a printing job based on the set condition to the printing apparatus.
