Patent number: 11813856Abstract: An example method comprises operating a drive unit to advance a substrate in a substrate advance direction toward a printing station. At the printing station, a first line is printed onto the substrate. A drive unit is instructed to advance the substrate in the substrate advance direction by a target amount, and a second line is printed onto the substrate. The distance between the first and second lines in a direction perpendicular to the substrate advance direction is calculated and, based on the calculated difference, a tension of the substrate is modified.Type: GrantFiled: December 19, 2022Date of Patent: November 14, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ignasi Bonjoch Roma, Josep Maria Bel Calavia, Andreu Vinets Alonso

Publication number: 20230214160Abstract: In example implementations, a method, a device, and a program are provided. The method includes detecting a power increase movement of a printer carriage. A location of the printer carriage is detected at a time of the detected power increase. Based on the detected location of the printer carriage, determine whether the print medium is damaged. The device includes a power monitor to detect a power increase during movement of a printer carriage. A locator detects a location of the printer carriage at the time of the detected power increase. A damage determiner determines, based on the detected location of the printer carriage, whether the print medium is damaged. The program detects a power increase during movement of a printer carriage. Location of printer carriage is detected at time of detected power increase. Based on detected location of the printer carriage, it is determined whether the print medium is damaged.Type: ApplicationFiled: March 17, 2023Publication date: July 6, 2023Applicant: Hewlett-Packard Development Company, L.P.Inventors: Josep Maria BEL CALAVIA, Antonio GRACIA VERDUGO, Andrei Alexandru DAFINOIU

Patent number: 11642881Abstract: Examples relate to a method to print a print job. The method comprise comparing an operational parameter of the print job with a reference operational parameter and determining to perform a maintenance task during the print job based on at least a result of comparing the operational parameter with the reference operational parameter. If the maintenance task is to be performed, the method further comprises determining a safety area on a printable medium and performing a maintenance task on a printable medium.Type: GrantFiled: January 30, 2019Date of Patent: May 9, 2023Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Andreu Vinets Alonso, Antonio Gracia Verdugo, Josep Maria Bel Calavia

Publication number: 20220388800Abstract: A system (300) is provided having a printer (4) to print printing liquid onto a web (6) of media (8). The system (300) has a winding roller (10) on which to roll the web (6) of media (8) after printing. A tensioner (12) to vary the tension in a portion (14) of the web (6) of media (8) is also provided. The portion (14) is a portion of web which is being rolled onto the winding roller (10). Also provided is controller (16) to control the tensioner (12) to vary the tension based on the time taken for the printed printing liquid on the web (6) of media (8) to dry.Type: ApplicationFiled: December 4, 2019Publication date: December 8, 2022Inventors: Antonio Gracia Verdugo, Josep Maria Bel Calavia, Andreu Vinets Alonso
