Different scanners, different options

I have been using Photoshop Elements 2021 for a while with my HP Envy 7800 printer/scanner/copier/fax. With that scanner, I can select anything up to 1200dpi resolution. I am now replacing my HP with an Epson ET-4850 printer/scanner/copier/fax. When I try to scan using that scanner, I can only choose between 100dpi and 300dpi. The Epson software will let me go to 1200dpi, but Photoshop Elements is limited to 300dpi. Unfortunately, the Epson software will not allow me to scan multiple photos at one time and separate them into separate files. Any assistance in getting to at least 600dpi is welcome.

DPI = dots per inch. This is determined by your printer. I have 2 Epson printers and the print quality is superb, esp. with Epson paper & Epson ink.

PPI = pixels per inch. This refers to resolution and can be optimized in PSE via Image menu>resize>image size. In the dialog that opens you can boost the resolution with resampling. Be sure that "Constrain Proportions" is checked. The rule of thumb is that for printing the resolution should be in the 240-300px/in range, though I have printed successfully at a lower value. For web work 72px/in is ok.

That is useful after the image is scanned in, but I am wanting to actually SCAN the image at higher than 300ppi. However, thank you. I may not have been clear that my desire is to SCAN at 600ppi, not convert later, which would lose clarity.

Hi @RbrtLls

I have been looking for the specs for your new all-in-one printer: I have not found anywhere the max resolution, so I believe that it can't do more than 300 dpi. The software can deal with superior quality scanners, that does not give more resolution to your printer/scanner.

Thank you for your response. I have found a work around. The printer/scanner came with a program called Epson ScanSmart. Using the Epson software, I can scan in at up to 9600dpi, then save the scan to the hard drive. Then I can load the saved scan into PSE and accomplish my goals.

On further exploration, I have found that PSE queries the Twain compliant printer scanner for its resolution. My HP printer scanner reports 1200dpi, but my Epson only reports 300dpi.
