The print came out — but tiny, cropped at the edges, or washed out. Phone printing adds one extra trap: the app renders the page, not a PC driver, so its page-setup screen is where quality is won or lost. Here is how to set it properly.
When a computer prints, a mature printer driver handles size, scaling and quality. When a phone prints through an app, the app's settings screen is the driver — and its defaults are chosen for speed, not for your document. The four settings that decide almost every bad print are paper size, fit mode, quality mode and colour mode. This guide explains each one with the honest trade-offs.
Many apps default to Letter, the North American size. Indian offices load A4. Print a Letter-formatted page on A4 paper (or the reverse) and you get shrunken content, extra margins, or clipped edges.
Your document was made for one size; the paper may be another. The fit mode decides the compromise.
If text looks mysteriously small, fit-to-page on the wrong paper size is the usual reason — fix the paper size first, then judge the fit mode.
Draft mode saves ink and prints fast, but text looks grey and thin — acceptable only for internal rough copies. Normal is the right daily default. Best/High matters for photos and presentations, and slows the job noticeably. For plain text documents, printing in monochrome even on a colour printer gives darker, sharper text and saves the colour cartridges. One honest limit: an app cannot exceed the printer itself — a 600 dpi office laser will not produce photo-lab prints no matter what the app promises.
Photos: choose borderless only if your printer model supports it, pick the glossy/matte paper type honestly (the printer adjusts ink accordingly), and expect phone screens to look brighter than any print — that gap is physics, not a fault. PDFs: if a PDF prints with missing fonts or shifted layout, the app is re-rendering it; try the app's alternate rendering if offered, or print that file through the PC-bridge route where the real driver handles it.

Set quality to Normal or Best and switch text documents to monochrome. If it is still faded after that, the cartridge or toner itself is the limit, same as on a PC.
Skew is mechanical, not a setting: the paper is not seated squarely in the tray, or the tray side guides are loose. Reload the stack neatly, slide the guides until they just touch the paper, and reprint. App settings cannot straighten a crooked feed.
Only if the printer itself has a duplexer and the app's driver profile exposes it — then a duplex option appears in the app settings. Without a duplexer, the honest workaround is manual: print odd pages, reload the stack, print even pages. The app cannot add hardware the printer does not have.
