## Abstract

In one example, a print substrate edge holder includes a first part to hold down the edge of a print substrate without covering any part of the substrate in the print zone and a second part overlapping the first part to collect printing fluid dispensed past the edge of the print substrate.

## Claims

### Claim 1

A print substrate edge holder for use in a printer, comprising:
a first part to hold down an edge of a print substrate in a print zone without covering any part of the print substrate in the print zone; and
a second part overlapping the first part to collect printing fluid dispensed past the edge of the print substrate,
wherein the first part and the second part are adjustable together to different positions across the print zone, and
wherein the first part is detachable from the printer.

### Claim 2 (depends on 1)

The holder of claim 1, wherein: the first part is configured to apply a vacuum to the edge of the print substrate; and the second part comprises a disposable part covering the first part.

### Claim 3 (depends on 2)

The holder of claim 2, wherein the disposable part comprises an absorbent pad.

### Claim 4 (depends on 1)

The holder of claim 1, wherein: the first part comprises a receptacle and holes in the receptacle; and the second part comprises an absorbent pad in the receptacle covering the holes.

### Claim 5 (depends on 4)

The holder of claim 4, wherein the holes are arranged in a line along one side of the receptacle or in a line along the center of the receptacle.

### Claim 6 (depends on 5)

The holder of claim 5, further comprising a vacuum source connected to the holes in the receptacle.

### Claim 7 (depends on 6)

The holder of claim 6, further comprising a plenum between the vacuum source and the holes in the receptacle.

### Claim 8

A print substrate edge holder configured to simultaneously hold down an edge of a print substrate and absorb printing fluid dispensed past the edge of the print substrate, comprising:
vacuum holes to hold down the edge of the print substrate; and
a disposable absorbent pad covering the vacuum holes to absorb printing fluid dispensed past the edge of the print substrate.

### Claim 9

A method comprising simultaneously holding down an edge of a print substrate, dispensing printing fluid onto the edge of the print substrate, and collecting printing fluid dispensed past the edge of the print substrate in a disposable absorbent pad covering vacuum holes.

### Claim 10 (depends on 9)

The method of claim 9, wherein:
holding down the edge of the print substrate comprises applying a vacuum to the edge of the print substrate; and
collecting printing fluid dispensed past the edge of the print substrate comprises absorbing printing fluid dispensed past the edge of the print substrate.
